Subject: NativeSurface Cleanup (API Change) - Adapt to GlueGen Lock cleanup
 commit: 834b9e530e652b7ff7c5e222720bce3ad2b11c5f

- adapt to GlueGen Lock cleanup
- remove isSurfaceLocked(), use 'null != getSurfaceLockOwner()' instead

Misc:

- remove unused priv./impl. methods
- add @Override

Subject: GLContextImpl/GLDrawableImpl: More fail-safe, cleanup, mark some
 methods final

GLContextImpl: Cleanup
  - release(): simplify the conditions
  - destroy(): allow locked twice before (destroy case)

GLDrawableImpl:
  - fail safe: swapBuffers
  - final methods: getFactoryImpl, toHexString, getGLProfile, getRequestedGLCapabilities,
                   getFactory, isRealized, lockSurface, unlockSurface

Subject: GLContext adds FBO availability to profile mapping; Fix
 GL[Auto]Drawable/GLContext re-association (switch) incl. unit test.

- GLContext adds FBO availability to profile mapping

- GLContext added 'GLDrawable setGLDrawable(GLDrawable readWrite, boolean setWriteOnly)'
  allowing to set the write GLDrawable. This method enables switching context/drawable.

Fix GL[Auto]Drawable/GLContext re-association (switch) incl. unit test
  Commit eed8508ae1132e5f45f788e9cb3f3d5a1050ac70 impl. of GLAutoDrawable's setContext(..)
  enabled proper setting of the GLAutoDrawable context incl. updating the context's drawables.
  Test covers:
  - remove/set (GLContext, GLEventListener) of GL[Auto]Drawable
  - switch (GLContext, GLEventListener) of 2 GLAutoDrawables

From e85e3ec2a73ac35aaf911f0b1e34b234be1622da Mon Sep 17 00:00:00 2001
From: Sven Gothel <sgothel@jausoft.com>
Date: Fri, 6 Jul 2012 01:20:48 +0200
Subject: Enhance Bootsrapping of JOGL around 37% - 40% (1st start in new JVM)
 - GLProfile and GLContext*

GLProfile: Enhance bootsrapping performance of loading GL*Impl class
  - Offthread classloading of all GL*Impl via reflection at startup
    reduces startup time here around 12% (800ms down to 700ms).

GLContext*: Enhance bootsrapping performance of querying available GL profiles
  - Add PROFILE_ALIASING mode, defaults to true - can be disabled w/ property 'jogl.debug.GLContext.NoProfileAliasing'
  - PROFILE_ALIASING:
      If true (default), bootstrapping the available GL profiles
      will use the highest compatible GL context for each profile,
      hence skipping querying lower profiles if a compatible higher one is found.
        Linux x86_64 - Nvidia: 28%,  700ms down to 500ms
        Linux x86_64 - AMD   : 40%, 1500ms down to 900ms

- GL*Impl:
  - make fields final: glProfile, _context, buffer*Tracker and glStateTracker
  - allow null _context/glProfile in initialization (bootstrapping)

- JoglVersion.getDefaultOpenGLInfo(..)
  - add arg: 'boolean withCapabilitiesInfo', allowing to suppres the list of caps

From 20bf031db719f7baa4c6e74734fc999061e08fe2 Mon Sep 17 00:00:00 2001
From: Sven Gothel <sgothel@jausoft.com>
Date: Thu, 19 Jul 2012 21:15:10 +0200
Subject: Bug 599 - FBObject / Offscreen Support - Part 1

- New FBObject implementation handling FBO and it's attachments  *** API CHANGE: Util -> Core ***
  while it's size and sample-count can be reconfigured on the fly.
    - com.jogamp.opengl.util.FBObject -> com.jogamp.opengl.FBObject
    - agnostic to texture unit
    - separate attachments using OO hierarchy reflecting FBO
    - handling MSAA and blitting
    - no FBO destruction for reconfig (attach/detach)

- New GLFBODrawableImpl impl. an FBObject based GLDrawable
   - Instantiated by a dummy native surface (onscreen and invisible)
     hooked up to a dummy GLDrawable, which is the delegation for context creation.

   - Utilizies ProxySurface.UpstreamSurfaceHook for dummy surface
     avoiding specialization for native platforms.

   - TODO: Allow to utilize common surface interface as a
     dummy-surface to supporting API seperation of
     windowing/GL. The latter allows impl. of createGLDrawable(NativeSurface)
     with FBO.

- New OffscreenAutoDrawable (extends GLAutoDrawableDelegate)
  for all offscreen drawables. Shall replace GLPbuffer.

- New GLCapabilities*.isFBO() / setFBO(boolean) to request FBO offscreen,
  similar to isPBuffer(). Rule: if both are requested, FBO shall be favored.

- GLContext adds raw FBO availability query (min. FBO avail),
  FBObject contains fine grained queries (TODO: Move parts to GLContext for efficiency).

- Add framebuffer tracking, allowing fast querying:
  - GLBase/GLContext:
      public int getBoundFramebuffer(int target);
      public int getDefaultDrawFramebuffer();
      public int getDefaultReadFramebuffer();

  - GLContextImpl
      public final void setBoundFramebuffer(int target, int framebufferName)
      .. called by GL impl bind framebuffer

- GL: getDefaultDrawFramebuffer(), getDefaultReadFramebuffer()
  Adding default framebuffer queries being issued by
  GL.glBindFramebuffer(target, 0) w/ a default framebuffer, o.e. zero.
  This allows a transparent use of a custom FBO even in case the applications
  attempts to reset FBO to zero.
    Value flow: GL <- GLContext <- GLDrawable,

- GLCapabilities handle fbo/pbuffer seperate, don't disable the other

- GLContext/GL track read/write framebuffer to be queried by FBObject
  to determine whether to bind/unbind  a framebuffer

- Test cases for multiple FBO w/ and w/o MSAA

Other Features:

- New interface ProxySurface.UpstreamSurfaceHook,
  allowing to hook an upstream surface of unknown type
  providing lifecycle and information (size, ..) callbacks.
  Used for all new dummy NativeSurface impl and SWT GLCanvas.

  - GLContext -> GLDrawable propagation context/drawable lifecycle
    via ProxySurface.UpstreamSurfaceHook allowing dynamic resources
    to react (create, init, ..)
    - contextRealized()
    - contextMadeCurrent()

- SurfaceChangeable -> MutableSurface
  currently only contains setting the surface handle.

  TODO: May need to move ProxySurface.UpstreamSurfaceHook -> MutableSurface.UpstreamSurfaceHook,
        allowing other impl. classes (NEWT OffscreenWindow) to utilize the new
        upstream hookup mechanism - will allow FBO/Dummy window to work.

- SWT GLCanvas using ProxySurface.UpstreamSurfaceHook for proper size
  propagation.

- New GLAutoDrawable::getUpstreamWidget(), allowing GLEventListener
  to fetch the owning Java side UI element (NEWT, SWT, AWT, ..).

- GLDrawableFactory: Removed createOffscreenSurface() - unused and not GL related

- EGLDrawableFactory handles device/profile avail. mapping
  while actually creating context/drawable.
  This allows us to learn whether the ES context is software/hardware as well as FBO avail.

- EGLDrawable: Removed secret buckets of EGL configs :)
  Employ native surface (X11, WGL, ..) to EGL 'mapping' in
  EGLDrawableFactory utilizing new EGLUpstreamSurfaceHook (implements ProxySurface.UpstreamSurfaceHook).

Other Bugs:

- Add CTX_OPTION_DEBUG to ctx/extension cache key since only a debug ctx
  may expose the ARB debug capability.
  This bug caused lack of ARB/AMD debug functionality.

- Fix GLProfile deadlock (debug mode, w/ EGL/ES, no X11),
  dump availability information _after_ lock.

- ImmModeSink draw(): Use GL's glDrawElements(..), don't cast for GL2ES1.
  Fixes use for GL2ES2.

- Fix KeyEvent.getKeyChar() comment (-> only stable for keyTyped(..))

Misc:

- Refined alot of API doc

- New GLExtensions holds commonly used GL extension strings,
  allows better referencing and usage lookup.

- Move GL (interface) decl. to GLBase

- GLBuffers: Cleanup API doc (format, types)

- TextureIO: Add PAM and PPM static suffix identifier

- GLCapabilities getNumSamples() returns 0 if sampleBuffers is disabled, this seems to be more natural.

- finalized a lot

 Random, somewhat old to-do list:
 
 - Non-const array types must be properly released with JNI_COMMIT in
   order to see side effects if the array was copied.
 
-- figure out how to deal with WGL entry points:
-    WINGDIAPI HGLRC WINAPI wglCreateLayerContext(HDC, int);
-    WINGDIAPI BOOL  WINAPI wglUseFontBitmapsA(HDC, DWORD, DWORD, DWORD);
-    WINGDIAPI BOOL  WINAPI wglUseFontBitmapsW(HDC, DWORD, DWORD, DWORD);
-  see commented-out section in make/stub_includes/win32/wingdi.h
-
 - Need a disciplined mechanism for converting char* argument types. For
   example, many C functions accept a "char*" argument with the semantic that
   output data will be written into the buffer pointed to by the

Subject: SWT Update: SWT GLCanvas creates lazy when resource is ready; Create
 new NewtCanvasSWT allowing to parent NEWT windows natively.

SWT GLCanvas creates lazy when resource is ready
  - Ensures drawable and context are created when size > zero and native visualID is valid.
    The latter is platform dependent.
  - Note that you cannot utilize custom GLCapabilities w/ this one,
    since the configurations is already realized - use NewtCanvasSWT.

Create new NewtCanvasSWT allowing to parent NEWT windows natively:
  - Similar to NewtCanvasAWT
  - Allows attaching / detaching NEWT windows

NewtCanvasAWT: Public setNEWTChild(..) fixed

Added test cases for the above - tested on Linux, OSX and Windows w/ SWT

Note: As usual for OSX, add -XstartOnFirstThread

Details:

- NEWT Display has new method: 'EDTUtil setEDTUtil(EDTUtil)'
  allowing to set a custom event dispatch utility.
  We use this to set our SWTEDTUtil for using NEWT w/ SWT
  complying w/ SWT threading constraints.

Subject: Robostness: GLDrawableImpl's contextMadeCurrent()/contextRealized() ;
 GLFBODrawableImpl.contextMadeCurrent(false),
 OffscreenAutoDrawable.setSize(..)

GLDrawableImpl's contextMadeCurrent()/contextRealized():
  - Catch exception which may appear during callback and cont. w/ GLContextImpl's release()/destroy()
    while throwing catched exception at end.

GLFBODrawableImpl.contextMadeCurrent(false):
  - Detect null Colorbuffer ASAP and throw exception

OffscreenAutoDrawable.setSize(..):
  - Catch exceptions at 1) GLFBODrawableImpl.setSize(..) and
    2) GLContext.release() .. throw it in proper order.

From 4dd44b985fe0541be3a3bcd9045d201ed3ca2cc5 Mon Sep 17 00:00:00 2001

Subject: Seamless Integration of an FBObject based GLFBODrawable as
 GLOffscreenAutoDrawable.FBO and as an OffscreenLayerSurface's drawable (OSX)
 - Fix Bugs 569 and 599

Summary:
=========
The new FBObject based GLFBODrawable implementation allows the seamless utilization of
FBO offscreen rendering in single buffer, double buffer and MSAA mode.

The GLFBODrawable uses a parent drawable based on a
dummy surface to allow a GLOffscreenAutoDrawable.FBO creation
or a mutable surface supporting an existing offscreen layer surface (OSX CALayer).

Offscreen GLDrawable's and GLOffscreenAutoDrawable's can be selected via the
GLCapabilities. If simply !onscreen is selected in the caps instance w/o enabling FBO, PBuffer or Bitmap,
the factory will automatically choose regarding availability:
   FBO > PBuffer > Bitmap

Double buffering is supported in MSAA more (intrinsic) and explicit in non MSAA.
It is preferred when delivering resources (texture id's or framebuffer names)
to a shared GLContext.
This is demonstrated in (emulates our OSX CALayer implementation):
  TestFBOOffThreadSharedContextMix2DemosES2NEWT,
  TestFBOOnThreadSharedContext1DemoES2NEWT
and with the OSX JAWT OffscreenLayerSurface itself. FBO is the preferred choice.

+++

Offscreen drawables can be resized while maintaining a bound GLContext (e.g. w/ GLAutoDrawable).
Previously both, drawable and context, needed to be destroyed and recreated at offscreen resize.
Common implementation in GLDrawableHelper is used in the implementations
(NEWT's GLWindow, AWT GLCanvas, SWT GLCanvas).

+++

Tested:
=======

Manually run all unit tests on:
  - Linux x86_64 NVidia/AMD/Mesa3d(ES)
  - OSX x86_64 NVidia
  - Windows x86_64 NVidia
  - Android arm Mali-400/Tegra-2

No regressions.

Disclaimer:
===========
This feature is committed almost in one patch.

Both previous commits were introducing / fixing the capabilities behavior:
 90d45928186f2be99999461cfe45f76a783cc961
 9036376b7806a5fc61590bf49404eb71830de92f

I have to appologize for the huge size and impact (files and platforms) of this commit
however, I could not find a better way to inject this feature in one sane piece.

NativeWindow Details:
=====================

Complete decoupling of platform impl. detail of surfaces
implementing ProxySurface. Used to generalize dummy surfaces and EGL surfaces
on top of a native platform surface.
  - ProxySurface.UpstreamSurfaceHook -> UpstreamSurfaceHook
  - abstract class ProxySurface -> interface ProxySurface + ProxySurfaceImpl
  - Misc. implementations

JOGL Details:
=====================

FBOObject: API Change / Simplification & Usability
  - Removed reference counter to remove complexity, allow user to choose.
  - Add 'dispose' flag for detachColorbuffer(..), allowing to keep attachment alive
  - Fix equals operation of Attachment
  - Check pre-exising GL errors
  - Interface Colobuffer gets lifecycle methods
  - Add static factory methods to create Attachments w/o FBObject instance
  - Reset:
    - Clip min size to 1
    - Keep alive samplingSink, i.e. don't issue resetMSAATexture2DSink(..).
      It gets called at syncFramebuffer()/use(..) later on before actual usage.
      This allows the consumer to utilize the GL_FRONT buffer until (e.g.) swap.
  - misc bugfixes

GLOffscreenAutoDrawable: API Change
  - Reloc and interfacing
  - class com.jogamp.opengl.OffscreenAutoDrawable -> javax.media.opengl.*
    interfaces GLOffscreenAutoDrawable extends GLAutoDrawable
               GLOffscreenAutoDrawable.FBO extends GLOffscreenAutoDrawable, GLFBODrawable
  - Added general implementation and FBO specialization
  - Replacing GLPBuffer (deprecated) .. usable for any offscreen GLDrawable via factory

GLAutoDrawable:
  - Add 'GLDrawable getDelegatedDrawable()'
  - Refine documentation of setContext(..), remove disclaimer and fixme tags

GLDrawableFactory:
  - Refine API doc and it's selection mechanism for offscreen.
  - Add createOffscreenDrawable(..)
  - Add createOffscreenAutoDrawable(..)
  - Add canCreateFBO(..)
  - Mark createGLPbuffer(..) deprectated

Mark GLPBuffer deprecated

New: GLFBODrawable extends GLDrawable

GLCanvas (AWT and SWT): Add offscreen resize support w/o GLContext recreation

GLAutoDrawableBase .. GLWindow:
  - Add offscreen resize support w/o GLContext recreation
  - Remove double swapBuffer call
  -

GLBase/GLContext:
  - Add:
    - boolean hasBasicFBOSupport()
    - boolean hasFullFBOSupport()
    - int getMaxRenderbufferSamples()
    - boolean isTextureFormatBGRA8888Available()

GLContext: Fix version detection and hasGLSL()
  - Version detection in setGLFunctionAvailability(..)
    - Query GL_VERSION ASAP and parse it and compare w/ given major/minor
    - Use parsed version if valid and lower than given _or_ given is invalid.
    - Use validated version for caching (procaddr, ..), version number, etc.

  - Fix hasGLSL()
    Since 'isGL2ES2()' is true if 'isGL2()'
    and the latter simply alows GL 1.*, we confine the result to a GL >= 2.0
    on desktops. FIXME: May consider GL 1.5 w/ extensions.
    -  return isGL2ES2();
    +      return isGLES2() ||
    +             isGL3() ||
    +             isGL2() && ctxMajorVersion>1 ;

GLDrawableImpl:
  - Add 'associateContext(GLContext, boolean)' allowing impl.
    to have a (weak) reference list of bound context.
    This is was pulled up from the OSX specific drawable impl.
  - swapBuffersImpl() -> swapBuffersImpl(boolean doubleBuffered)
    and call it regardless of single buffering.
    This is required to propagate this event to impl. properly,
    i.e. FBODrawable requires a swap notification.
  - Clarify 'contextMadeCurrent(..)' protocol

GLDrawableHelper:
  - Add resize and recreate offscreen drawable util method
  - Simplify required init/reshape calls for GLEventListener
  -

GLGraphicsConfigurationUtil:
  - fixWinAttribBitsAndHwAccel: Reflect sharede context hw-accel bits
  - OSX has no offscreen bitmap, use pbuffer
  - use proper offscreen auto selection if offscreen and no modes are set

EGL Context/Drawable/DrawableFactory: Abstract native platform code out of base classes
  - Use EGLWrappedSurface w/ UpstreamSurfaceHook to handle upstream (X11, WGL, ..)
    lifecycle - in case the EGL resource is hooked up on it.

Invisible dummy surfaces: All platforms
  - size is now reduced to 64x64 and decoupled of actual generic mutable size
  - fix device  lifecycle, no more leaks

+++

OSX
====

Enable support for GLFBODrawableImpl in offscreen CALayer mode
  - NSOpenGLImpl: hooks to calayer native code
  - calayer code:
    - allows pbuffer and texures (FBO)
    - decouple size and draw calls avoiding flickering
    - enable auto resize of calayer tree

MacOSXCGLContext:
  - NSOpenGLImpl:
  - Fix false pbuffer 'usage', validate the pointer
  - If !pbuffer, copy other window mode bits of caps
  -

MacOSXCGLGraphicsConfiguration:
  - Only assume pbuffer if !onscreen
  - Remove reference of native pixelformat pointer

Native code:
  - use 'respondsToSelector:' query before calling 'new' methods
    avoiding an error message where unsuported (prev. OSX versions)
  - if monitor refresh-rate is queried 0, set to default 60hz
  - add missing NSAutoreleasePool decoration

+++

Android / NEWT:
===============

Issue setVisible(..) w/o wait, i.e. queue on EDT,
@Android surfaceChanged() callback. Otherwise we could deadlock:
   setVisible(..) -> EDT -> setVisibleImpl(..) -> 'GL-display'.
the latter may may cause havoc while Android-EDT is blocked [until it's return].

From 923d9dd7f1d40db72d35ca76a761ca14babf147f Mon Sep 17 00:00:00 2001

Subject: Add GLRendererQuirks; Fix shared EGL/ES resources;

Add GLRendererQuirks:
  - Contains centralized 'tagged' workarounds for GL renderer bugs (quirks)
  - Accessible via GLContext and GLDrawableFactory
  - Initialized in GLContext.setAvailability*
  -

Simplify GLGraphicsConfigurationUtil.fixOffscreenGLCapabilities(..) & use Quirks
  - use quirks
  - instead of passing booleans for each config, pass factory & device

Fix shared EGL/ES resources:
  - GLProfile needs to initialize EGLDrawableFactory's shared resources before desktop,
    so EGLDrawableFactory can use the fallback defaultDisplay & defaultSharedResource
    for host mapped sharedResources (hack).

  - If using defaultSharedResources for host mapped ones,
    do not go through initialization cycles - simply map (sharedResource + context).

  - EGLDrawableFactory: Use device's unique-key instead of connection only,
    since the latter causes a collision (EGL-connection == X11-connection).

Subject: Adding Mesa Quirk 'NoSetSwapIntervalPostRetarget': SIGSEGV on
 setSwapInterval() after changing the context's drawable w/ 'Mesa 8.0.4'
 dri2SetSwapInterval/DRI2 (soft & intel)

Analyzing 'TestGLContextDrawableSwitchNEWT' crash at setSwapInterval -> dri2SetSwapInterval
after retargeting the context (new drawable association).
Turns out Mesa's dri2SetSwapInterval may have a bug.

+++

GLContext TRACE_SWITCH: Add drawable handle to debug/trace output.

Subject: GLContext: Produce and expose GLSL version as VersionNumber and
 version string (for shader programs)

Uses GL_SHADING_LANGUAGE_VERSION and parses it via VersionNumber, as well as having a static fallback
using the GL context version.

The value is valid and can be retrieved after ctx has been made current once.

Subject: GLRendererQuirks: Add RequiresBoundVAO (w/ impl.), GLSLBuggyDiscard
 (todo) ; GLContextImpl: Bind default VAO if having quirk RequiresBoundVAO.

OSX w/ OpenGL >= 3 core context implementation requires a bound VAO for vertex attribute operations,
i.e. VertexAttributePointer(..). This has been experienced on OSX 10.7.5, OpenGL 3.2 core w/ Nvidia GPU
and in several forum posts. Such 'behavior' violates the GL 3.2 core specification,
which does not state this requirement, hence it is a bug. (Please correct me if I am wrong!)

GLContextImpl works around this quirk, by generating a default VAO and binds it at 1st makeCurrent (@creation)
and deletes it at destroy. This is minimal invasive since no action is required for subsequent makeCurrent or release.
We assume if a user uses and binds a VAO herself, she will mind this quirk.

Note: We could enhance this workaround by quering for a currently bound VAO at makeCurrent() and bind our default if none.
However, we refrain from this operation to minimize the workaround and complexity.

Subject: GLRendererQuirks.RequiresBoundVAO: Removed, it _is_ in the GL 3.2
 core spec - Setting up default VAO for all GL >= 3.2 core ctx.

Refines commit 9b6448b1d54716fd455c0cad0c6133c0edeb3bb8

Due to GL 3.2 core spec: E.2. DEPRECATED AND REMOVED FEATURES (p 331)
"There is no more default VAO buffer 0 bound, hence generating and binding one
to avoid INVALID_OPERATION at VertexAttribPointer."

More clear is GL 4.3 core spec: 10.4 (p 307):

"An INVALID_OPERATION error is generated by any commands which
modify, draw from, or query vertex array state when no vertex array is bound.
This occurs in the initial GL state, and may occur as a result of BindVertexAr-
ray or a side effect of DeleteVertexArrays."

+++

I just have read (same spec) 2.10 (p 46/47):

"An INVALID_OPERATION error is generated if any of the *Pointer commands
specifying the location and organization of vertex array data are called while zero
is bound to the ARRAY_BUFFER buffer object binding point, and the pointer argu-
ment is not NULL."

.. which only constraints the *Pointer command use to _VBO_, not forcing a VAO.

Subject: Cleanup GLContext special entries:
 getOffscreenContextPixelDataType(), getOffscreenContextReadBuffer(), .. ; Add
 GLFBODrawable API entries for multi buffering (no impl. yet); GLJPanel 1st
 simplification using offscreen drawable

- Cleanup GLContext special entries: getOffscreenContextPixelDataType(), getOffscreenContextReadBuffer(), .. ;
  - add: getDefaultReadBuffer() (-> exposed via GLBase as well)
  - add: isGLOrientationFlippedVertical()
  - add: getDefaultPixelDataType()
  - removed impl: getOffscreenContextPixelDataType()
  - removed impl: getOffscreenContextReadBuffer()
  - removed impl: offscreenImageNeedsVerticalFlip()

- Add GLFBODrawable API entries for multi buffering (no impl. yet);
  - TODO: Add implementation code in GLFBODrawableImpl

- GLJPanel 1st simplification using FBO
  - Use above new GL/GLContext entries
  - Fix: getNativeSurface() and getHandle()
  - TODO:
    - Remove distinction of 'pbuffer' and 'software',
    - Use GLDrawableFactory.createOffscreenDrawable(..)
    - Use GL for FBO swapping

Subject: Fix Bug 642 TestJSplitPaneMixHwLw01AWT (AWT-GLCanvas); Robustness
 GLContext/GLDrawable

- Fix Bug 642 TestJSplitPaneMixHwLw01AWT
  On Windows platform when mixing hw/lw JSplitPanel,
  the GLCanvas is removed and added when splitter is moved.
  The lack of robustness (see below) lead to an exception.

  Note: Only w/ GLJPanel (no hw/lw mixing) the splitter can be moved
  in both direction. Only here it is guaranteed that the GL component
  will survive the action.

- Fix AWT-GLCanvas EDT Runnable: swapBuffer().. / display(..)
  - Check drawable.isRealized() within the lock on the performing thread.
    This is not possible before issuing the EDT Runnable action
    since we cannot hold the lock beforehand.

- Robustness GLDrawableImpl
  - boolean realized -> volatile boolean realized
  - remove 'synchronized' on isRealized() and setRealized(..)
  - Use dbl-checked locking on 'realized' test for swapBuffers() and setRealized(..)

- Robustness GLContextImpl
  - Catch createImpl(..) exception and properly return CONTEXT_NOT_CURRENT

Subject: Bug 642 / Refine 1ae0737f34143a5ed655bd9c4d5fe9b0437c7774:
 GLContextImpl.makeCurrent() - Handle !drawable.isRealized() early, don't
 catch 'create' Exception

Catching the createImpl() exception could be confusing, since it shall succeed.
Such exception is required to hint a platform bug and to debug it.

Hence testing drawable.isRealized() upfront is preferrable, i.e. catching a well known case
for returning CONTEXT_NOT_CURRENT.

Subject: Fix Bug 658 (Mesa 9.0 3.1 Intel compat quirk, 3.1 core only) ; No
 PROFILE_ALIASING compat -> core ; Fix setGLFunctionAvailability(..) failure
 path @ profile query

- Add GLRendererQuirks.GLNonCompliant, marking a GL context/profile non compliant.
  Currently: 'Mesa DRI Intel(R) Sandybridge Desktop' && 3.1 compat profile

- Fix Bug 658 (Mesa 9.0 3.1 Intel compat quirk, 3.1 core only)
  Detect case using new GLRendererQuirks.GLNonCompliant in setGLFunctionAvailability() and return 'false'.

- No PROFILE_ALIASING compat -> core
  Use true core GL profiles / context if available to ensure
  proper API behavior across platforms due to different functionality.
  E.g. don't use GL3bc if GL3 is requested.

- Fix setGLFunctionAvailability(..) failure path @ profile query
  Destroy temp context & zero result to cont. iterating through GL versions.
  This missing cleanup lead to returning the faulty GL context handle and it's mapping/usage.

Subject: Cleanup / Simplify: setGLFunctionAvailability(..) /
 createContextARBVersions(..) GL Version Validation

String or integer based GL version validation now happens in setGLFunctionAvailability(..)
depending on the requested profile.

Due to the 'strictMatch' argument the method fails early when unsatisfied
also allowing to simplify createContextARBVersions(..) implementation.

Subject: setGLFunctionAvailability(..): Unify GLInt and GLString version
 validation; Refines commit b6ae4e4dcbd740dd57de9dc3280d943e98cdaa76

- Limit getGLIntVersion() w/ non ARB ctx to 3.0 - similar to getGLVersionNumber(.., String).

- GLInt only proceeds w/ valid version

- Always test GLInt version before GLString version,
  cont. w/ GLString version if GLInt failed.

- Fail if strictMode and GLInt failed, but GLString reports GL >= 3.0

- Fail is strictMode and neither GLInt nor GLString could validate version

- Clear glError before succeeding (could be tainted by GLInt version test)

Subject: Adding GEOMETRY_SHADER support in ShaderCode, adding core
 GL3/GEOMETRY_SHADER unit tests. ; Simplified GLContext version number

- Adding GEOMETRY_SHADER support in ShaderCode, adding core GL3/GEOMETRY_SHADER unit tests

  Chuck Ritola reported in December 2012 that we lack support of GEOMETRY_SHADER
  and he provided a test case.

  The latter is cleaned up to use GL3 core profile features only
  tesing a pass-through and the flip-XYZ geometry shader.

  ShaderUtil is fixed.

- Simplified GLContext version number
  The OpenGL major/minor version is now hold in a VersionNumber instance
  to simplify usage. Also expose it via getGLVersionNumber() while marking
  getGLVersionMajor() and getGLVersionMinor() deprecated.

From 34687193484b2404d83eebf5d008b71d54e52286 Mon Sep 17 00:00:00 2001
From: Sven Gothel <sgothel@jausoft.com>
Date: Fri, 18 Jan 2013 03:38:35 +0100
Subject: Fix Bug 669: Recursive GLContext makeCurrent()/release()

Culprit:
  GLContext's makeCurrent() didn't clear the boolean flag 'unlockContextAndSurface'
  in case the context is already current (-> recursion).
  Above case was detected within a code block tailed by a finally block,
  which acted on mentioned flag, i.e. called lock.unlock() and hence decremented the lock count
  even though the method return w/ successful state.

  Fixed.

Added debug code:
  GLContext.release() debug code (DEBUG | TRACE_SWITCH),
  recording stack trace of last release() call, which is dumped in case no current was current.

Added 2 unit tests:
  - Simple recursive GLContext makeCurrent()/release() from within GLEventListener's display().
    Test also validates lock count and lock ownership.

  - GLAutoDrawable display() of another GLAutoDrawable
    from within GLEventListener's display(..).

From b738983638703bb721ee4c9820c8ef43e2252e73 Mon Sep 17 00:00:00 2001
From: Sven Gothel <sgothel@jausoft.com>
Date: Thu, 24 Jan 2013 17:24:22 +0100
Subject: Bug 665 (part 1) - Allow dis-association of GLContext's GLDrawable ..

Changes allowing re-association (incl. null) of GLContext/GLDrawable:

- GLAutoDrawable: Refine API doc 'setContext(..)'

- GLContext: Refine API doc: 'setGLDrawable(..)' 'getGLDrawable()'

- GLContextImpl.setGLDrawable(): Handle null drawable

- GLAutoDrawableDelegate/GLAutoDrawableBase: Allow null GLContext

- GLDrawableHelper.switchContext(..)/recreateGLDrawable(): Balance GLContext.setGLDrawable(..) calls

- New GLEventListenerState, holding state vector [GLEventListener, GLContext, .. ]
  impl. relocation of all components from/to GLAutoDrawable.

- GLDrawableUtil
  - Using GLEventListenerState for swapGLContextAndAllGLEventListener(..)

+++

NEWT Window*:
  - getDisplayHandle() is 'final', no more 'shortcut' code allowed
    due to re-association incl. display handle.

  - close*:
    - close config's device (was missing)
    - null config

+++

Changes allowing reconfig of Display handle as required
to re-associate pre-existing GLContext to a 'window':

- AbstractGraphicsDevice: Add isHandleOwner() / clearHandleOwner()
  - Impl. in X11GraphicsDevice and EGLGraphicsDevice, NOP in DefaultGraphicsDevice

- DefaultGraphicsConfiguration add 'setScreen(..)'

- MutableGraphicsConfiguration
  - Make DefaultGraphicsConfiguration.setScreen(..) public

- NativeWindowFactory add 'createScreen(String type, AbstractGraphicsDevice device, int screen)'
  - Refactored from SWTAccessor

- NativeWindow x11ErrorHandler: Dump Stack Trace in DEBUG mode, always.

From 2fe180fbee15b82e2ae14fe3c95887db246c874d Mon Sep 17 00:00:00 2001
From: Sven Gothel <sgothel@jausoft.com>

Subject: Bug 665 (part 3) - Allow dis-association of GLContext's GLDrawable ..
 - Add EGL/ES2 tests, attempt to fix wrapped EGL case

- Bug 665 (part 2) was commit 7fd5f76e1eb4bbf93fe9b1171744bd755d8f96e4

- Add EGL/ES2 tests in
  - TestGLContextDrawableSwitch01NEWT
  - TestGLContextDrawableSwitch11NEWT

- Attempt to fix wrapped EGL case (incomplete)
  - Using EGL/ES w/ non native EGL device/surface, but natively wrapped instances (most of the cases),
    a 'complicated' delegation of
       Native-Upstream -> EGL-Proxy -> EGL-Instance
    is being used heavily relying on the objects lifecycle.
    GLEventListenerState tries to roll back the realized state
    and even sets the upstream device handle,
    but this doesn't seem to be sufficient on X11.

Discussion:

It might turn out that we only can implement the survival of GLContext
and it's display device reliable w/ EGL within the GLAutoDrawable implementation,
which can hold the previous not destructed instances.

Subject: Relax GLContextImpl.setGLFunctionAvailability(..)'s Version Matching
 if testing major < 3 versions. (Bug 679)

On OSX, we 'only' support the ctx ARB creation and hence have no !ARM fallback.

If querying a version [2.0 .. 3.0] for GL2, it is acceptable if a valid OpenGL version is lower, e.g. 1.4.

Subject: Bug 665: Allow re-association of GLContext/GLEventListener to a
 GLDrawable (Part 4)

Note:

  - GLEventListenerState preservs the GLAutoDrawable state,
    i.e. GLContext, all GLEventListener and the GLAnimatorControl association.

  - GLEventListenerState may be utilized to move the state from a dying GLAutoDrawable,
    to be moved to a new created GLAutoDrawable at a later time.

  - GLEventListenerState will be made public soon.

+++

Exessive unit tests cover the new feature, tested manually on GNU/Linux/X11 and OSX(Java6/Java7).

+++

- GLAutoDrawable
  - Change 'setContext(..)' to allow the destruction of the unbound old context:
      'setContext(GLContext newCtx)' -> 'setContext(GLContext newCtx, boolean destroyPrevCtx)'

  - Implementations: Properly implement 'setRealized(..)' incl. obeying threading constraints if exists.
    Method is being utilized at least for GLEventListenerState.moveTo(..)
    to unrealize and realize the drawable resources.

+++

Fix propagation of GLContext/GLDrawable association change (Bottom -> Top):

  GLDrawableImpl.associateContext
      GLContextImpl.associateDrawable
          GLContextImpl.makeCurrent
          GLContextImpl.destroy
          GLContext.setGLDrawable
              ...
              GLDrawableHelper.switchContext
                  GLAutoDrawble.setContext

associateDrawable(..)/associateContext(..) unifies and hence:
    - GLContextImpl.contextRealized() (removed)
    - GLDrawableImpl.contextRealized() (removed)
    - GLDrawableImpl.associateContext(..) (merged)
    - MacOSXCGLContext.drawableChangedNotify(..) (removed)

+++

- EGLUpstreamSurfaceHook.evalUpstreamSurface() validates the surface's device for reusage,
  which is valid in case of GLEventListenerState.moveTo(..)

- MacOSXCGLContext.NSOpenGLImpl: pixelFormat replaces NSOpenGLLayerPfmt and has simplified lifecycle [create..destroy],
  while native NSOpenGLLayer code only holds the reference until released.

Subject: OSX/CALayer: OSX/CALayer Threading Part3 - Run CALayer ops in a
 streaming design on main-thread w/o [infinitive] blocking

History:
  Part1   commit 896e8b021b39e9415040a57a1d540d7d24b02db1 (Run CALayer Ops on current thread to avoid blocking)
  Part2   commit 28c6472335b924080d638b33a28f8f4eedb459b1 (Run CALayer Ops on main-thread w/o blocking)

Dependency:
  GlueGen commit 4becdfa125b07ff969d6540e1112735b53cd15eb (Fix RecursiveLockImpl* Timeout corner case)

Part2 misses essential locking of the OpenGL context (and it's surface upfront) while creating the
NSOpenGLLayer instance. The latter instantiates a OpenGL context shared w/ JOGL's, hence it cannot be locked.

Encapsulating NSOpenGLLayer creation/attachment and it's detachment/release in sub-classes
AttachNSOpenGLLayer and DetachNSOpenGLLayer, where instances will be streamed on main-thread.

Both tasks are triggered at associateDrawable(boolean bound).

The mentioned GL context locking requires disturbs the 'streaming' design considerably in AttachNSOpenGLLayer.
It is solved by attempt to acquire the recursive lock of the surface and the context via 'tryLock(maxwait)'
w/ screen-vSync-period/2. If the locks could not be acquired completly, the AttachNSOpenGLLayer instance
will be re-queued to the main-thread for later execution.

Before DetachNSOpenGLLayer is being streamed, it is validated whether AttachNSOpenGLLayer did run.
A recursive situation does happen w/ resizing an offscreen pbuffer drawable! Hence extra care is being taken.

Subject: GLDrawable: Refine API doc; GLDrawableImpl: Balance
 createHandle()/destroyHandle(); Handle LOCK_SURFACE_CHANGED in lockSurface()
 ; GLContextImpl.makeCurrent(): Fix drawable handle validation.

GLDrawable: Refine API doc (realized/handle)
  - Lifecycle of the drawable handle was not clear
  - Ephasizing handle's dependency on NativeSurface's lock state and drawable's realization

GLDrawableImpl: Balance createHandle()/destroyHandle()
  - updateHandle() -> createHandle()
  - ensure both are balance, see below

GLDrawableImpl: Handle LOCK_SURFACE_CHANGED in GLDrawableImpl's lockSurface()
  - call destroyHandle() and createHandle()

GLContextImpl.makeCurrent(): Validate drawable handle if realized only.
  - it is valid to have an invalid drawable handle if not realized (see above)

Subject: GLContextImpl: destroy(): Fix null drawable check;
 makeCurrentWithinLock(): Add drawable size validation before attempt to
 create context; MacOSXCGLContext: Explicit exception for Null
 AttachGLLayerCmd.

GLContextImpl:
  - destroy():
    - Fix null drawable check
      Only if the GLContext isCreated(), we require a drawable to be set.

    - Proper name of associateDrawable Exception

  - makeCurrentWithinLock():
    - Add drawable size validation before attempt to create context.
      - 'makeCurrent()' shall never be called w/o proper sized drawable, i.e. > 0x0.
      - returns CONTEXT_NOT_CURRENT, if drawable size is <= 0x0

MacOSXCGLContext:

  - Explicit exception for Null AttachGLLayerCmd.
    In case context creation has failed via makeCurrent(),
    AttachGLLayerCmd may never been issued and hence maybe NULL.
    Catch this case and send a meaningful exception,
    which is catched and fwd in GLContext.destroy().

Subject: Fix Bug 692: Add tracking of VERTEX_ARRAY_BINDING, and enable
 allowing a bound non default VAO to pass VBO enabled test, even if VBO is
 disabled.

VAO is available if: GL >= 3.0 or is having GL_ARB_vertex_array_object extension.

checkBufferObject(..) checks whether VERTEX_ARRAY_BINDING has a non default VAO bound in case
no VBO is being bound and VAO is allowed.

glBindVertexArray(int) is being tracked, i.e. on state VERTEX_ARRAY_BINDING

Subject: Fix Bug 705 - Cleanup & Generalize Commit
 5b47372590ec715647ebbd75d70c41ec7a64485a ; Close X11 Display in
 isDeviceSupported()

- Moved GL vendor version parsing to GLVersionNumber

- Moved X11Util.markAllDisplaysUnclosable() trigger into SharedResource creation of
  - X11GLXDrawableFactory
  - EGLDrawableFactory

- GLProfile is back to pre 5b47372590ec715647ebbd75d70c41ec7a64485a,
  i.e. contains no quirk artifact (clean)

- Close X11 Display in X11GLXDrawableFactory.isDeviceSupported()
  Regression of 9a4fcc7ea4ec61e4ceed791acced734ac04ea270

- TODO: Remove X11Util markAllDisplaysUnclosable detection code ?

Notes to Martin:
  - Use TAB == 4 SPACES
  - No author names into source code, git commit log is enough.
  - No need to tag your edits, the diff is enough.

Subject: Fix Bug 720: Unify all platform specific GLContextImpl
 specializations; Fix Bug 719 - Windows BITMAP Offscreen Orientation is not
 propagated through API

Fix Bug 719 - Windows BITMAP Offscreen Orientation is not propagated through API
  Depends on Bug 720, since cleaning up GLContextImpl* is required to move
  property 'GLContext.isGLOrientationFlippedVertical()'
  to 'GLDrawable.isGLOriented()' where it belongs!

  Windows BITMAP GLDrawable impl. isGLOriented() shall return false,
  while we keep the BITMAPINFOHEADER's height field negative
  to remove the need for vertical flip when used w/ AWT or Windows, ..

  Then property 'GLDrawable.isGLOriented()' has to be recognized throughout the
  utility functions, i.e. TextureData's mustFlipVertically and hence TextureIO writer.

Fix Bug 720: Unify all platform specific GLContextImpl specializations
  GLContextImpl shall have only _one_ unique platform derivative
  to allow proper swapping of GLDrawables of any type via:
    - 'GLAutoDrawable.setContext(GLContext newCtx, boolean destroyPrevCtx)', which calls
    - 'GLContext.setGLDrawable(GLDrawable readWrite, boolean setWriteOnly)'

  Exception: External context may be specialized.

  All drawable specific property handling shall be provided
  and implemented (if possible) via GLDrawable specializations.

- GLContext.isGLOrientationFlippedVertical() -> GLDrawable.isGLOriented()
  - PNGImage.createFromData() takes 'isGLOriented' to properly handle vertical flipping simply by line ordering
  - TextureIO's PNG writer passes TextureData's getMustFlipVertically() as isGLOriented to PNGImage.createFromData()
  - GLReadBufferUtil respects GLDrawable's isGLOriented() when creating TextureData instance.
  - Screenshot respects GLDrawable's isGLOriented()

- Screenshot is deprecated, use GLReadBufferUtil.

- Removed all PBuffer attributes, i.e. floatingPoint, RenderToTexture and RenderToTextureRectangle.
   - Allows removal of special pbuffer handling in GLContext* implementations.
   - Removed also from GLCapabilities*
   - Removed from deprecated GLPbuffer

  Impact:
    - Low, users who desire to render into a texture shall use our FBO GLOffscreenDrawable.
    - Only use case was the deprecated GLPbuffer
    - floating point framebuffer technology is still patented anyways :)

- Removed Java2DGLContext, which was only used for OSX's GLJPanel Java2D bridge,
  which is no more supported anyways.

Subject: Simplify GLDrawableFactory's SharedResource Query Methods; Move
 WindowsWGLDrawableFactory Quirks to GLRendererQuirks
 (NeedCurrCtx4ARBPixFmtQueries, NeedCurrCtx4ARBCreateContext); Bug 706:
 Confine NeedCurrCtx4ARBCreateContext to [Windows, ATI, driver < 12.102.3);
 Avoid possible NPE @ GLContext.getGLVendorVersionNumber()

- Simplify GLDrawableFactory's SharedResource Query Methods
  - Moving common methods to GLDrawableFactory/GLDrawableFactoryImpl
    while reusing common methods to SharedResourceRunner.Resource.
  - All factories SharedResources impl. SharedResourceRunner.Resource.

- Move WindowsWGLDrawableFactory Quirks to GLRendererQuirks (NeedCurrCtx4ARBPixFmtQueries, NeedCurrCtx4ARBCreateContext)
  - For better maintenance, move the mentioned quirks from the windows factory to our common place,
    being detected within GLContextImpl after each context creation.

- Bug 706: Confine NeedCurrCtx4ARBCreateContext to [Windows, ATI, driver < 12.102.3)
  - Before we added this quirk if [Windows, ATI],
    however, we have hopes that the new drivers will suffice for all
    as tested successful on my test machine (AMD Radeon HD 6300M Series, amd_catalyst_13.5_mobility_beta2).

- Avoid possible NPE @ GLContext.getGLVendorVersionNumber()
  - GLContext.getGLVendorVersionNumber() never returns 'null' but a zero version instance instead!
  - Add API doc.

- Use mixed case names in GLContextImpl.setRendererQuirks(..).

Subject: GLVersionNumber: Fix vendor version parser; Adapt to GlueGen commit
 959d6d83ec26152343d538287c02eeebf0dcf238

Adapt to GlueGen commit 959d6d83ec26152343d538287c02eeebf0dcf238:
  - Use only RegExp and cache default (no wrapped whitespace tokenizer)
  - String match: Store end-of-match and flag defined components.
  - Remove manual parsing, utilize VersionNumber
  - No need to look further for 'updated' GL version, (probably the vendor version),
    since we utilize the ARB version number as set at creation.

Fix vendor version parser:
  - Cut off GL version part of versionString (fixes case where GL version was interpreted as vendor version)
  - Loop through remaining string until a valid version number w/ major.minor has been found

Subject: Bug 759:

Currently, the compatibility context on Mesa >= 9.1.3 seems to be
very broken. The core contexts, however, seem to be quite stable. This
commit both reduces and widens the scope of the current Mesa quirk to
include only Compatibility contexts on OpenGL > 3 || 3.n where n >= 1.

Subject: Add Support for GL 4.3 (Bug 716) and ES 3.0 (Bug 717)

ES3 / GL4.3:

- Update all EGL, GLX, WGL and GL (desktop and mobile) khronos headers to latest version.
  - GL3/gl3* -> GL/glcorearb*

  - Explicitly preserve ES2_compatibility and ES3_compatibility in header,
    most extension grouping was removed in new headers.

  - Always load all GLHeader to ensure proper extension association across all profiles.

  - Unified method signatures

  - Added GL_EXT_map_buffer_range to core

  - Using common 'glMapBufferImpl(..)' for all glMapBuffer(..) and glMapBufferRange(..) impl.

  - Init necessary fields of GL instances via 'finalizeInit()' called by reflection, if exist.
    This allows removing initialization checks, i.e. for all buffer validations.

- BuildStaticGLInfo: Can handle new GL header structure, i.e. one CPP extenstion block incl. define + funcs.

- GLJavaMethodBindingEmitter: Simply print the

- No GL duplication due to new intermediate interfaces, see below

- OO lineare inheritance (Added GL2ES3, GL3ES3 and GL4ES3 intemediates):
  GLBase - GL - GL2ES2 - GLES2
  GLBase - GL - GL2ES2 - GL2GL3 - [ GL2, GL3 ]
  GLBase - GL - GL2ES2 - GL2ES3 - GL3ES3 - [ GL3 ]
  GLBase - GL - GL2ES2 - GL2ES3 - GL3ES3 - GL4ES3 - [ GLES3, GL4, .. ]

- Expose 'usable' intermediate interfaces GL3ES3 and GL4ES3 in GLBase/GLProfile/GLContext
  via is*() and get*().

- GLContext*:
  - isGL3core() is true if [ GL4, GL3, GLES3 ] (added GLES3)

  - Added ctxProfile argument to allow handling ES versions:
    - getMaxMajor(..), getMaxMinor(..), isValidGLVersion(..) and decrementGLVersion(..)
    - mapGLVersions(..) prepared for ES ARB/KHR validation

  - EGLContext checks ES3 (via old ctx's GL_VERSION)

- ExtensionAvailabilityCache adds GL_ES_Version_X_Y for ES.

- Prelim tests w/ Mesa 9.1.3
  GL Version     3.0 (ES profile, ES2 compat, ES3 compat, FBO, hardware) - OpenGL ES 3.0 Mesa 9.1.3 [GL 3.0.0, vendor 9.1.3 (Mesa 9.1.3)]

- TODO:
  - Use KHR_create_context in EGLContext.createContextARBImpl(..)
  - More tests (Mobile, ..)

+++

Misc:

- GLContext*:
  - Complete glAllocateMemoryNV w/ glFreeMemoryNV.

-/* This is a draft release of gl3.h, a header for use with OpenGL 3.1, and
- * 3.2 and later core profile implementations. The current version is
- * available at http://www.opengl.org/registry/ . Please don't package
- * gl3.h for release with other software until it's out of draft status.
- * The structure of the file may change significantly, and the details
- * will probably change slightly as we make sure exactly the right set
- * of interfaces is included.
- *
- * gl3.h last updated on $Date: 2012-01-26 02:57:23 -0800 (Thu, 26 Jan 2012) $
- *
- * RELEASE NOTES - 2012/01/26
- *
- * gl3.h should be placed under a directory 'GL3' and included as
- * '<GL3/gl3.h>'.
- *
- * gl3.h is supposed to only include APIs in a OpenGL 3.1 (without
- * GL_ARB_compatibility) or OpenGL 3.2-4.2 (inclusive) core profile
- * implementation, as well as interfaces for newer ARB extensions which
- * can be supported by the core profile. It does not, and never will
- * include functionality removed from the core profile, such as
- * fixed-function vertex and fragment processing.
- *
- * Implementations of OpenGL 3.1 supporting the optional
- * GL_ARB_compatibility extension continue to provide that functionality,
- * as do implementations of the OpenGL 3.2+ compatibility profiles, and
- * source code requiring it should use the traditional <GL/gl.h> and
- * <GL/glext.h> headers instead of <GL3/gl3.h>.
- *
- * It is not possible to #include both <GL3/gl3.h> and either of
- * <GL/gl.h> or <GL/glext.h> in the same source file.
- *
- * We welcome feedback on gl3.h. Please register for the Khronos Bugzilla
- * (www.khronos.org/bugzilla) and file issues there under product
- * "OpenGL", category "Registry". Feedback on the opengl.org forums
- * may not be responded to in a timely fashion.

From 6136457f10d020c779adc78641d0048f77ab1635 Mon Sep 17 00:00:00 2001
From: Sven Gothel <sgothel@jausoft.com>
Date: Mon, 15 Jul 2013 22:49:47 +0200
Subject: Fix BuildComposablePipeline's isGL*/getGL* ; GLBase:
 getDownstreamGL()/getRootGL(); GLContext.isGL* added proper API doc.,
 isGL3core()/hasNoDefaultVAO() and getDefaultVAO().

- Fix BuildComposablePipeline's isGL*/getGL* (regression of commit 3a0d7703da32e9a5ddf08a334f18588a78038d880)

- GLBase: getDownstreamGL()/getRootGL()
  Allows user traversing through pipelined GL instances.
  Also added getRootGL() to GLContext.

- GLContext.isGL* added proper API doc.: We test the actual context, not the profile.

- GLContext isGL3core()/hasNoDefaultVAO() and getDefaultVAO()
  - Move isGL3code() def. back to pre 3a0d7703da32e9a5ddf08a334f18588a78038d880, i.e. Includes [ GL4, GL3 ] w/o GLES3.
  - Added hasNoDefaultVAO() and getDefaultVAO() .. incl. [ GL4, GL3, GLES3 ]

From 1a20ef3aa1dc9acedd7da0475ee19d4c40b18498 Mon Sep 17 00:00:00 2001
From: Sven Gothel <sgothel@jausoft.com>
Date: Tue, 16 Jul 2013 20:46:42 +0200
Subject: Redefine: isGLES3Compatible() and isGL4ES3(), i.e. allow GL4ES3 usage
 in case proper ES3_compat is given.

isGLES3Compatible() and isGL4ES3() of GLBase _and_ GLContext
includes [ GL >= 4.3, GL >= 3.1 w/ GL_ARB_ES3_compatibility and GLES3 ].

Tested GL 'aliasing' w/ TestGLProfile01NEWT, i.e. isGL*() and getGL*().

From 78abc89be7f3935f26802cc0db33f61fc2c65de0 Mon Sep 17 00:00:00 2001
From: Sven Gothel <sgothel@jausoft.com>

Subject: Fix OSX GL-core lack of pbuffer:
 GLDrawableFactory.canCreateGLPbuffer(..) add GLProfile argument, similar to
 canCreateFBO(..)

In case a compatible non-core profile is requests, canCreateGLPbuffer(..) returns false on OSX.

Subject: Fix Bug 862: Fix GL Version Validation / NVidia GTX550 driver 331.13
 - 64bit Linux - No compatibility GLProfile (GL2, >= GL3bc)

Fix GL Version Validation:
  We shall not rely on our known good versions when validating a queried GL context version,
  but allow some 'room' for a higher version post JOGL release while still
  cutting off 'odd versions'.

  While GL version detection, we always iterate from the highest known version
  down to the lowest. Hence 'GLContext.isValidGLVersion(..)' is satisfied
  by validating the lowest version number but allowing a higher than known one.

  Now we would return 'invalid' for a version >= 6.

  It is enough to clip to the maximum known version when iterating,
  allowing the highest unknown version to be available.

  GLContext.isValidGLVersion(..):
    Returns true, if the major.minor is not inferior to the lowest
    valid version and does not exceed the highest known major number by more than one.

    The minor version number is ignored by the upper limit validation
    and the major version number may exceed by one.

    The upper limit check is relaxed since we don't want to cut-off
    unforseen new GL version since the release of JOGL.

    Hence it is important to iterate through GL version from the upper limit
    and 'decrementGLVersion(..)' until invalid.

Add GL Version 4.4 to valid known versions.

Remove ES3 desktop detection, which is impossible
  Regression of commit 3a0d7703da32e9a5ddf08a334f18588a78038d88 (ES3 support)

Subject: Bug 867 OSX [Common Code]: Trigger
 GLRendererQuirks.GL4NeedsGL3Request and make it sticky; Only alias profiles
 if HW-Accelerated!

Only alias profiles if HW-Accelerated!
GLContextImpl.mapGLVersions(..) shall not map a higher profile to a lower if it is a software renderer.

+++

GLContextImpl.mapGLVersions(..) attempts to trigger GLRendererQuirks.GL4NeedsGL3Request if OSX 10.9
by creating a GL3 core context first.

+++

GLContextImpl.setGLFunctionAvailability():
  - On OSX 10.9: Detect GLRendererQuirks.GL4NeedsGL3Request and make it sticky (per device)
    while 'withinGLVersionsMapping'

  - Merge sticky quirks w/ local quirks

+++

TestGearsES2NEWT: Add cmdline '-gl2' to force GL2 profile.

From: Sven Gothel <sgothel@jausoft.com>

Subject: Bug 776 GLContext Sharing: Refine API for relaxed and lazy GLContext
 sharing ; Fix GLContext memory contract (volatile)

(Unit test remarks see below)

- Add shared GLContext queries
  - Refined GLContextShareSet:
    - Use IdentityHashMap since GLContext's can only be identical w/ same reference (footprint, performance)
    - Add API doc for clarification
    - Add methods:
       - ArrayList<GLContext> getCreatedShares(final GLContext context)
       - ArrayList<GLContext> getDestroyedShares(final GLContext context)
    - Use 'final' where possible

  - Add GLContext methods:
      - boolean isShared()
      - List<GLContext> getCreatedShares()
      - List<GLContext> getDestroyedShares()

- Add GLSharedContextSetter interface defining setting a shared GLContext
  directly (GLContext) or via a GLAutoDrawable:
  - setSharedContext(GLContext)
  - setSharedAutoDrawable(GLAutoDrawable)

  Both cause initialization/creation of GLAutoDrawable's drawable/context to be postponed,
  if the shared GLContext is not yet created natively or
  the shared GLAutoDrawable's GLContext does not yet exist.

  Most of impl. resides in GLDrawableHelper

  Implemented in:
    - GLAutoDrawableBase, GLOffscreenAutoDrawable
    - GLWindow
    - AWT GLCanvas

  TODO:
    - GLJPanel
    - SWT GLCanvas

- GLDrawableFactory:
   - Add 'GLOffscreenAutoDrawable createOffscreenAutoDrawable(..)' variant w/o passing the
     optional shared GLContext _and_ specifying lazy GLContext
     creation. This allows to benefit from GLSharedContextSetter contract.
     Lazy GLContext creation is performed at 2st display() call at the latest.

     All JOGL code and unit tests use this new method now.

  - Mark 'createOffscreenAutoDrawable(..)' w/ shared GLContext argument
    and immediate GLContext creation deprecated - shall be removed in 2.2.0

- Make reference to GLContext and it's native handle volatile
  Since we rely on the query 'GLContext.isCreated()' to properly allow GLAutoDrawable's to query whether
  a shared GLContext is natively created (already), the handle must be volatile
  since such query and the actual creation may operate on different threads.

+++++

- Add/Refine shared GLContext unit tests demonstrating diff. sharing methods.

  All variants of using shared GLContext:
      com.jogamp.opengl.test.junit.jogl.acore.TestSharedContextVBO*

  Most convenient way to share via setSharedAutoDrawable(GLAutoDrawable):
      com.jogamp.opengl.test.junit.jogl.acore.TestSharedContextVBOES2[NEWT|AWT]3

  AWT use w/ JTabbedPane using setSharedAutoDrawable(GLAutoDrawable):
      com.jogamp.opengl.test.junit.jogl.acore.TestSharedContextWithJTabbedPaneAWT

Subject: Bug 876: BuildComposablePipeline: getGL*() shall not return
 downstream.getGL*() [TraceGL* / DebugGL*] ; Simplify GLContextImpl's set
 Debug/Trace Pipeline

Regression of commit 0002fccdcd6383874b2813dc6bbe3e33f5f00924:
  "Trace/Debug shall utilize downstream identification for isGL*() and getGL*() methods."

  Using the downstream identification commit is right for the isGL*() case,
  however, getGL*() returned the downstream object which makes the caller loosing the pipeline!

  Instead, we shall produce !GEN_GL_IDENTITY_BY_ASSIGNABLE_CLASS:

     "if( isGL<type>() ) { return this; }
     throw new GLException("Not a <type> implementation");"

  or for GEN_GL_IDENTITY_BY_ASSIGNABLE_CLASS:

     "return this;"

Subject: Fix #875 - ES version should be strictly validated

When initializing the context in GLContextImpl.setGLFuncAvailability
ES devices must be validated by strictly matching the major version,
otherwise on ES3 devices we were mixing ES1 implementation with ES3
contexts, ultimately crashing in a safeguard.

Subject: Fix Bug 875 - Cleanup branch using VersionNumber (fix 'Int' check
 strictMatch minor) and reuse isES; EGLContext: Use strictMatch for
 setGLFunctionAvailability() and handle failure; EGLDrawableFactory: Either
 detect ES3 or ES2.

- Cleanup branch using VersionNumber (fix 'Int' check strictMatch minor) and reuse isES

- EGLContext: Use strictMatch for setGLFunctionAvailability() and handle failure
  On ES, we require strictMatch, cleanup if failing.

- EGLDrawableFactory: Either detect ES3 or ES2.
  Both only available with proper EGL context creation for ES profiles (TODO)

Subject: GLRendererQuirks: Add GLSharedContextBuggy ('Mesa Intel 9.2.1' and
 'Hisilicon Immersion.16')

Note: Even though Mesa Intel driver crashes w/ heavy multithreading (Bug 873),
it works well w/ our multithreaded GLMediaPlayer.

From 2dce639c479f820d1a1e701f5eddffc4b02f5e0f Mon Sep 17 00:00:00 2001
From: Sven Gothel <sgothel@jausoft.com>
Date: Thu, 7 Nov 2013 08:36:46 +0100
Subject: Bug 890 - Fix GLES3 Profile Mapping, i.e. GL2ES2 queries and
 mappings; Validate isGLES*() usage and definition ; Add and use
 ShaderCode.createExtensionDirective(..)

- Fix GLES3 Profile Mapping, i.e. GL2ES2 queries and mappings
  - GLProfile: Add GL2ES2 -> ES3 mapping
  - EGLContext: Reuqest major '3' for ES3
  - EGLGLCapabilities/EGLGraphicsConfiguration: Consider EGLExt.EGL_OPENGL_ES3_BIT_KHR

- Validate isGLES*() usage and definition
  - Fix BuildComposablePipeline's isGLES() code

  - For GLSL related queries use isGLES() instead of isGLES2(),
    which would exclude ES3

- Add and use ShaderCode.createExtensionDirective(..)
  - Supporting creating GLSL extension directives while reusing strings from GLExtensions

- Minor cleanup of GLContextImpl.setGLFuncAvail(..)

Subject: Bug 925 - Accept an ES3 Context, if reported via GL-Version-String
 w/o EGL_OPENGL_ES3_BIT_KHR

Add Quirk 'GLES3ViaEGLES2Config': ES3 Context is used via EGL_OPENGL_ES2_BIT and 'version 2' for create context attributes.

- GLContextImpl.setGLFunctionAvailability(..)'s ES version validation
  only fails if requested major version == 1 and doesn't match.
  Hence requesting major==2 and having version 3 is tolerated.

- GLContextImpl.setGLFunctionAvailability(..)'s Quirks:
    requested-major < has-major -> Adding GLES3ViaEGLES2Config

- EGLDrawableFactory.mapAvailableEGLESConfig(..):
  Reflects has-major version, i.e. GLES3ViaEGLES2Config situation where
  an ES2 request leads to an ES3 version.

Note: All workarounds can be found via lookup of GLES3ViaEGLES2Config (as usual when using quirks).

Subject: Bug 930 - OSX: Using 'Apple Software Renderer' GLRendererQuirks Quirk
 GL4NeedsGL3Request not set

GL3 core version validation failed due to missing braces around 'isES' _and_ term,
where the latter consist out of 2 _or_ terms testing version mismatch.

On OSX we validate a GL3 core context first and expect it to return a GL4 version if available,
which in turn triggers the quirk GL4NeedsGL3Request.
This behavior was disabled due to above mentioned bug, where the unqual major version caused
the validation to fail.

TestGLProfile01NEWT: Fixed 'GL4ES3' test, where 'GL4ES3' is only available
if extension <code>GL_ARB_ES3_compatibility</code> is available as well.

From 7c5483d5b20aed9c87c5ce3f6bc840b6546edcd1 Mon Sep 17 00:00:00 2001
From: Sven Gothel <sgothel@jausoft.com>
Date: Tue, 14 Jan 2014 07:37:26 +0100
Subject: Bug 942 - Share GLBufferStateTracker ; Unify GLBufferStateTracker and
 GLBufferSizeTracker (simplification)

Due to future mapped buffer tracking, the GLBufferStateTracker instance shall be shared
across shared GLContextImpl instances similar to GLSizeStateTracker!

This allows us to merge GLSizeStateTracker code into GLBufferStateTracker
to simplify the implementation.

+++

Clear the GLBufferStateTracker (@destruction) only if no more
created shares are left!

-/**
- * Tracks as closely as possible the sizes of allocated OpenGL buffer
- * objects. When glMapBuffer or glMapBufferARB is called, in order to
- * turn the resulting base address into a java.nio.ByteBuffer, we need
- * to know the size in bytes of the allocated OpenGL buffer object.
- * Previously we would compute this size by using
- * glGetBufferParameterivARB with a pname of GL_BUFFER_SIZE, but
- * it appears doing so each time glMapBuffer is called is too costly
- * on at least Apple's new multithreaded OpenGL implementation. <P>
- *
- * Instead we now try to track the sizes of allocated buffer objects.
- * We watch calls to glBindBuffer to see which buffer is bound to
- * which target and to glBufferData to see how large the buffer's
- * allocated size is. When glMapBuffer is called, we consult our table
- * of buffer sizes to see if we can return an answer without a glGet
- * call. <P>
- *
- * We share the GLBufferSizeTracker objects among all GLContexts for
- * which sharing is enabled, because the namespace for buffer objects
- * is the same for these contexts. <P>
- *
- * Tracking the state of which buffer objects are bound is done in the
- * GLBufferStateTracker and is not completely trivial. In the face of
- * calls to glPushClientAttrib / glPopClientAttrib we currently punt
- * and re-fetch the bound buffer object for the state in question;
- * see, for example, glVertexPointer and the calls down to
- * GLBufferStateTracker.getBoundBufferObject(). Note that we currently
- * ignore new binding targets such as GL_TRANSFORM_FEEDBACK_BUFFER_NV;
- * the fact that new binding targets may be added in the future makes
- * it impossible to cache state for these new targets. <P>
- *
- * Ignoring new binding targets, the primary situation in which we may
- * not be able to return a cached answer is in the case of an error,
- * where glBindBuffer may not have been called before trying to call
- * glBufferData. Also, if external native code modifies a buffer
- * object, we may return an incorrect answer. (FIXME: this case
- * requires more thought, and perhaps stochastic and
- * exponential-fallback checking. However, note that it can only occur
- * in the face of external native code which requires that the
- * application be signed anyway, so there is no security risk in this

Subject: Bug 942: Bug 942 - Review GLBuffer[State|Size]Tracker and NIO mapped
 buffers

Commit f8a74c9831c65725a699320c27e62161a0378241 reverted
commit 7c5483d5b20aed9c87c5ce3f6bc840b6546edcd1
due to the fact that the buffer binding itself is _not_
shared across shared GLContext!

Apply uncritical changes of 7c5483d5b20aed9c87c5ce3f6bc840b6546edcd1:

+++

Simplify GLBufferSizeTracker creation @ GLContextImpl ctor,
make it final.

+++

Clear the GLBufferSizeTracker (@destruction) only if no more
created shares are left!

+++

Refine API doc.

From 09fc7aa5539731bb0fba835caee61f6eb837ecff Mon Sep 17 00:00:00 2001
From: Sven Gothel <sgothel@jausoft.com>

Subject: Bug 942: GLBufferObjectTracker: Tracking GLBufferStorage accurately,
 synchronized and secure [1/2]

GLBufferSizeTracker becomes GLBufferObjectTracker
and tracks the buffer's data store, GLBufferStorage, accurately, synchronized and secure.

Synchronization is required, since the GLBufferStorage can be
shared across many GLContext on multiple threads.

This requires all GLBufferStorage lifecycle affecting GL functions
to utilize synchronized GLBufferObjectTracker methods
while passing a native GL-func callback.

These GL functions are:
  - glBufferData, glBufferStorage (GL 4.4), glNamedBufferDataEXT
    Creating the GLBufferStorage object
  - glMapBuffer, glMapBufferRange, and their *Named*EXT variants
  - glUnmapBuffer, glUnmapNamedBufferEXT

'glDeleteBuffers' can simply notify the GLBufferObjectTracker

No more HashMap is required to associate the mapped buffer address
to the mapped ByteBuffer.

GLBufferObjectTracker simply utilizes a
   buffer-name (int) -> GLBufferStorage
map.

+++

The security aspect shall be implemented by validating all arguments
whether they match the required GL constraints,
as well as validating tracked states like 'size'.

The following functions will throw an GLException accordingly:
  - glBufferData, glNamedBufferDataEXT
     * @throws GLException if size is less-than zero
     * @throws GLException if a native GL-Error occurs

  - glBufferStorage (GL 4.4)
     * @throws GLException if size is less-or-eqaul zero
     * @throws GLException if a native GL-Error occurs

  - glMapBuffer, and it's *Named*EXT variant
    * @throws GLException if buffer is not bound to target
    * @throws GLException if buffer is not tracked
    * @throws GLException if buffer is already mapped
    * @throws GLException if buffer has invalid store size, i.e. less-than zero

  - glMapBufferRange, and it's *Named*EXT variant
    * @throws GLException if buffer is not bound to target
    * @throws GLException if buffer is not tracked
    * @throws GLException if buffer is already mapped
    * @throws GLException if buffer has invalid store size, i.e. less-than zero
    * @throws GLException if buffer mapping range does not fit, incl. offset

  - glMapBufferRange, and it's *Named*EXT variant
    Only clear mapped buffer reference of GLBufferStorage
    if native unmap was successful.

Further more special error handling shall be applied to:
  - glMapBuffer, and it's *Named*EXT variant,
    glMapBuffer, and it's *Named*EXT variant
    - A zero GLBufferStorage size will avoid a native call and
      returns null
    - A null native mapping result indicating an error will
     not cause a GLException but returns null
     This allows the user to handle this case.

+/**
+ * Tracking of {@link GLBufferStorage} instances via GL API callbacks.
+ * <p>
+ * See {@link GLBufferStorage} for generic details.
+ * </p>
+ * <p>
+ * Buffer storage is created via
+ * <ul>
+ *   <li><code>glBufferStorage</code> - storage creation with target via {@link #createBufferStorage(GLBufferStateTracker, GL, int, long, Buffer, int, int, CreateStorageDispatch, long)}</li>
+ *   <li>{@link GL#glBufferData(int, long, java.nio.Buffer, int)} - storage recreation with target via {@link #createBufferStorage(GLBufferStateTracker, GL, int, long, Buffer, int, int, CreateStorageDispatch, long)}</li>
+ *   <li>{@link GL2#glNamedBufferDataEXT(int, long, java.nio.Buffer, int)} - storage recreation, direct, via {@link #createBufferStorage(GL, int, long, Buffer, int, CreateStorageDispatch, long)}</li>
+ * </ul>
+ * Note that storage <i>recreation</i> as mentioned above also invalidate a previous storage instance,
+ * i.e. disposed the buffer's current storage if exist and attaches a new storage instance.
+ * </p>
+ * <p>
+ * Buffers storage is disposed via
+ * <ul>
+ *   <li>{@link GL#glDeleteBuffers(int, IntBuffer)} - explicit, direct, via {@link #notifyBuffersDeleted(int, IntBuffer)} or {@link #notifyBuffersDeleted(int, int[], int)}</li>
+ *   <li>{@link GL#glBufferData(int, long, java.nio.Buffer, int)} - storage recreation via target</li>
+ *   <li>{@link GL2#glNamedBufferDataEXT(int, long, java.nio.Buffer, int)} - storage recreation, direct</li>
+ * </ul>
+ * </p>
+ *
+ * <p>
+ * Implementation throws a {@link GLException} in all <i>construction</i> methods as listed below,
+ * if GL-function constraints are not met. <code>createBufferStorage</code> also throws an exception
+ * if the native GL-function fails.
+ * <ul>
+ *   <li>{@link #createBufferStorage(GLBufferStateTracker, GL, int, long, Buffer, int, int, CreateStorageDispatch, long)}, etc ..</li>
+ *   <li>{@link #mapBuffer(GLBufferStateTracker, GL, int, int, MapBufferAllDispatch, long)}, etc ..</li>
+ * </ul>
+ * In <i>destruction</i> and informal methods, i.e. all others, implementation only issues a WARNING debug message, if enabled.
+ * </p>
+ *
+ * <p>
+ * Buffer mapping methods like {@link GL#mapBuffer(int, int)} ...,
+ * require knowledge of the buffer's storage size as determined via it's creation with
+ * {@link GL#glBufferData(int, long, java.nio.Buffer, int)} ....
+ * </p>
+ * <p>
+ * Hence we track the OpenGL buffer's {@link GLBufferStorage} to be able to
+ * access the buffer's storage size. The tracked {@link GLBufferStorage} instances
+ * also allow users to conveniently access details of their created and maybe mapped buffer storage.
+ * </p>
+ * <p>
+ * The {@link GLBufferObjectTracker} and it's tracked {@link GLBufferStorage} instances
+ * maybe shared across multiple OpenGL context, hence this class is thread safe and employs synchronization.
+ * </p>
+ * <p>
+ * Implementation requires and utilizes a local {@link GLBufferStateTracker}
+ * to resolve the actual buffer-name bound to the given target.
+ * </p>
+ * <p>
+ * Note: This tracker requires to be notified about all OpenGL buffer storage operations,
+ * as well as the local {@link GLBufferStateTracker} to be notified about all
+ * OpenGL buffer binding operations.
+ * Hence buffer storage cannot be accessed properly if managed via native code.

-/**
- * Tracks as closely as possible the sizes of allocated OpenGL buffer
- * objects.
- * <p>
- * <code>glMapBuffer</code> or <code>glMapBufferRange</code> etc
- * returns a <code>java.nio.ByteBuffer</code>
- * instance reflecting the returned native address of respective calls
- * and the actual buffer size.
- * </p>
- * <p>
- * In case the buffer size is unknown, we need to compute this size by using
- * <code>glGetBufferParameteriv</code> with a pname of <code>GL_BUFFER_SIZE</code>.
- * The latter appears to be problematic due to the returned <code>int</code> value,
- * where size should be of type <code>long</code>.
- * Further more, this query appears to be costly for each glMapBuffer call
- * at for Apple's new multithreaded OpenGL implementation.
- * </p>
- * <p>
- * The buffer size state is shared across all shared OpenGL context,
- * hence we share the GLBufferSizeTracker instance across all shared GLContexts.
- * Hence utilizing this instance must be synchronized to be thread safe due to multithreading usage.
- * </p>
- * <p>
- * We track the sizes of allocated buffer objects.
- * We track calls to <code>glBindBuffer</code> etc to see which buffer is bound to
- * which target and to <code>glBufferData</code> to see how large the buffer's
- * allocated size is. When <code>glMapBuffer</code> is called, we consult our table
- * of buffer sizes to see if we can return an answer without a glGet
- * call.
- * </p>
- * <p>
- * In the face of calls to glPushClientAttrib / glPopClientAttrib we currently punt
- * and re-fetch the bound buffer object for the state in question;
- * see, for example, <code>glVertexPointer</code> and the calls down to
- * <code>GLBufferStateTracker.getBoundBufferObject()</code>. Note that we currently
- * ignore new binding targets such as <code>GL_TRANSFORM_FEEDBACK_BUFFER_NV</code>;
- * the fact that new binding targets may be added in the future makes
- * it impossible to cache state for these new targets.
- * </p>
- * <p>
- * Ignoring new binding targets, the primary situation in which we may
- * not be able to return a cached answer is in the case of an error,
- * where <code>glBindBuffer</code> may not have been called before trying to call
- * <code>glBufferData</code>. Also, if external native code modifies a buffer
- * object, we may return an incorrect answer. (FIXME: this case
- * requires more thought, and perhaps stochastic and
- * exponential-fallback checking. However, note that it can only occur
- * in the face of external native code which requires that the
- * application be signed anyway, so there is no security risk in this
- * area.)
- * </p>

Subject: Bug 950 - Recognize full FBO capabilities for ES 3.0 -
 [GLContext|GL].hasFullFBOSupport() == true

OpenGL ES 3.0 supports full framebuffer operations, incl. multiple color-attachments and multisample.

Hence [GLContext|GL].hasFullFBOSupport()  shall returns true w/ a ES 3.0 context.

Subject: Bug 948 - NVIDIA 331.38 (Linux X11) EGL impl. only supports _one_ EGL
 Display via eglGetDisplay(..)

NVIDIA 331.38 (Linux X11) EGL impl. only supports _one_ EGL Display via eglGetDisplay.

  - Subsequent eglGetDisplay(..) calls fail.

  - Using the same 'global' egl-display does work though

Remedy: Add 'GLRendererQuirks.SingletonEGLDisplayOnly'

Detection of quirk is done as usual in GLContextImpl.setRendererQuirks(..),
and EGLDrawableFactory passes the quirk, if detected, down to EGLDisplayUtil.
The latter implements the singleton eglDisplay handle.

EGLDisplayUtil: Cleaned up ..
  - EGLDisplayRef employs the reference handling incl. eglInitialize(..) and eglTerminate(),
    as well as the new singleton quirk.

  - Mark all internal methods 'private',
    to remove possible [untested] sideffects.

Subject: Bug 948 - Autodetect GLRendererQuirks.SingletonEGLDisplayOnly

Refines commit fbe00e6f5dca8043b40dd96f096fecc9424e0cc3

Instead of querying driver artifacts (vendor, platform, version ..)
we simply can autodetect this quirk by trying to get a second egl-display handle
when initializing the EGLDrawablFactory's default device:
  EGL.eglGetDisplay(EGL.EGL_DEFAULT_DISPLAY)

Subject: Bug 972 - Reduce ClassLoader Lookup, i.e. Class.forName(..):
 GLProfile, GLContextImpl, DisplayImpl

GLProfile, GLContextImpl:
  - ReflectionUtil.DEBUG_STATS_FORNAME: Dump forName stats if set
  - Cache GL*Impl and GL*ProcAddressTable Constructor<?> for GLContextImpl's createInstance(..)
  - Remove off-thread early classloading thread which only adds complications

DisplayImpl:
  - Remove one redundant availability test
