Read Drawable feature reflects the make context current API
having a seperate read drawable next to the write drawable (default).
glXMakeContextCurrent(write, read, ..)
On X11 a ready drawable is only supported for GLX >= 1.3,
on Windows only if extension WGL_ARB_make_current_read is available,
on EGL it's always supported, on OSX not at all.
API cleanup GLContext:
changes: setGLDrawableRead(GLDrawable) -> setGLReadDrawable(GLDrawable)
new: isGLReadDrawableAvailable()
new: getGLExtensionsString();
Access qualifier cleanup.
GLContextImpl: GLVersionNumber moved out.

fail-fast hash cache, ..
Relates to GlueGen 6b6b9b3b81cdc85b7260664ebec547756a6be5d7, branch sgothel_wip_fixes01.
Memory object size is ptrdiff_t, hence long (64bit).
The hash value must include size as well, otherwise boundaries cannot be verified. (security)
Double check hash collisions while adding a new MemoryObject.

Reduce (performance/footprint) overhead of ProcAddressTable recreation,
instead use a hashmap (major, minor, profile) -> ProcAddressTable.
Remove GL2ES12 implementation profile, redundant.

Changed GLProfile/NativeWindowFactory/.. initialization methodology:
GLProfile:
public static synchronized void initSingleton(final boolean firstUIActionOnProcess);
NativeWindowFactory:
public static synchronized void initSingleton(final boolean firstUIActionOnProcess);
+++
Introducing NativeWindow ToolkitLock, implementations are
NullToolkitLock
JAWTToolkitLock
X11JAWTToolkitLock
X11ToolkitLock
AbstractGraphicsDevice provides generic global toolkit locking methods,
implemented by the ToolkitLock interface.
ToolkitLock's are aggregated in NativeWindow's DefaultGraphicsDevice
to implement it's superclass lock()/unlock() methods.
This enables a device specific locking strategy, ie on X11/AWT utilizing
JAWT && X11 locking, and maybe none for others (NEWT).
No locking is required for X11 / AWT, in case the above mentioned
initialization happened as a 'firstUIActionOnProcess'.
The ToolkitLock factory is currently a hardcoded part of NativeWindowFactory.
We may have to allow 3rd party NativeWindow implementations
to register custom ones.
+++
com.jogamp.opengl.impl.GLDrawableImpl cleanup:
Dealing with all locking code, providing all public methods. Exceptions are commented.
Specializations x11/windows/.. only contains platform code.
Pulled down access qualifiers if possible public -> protected.
com.jogamp.nativewindow.impl.x11.X11Util
Wrapping all X11Lib method with the new locking code.
com.jogamp.nativewindow.impl.jawt.JAWTUtil
Utilize global SunToolkit.awtLock() is available,
the fallback to global JAWT.lock().
The latter just invokes the first.
javax.media.nativewindow.awt.AWTGraphicsDevice
setHandle(long handle) -> setSubType(String type, long handle)
which also resets the ToolkitLock respecting the new type.
This ensures correct locking after the sub type has been determined,
ie AWT using an X11 peer.
+++
Misc Changes done on the way ..
GLCanvas:
Fixed inversed this.drawableHelper.isExternalAnimatorAnimating() condition,
which disabled normal repaint.
GLJPanel:
Removed drawableHelper.isExternalAnimatorAnimating() condition,
which disabled painting, since the animation thread just updates the source image.
NEWT WindowImpl:
When reparenting back to parent and 'refit' child if it's size exceeds it's parent.
More 'Fix: Memory consumption' commit 6ced17f0325d5719e992b246ffd156e5b39694b4.
NEWTEvent:
Removed code to evaluate the 'system event' attribute, need to find a better approach.

- Update header:
- GL/glext.h to khronos 2010-08-03
- GL3/gl3.h to khronos 2010-08-03
- Move platform code to
GL/glplatform.h
GL3/glplatform.h
- Unify 64bit typedefs: gl-64bit-types.h
- Move GL 3.[123] and 4.[01] complete subsumed extension
enums and functions into their extension spec and just reference them.
This ensures proper extension availability
via lower OpenGL profiles, hence a proper GL2GL3 interface.
- GL3/GL4 cleanup:
- make-glextension-depignore.sh:
determine required GL version for extensions
for proper positioning, ie GL2GL3 or GL3 or GL4
via gluegen IgnoreExtension commands.
- use ARB_ES2_compatibility for common GL2ES2 methods,
if available
- consolidated gl2-gl4 subsumed extension to gl-common.cfg
- Missing GL3/GL4 Functions:
glMultiDrawElementsBaseVertex
glDebugMessageCallbackARB
glDebugMessageCallbackAMD
- TODO (new feature integration):
- ARB_ES2_compatibility / ARB_get_program_binary for com/jogamp/opengl/util/glsl, ie
- store binaries com/jogamp/opengl/util/glsl/sdk/CompileShader*
- query supported binary formats (enums ?)
- optional prio binaries
- ARB_ES2_compatibility, if available GLES2/GL2ES12 would be available
- ARB_separate_shader_objects for com/jogamp/opengl/util/glsl, ie
- swizzle vertex/fragment shader in programs
- ..

glMap*Buffer*; GLX/WGL/CgGL: All runtime dynamic; Misc ..
TODO: Compile and test on MacOSX ..
Fix:
=====
Multithreading/Locking:
See jogl/doc/Implementation/MultiThreading.txt
- Locking layer is not platform agnostic, ie GLContextImpl, GLDrawableImpl, ..
and NEWT: Window/Display
- No more use of JAWT global lock necessary, removed.
- No need for X11 Display lock, on the contrary,
this made the NV driver hang.
- Use common window/surface lock
- All NativeWindow surfaceLock's are recursive now
glMapBuffer: If size is 0, don't do cont with the native call.
glMapBufferRange: Fix capacity.
glNamedBufferDataEXT: Track the size.
glMapNamedBufferEXT: Manual impl. - use the tracked size
glXGetVisualFromFBConfig, glXChooseFBConfig, glXChooseVisual: Instead of
ignoring and implement a renamed version (*Copied), we just use ManualImplementation
for the proper copy-result code.
DesktopGLDynamicLookupHelper: Initialize _hasGLBinding* attributes
in the determing loadGLJNILibrary() method, which is called by super().
Otherwise static init will overwrite them after the super() call.
X11GLXDrawableFactory: Don't release anything at shutdown (removed sharedContext.destroy()),
since this caused a freeze/SEGV sometimes.
Fixed NEWT's reparentWindow() functionality incl NewtCanvasAWT usage.
- Native: if not visible, don't focus, etc
- NewtCanvasAWT: Use the container size to start with
- Run the command on the EDT
Using GlueGen's new DynamicLibraryBundle utility:
- X11, Windows and MacOSX OpenGL adapted to DynamicLibraryBundleInfo.
- X11GLXDynamicLookupHelper -> X11GLXDynamicLibraryBundleInfo
- Remove all path from lib names.
- GL order: libGL.so.1, libGL.so, GL
- shallLinkGlobal: true -> to server some 'old' DRI systems
-> http://dri.sourceforge.net/doc/DRIuserguide.html
- shallLookupGlobal: false
- Try both : glXGetProcAddressARB and glXGetProcAddress
- Using bootstrap: GLX.glXGetProcAddress(long glxGetProcAddressHandle, String glFuncName)
Found the issue with LIBGL_DRIVERS_PATH, ie if not set
no valid GL instance can be found (ie ATI fglrx/DRI).
This may happen if using a differen user than the desktop user
for whom the env var is set within some /etc/X11/Xsession.d/ script.
Enhancements:
=============
GLBufferSizeTracker: Use IntIntHashMap and add DirectState size tracking.
GLBufferStateTracker: Use IntIntHashMap.
GLStateTracker: Use IntIntHashMap.
GLDynamicLookupHelper: More generic (global loading/lookup and GetProcAddress function name list),
remove redundant code.
FIXME:
MacOSXCGLDynamicLookupHelper:
- Not tested
- Not using NSImage lookup anymore as recommended by OSX API Doc,
so dlsym is used always (to be tested)
WindowsWGLDynamicLookupHelper:
- Not tested
GLX/WGL/CgGL is all runtime-dynamic as now, ie loaded and looked-up at runtime,
no compile time dependencies to GL anymore, nor a need to specify CgGL.
Split up WGL in GDI and WGL, to allow proper dynamic runtime linkage of OpenGL32
while using static binding to GDI32
NEWT events generated by native code are enqueued and not send directly.
This should ease locking mechanisms .. if any are necessary.
NEWT: More platform specific code moved to *Impl method,
simplifying the generic code of the superclass and impl protocol.
Cleanup:
=========
Replace all InternalBufferUtil's with com.jogamp.common.nio.Buffers
Removed all InternalBufferUtil's from repository
Removed GLContextImpl notion of 'optimized' surface locking,
where the surface gets unlocked during makeCurrent/release.
This just makes no sense and would impact multithreading in a horrible way.

GLAutoDrawable: dispose() calls only with created context.
- Using the EGL approach of DynamicLookupHelper,
now generalized in abstract GLDynamicLookupHelper,
DesktopGLDynamicLookupHelper and EGLGLDynamicLookupHelper.
The implementation of these are self contained.
- Sharing common code.
- Unifying implementation and binding loading,
as well as the function lookup within the impl libs.
- Removed DRIHack, since its no more required
due to the new DesktopGLDynamicLookupHelper.
- Removed compile time link to GL and GLU libs
- Removed redundant library OS functions from X11/WGL
bindings, GlueGen's common code is being used now.
- GLAutoDrawable: dispose() calls only with created context.
This cleans up stack traces in case of eventual bugs,
where context creation is not successful.

- Restructure: JAWT gluegen, use common jawt-common.cfg
- Fix: Use proper capacity for GetDrawingSurface and GetDrawingSurfaceInfo
- Fix: JAWTWindow maintains AWT bounds
- Fix: JAWTWindow locking/unlocking decoupled with abstract implementation,
which allows clear code and simpler unlock code.

+++++
Changed NEWT NativeWindow creation contract
Original contract:
(1) A native window was created as soon as possible,
ie when NEWTFactory.createWindow(..) was called - if possible.
(2) A valid native window has to be created at least after setVisible(true)
has been called.
Problems:
Not all implementation are able to create the native window that early,
but at setVisible(true) only (e.g: KD and EGL).
Due to window parenting especially the new AWT/NEWT parenting,
the native window can only be created in case the parent native window is valid.
New contract:
(1) A native window is created at setVisible(true),
if it's a top level window or the native parent window is valid.
(2) A valid native window may not be created after setVisible(true)
has been called.
Subsequent setVisible(true) calls shall be made in case
the creation has not been done yet.
This is demonstrated in GLWindow.display() for example.
The new contract implements a lazy native window creation.
+++++
AWT/NEWT Parenting
- HierarchyListener and ComponentListener ensure that the NEWT child window
will be setVisible according to the AWT parent window.
- Lazy native window creation relaxes requirements to the parent window's state.
- Attachment of the child window and setVisible() may be called
after NEWT child window creation.
- GLWindow supports NEWT child window creation directly
The test case TestParenting01AWT.java reflect this new contract
and demonstrates more simplified and more flexible use cases.
+++++
NEWT Fixes:
- All NEWT implementation's native code method names end with 0.
- GLWindow: don't issue the actual 'init'/'display' call to GLEventListeners
in case the window is not visible.
- NEWT setSize/setPosition:
if native-window
call native-window action and let the attributes being set by
the feedback call, which issues more action, ie RESIZE.
else
set the attributes directly, no feedback call/action is necessary.
+++++
X11 Fixes:
- X11GLContext MakeContextCurrent:
Use MakeCurrent in case write and read drawable are equal,
otherwise SEGV happens on ATI with heavy multithreading involved!
Even XLockDisplay and XSync didn't help here ..
- X11GLXDrawableFactory shared resource:
Removed the resource holder thread to simplify code,
hence proper release is no more desired and it could become a cause for deadlock.
- Moved XInitThreads() from NEWT X11Window -> NativeWindow X11Util,
since NativeWindow is loaded first (essential for XInitThreads())
and it is the more basic lib.
- Made call to XInitThreads() conditional, ie it's spared if
AWT could be used - which causes SEGV .. (AWT bug). See X11Util.java
+++++
JOGL Fixes:
- GLProfile.isAWTAvailable() -> NativeWindowFactory.isAWTAvailable()
- GLProfile.isAWTJOGLAvailable() -> GLProfile.isAWTAvailable()

- X11GLXDrawableFactory:
- Move shared resource creation/destruction into it's own thread
- Remove the ATI hack (no XDisplay closing) for every Display,
this is only necessary for the shared XDisplay and in case of AWT.
- Newt
- Display: Only pumpMessages if device is ready.
- X11Display: Verify handle not null at DispatchMessage.
- Common recursive ToolkitLock implementation, from
src/nativewindow/classes/com/jogamp/nativewindow/impl/LockingNativeWindowFactory.java and
src/newt/classes/com/jogamp/newt/Window.java,
-> com.jogamp.nativewindow.impl.RecursiveToolkitLock
- Unique XLockDisplay/XUnlockDisplay call via X11Util to simplify debugging.
X11Util: Added debug code for XLockDisplay/XUnlockDisplay.
Added fast LongObjectHashMap
Added static lib loading and initialization.
Removed active and passive list, as well as unused methods,
to easy maintenance. Possible since the only 'uncloseable' Display
might be the shareable one.
- X11Lib: Added static initialization via X11Util
Test:
junit/com/jogamp/test/junit/jogl/demos/gl2/gears/TestGears*
- Add WindowListener for quit ..

- All available OpenGL versions (native/platform) are verified at GLProfile
initialization and can be queried ..
A mapping of major,compat -> major,minor,options is created.
- Removal of temp context creation, when creating a context.
This was necessary to query general availability of ARB_create_context.
Due to the shared context of X11GLXDrawableFactory and WindowsWGLDrawableFactory,
this is no more necessary.
Due to the version mapping, the ARB_create_context paramters are known.
- NativeWindow X11Lib: Added X11ErrorHandler, throwing a RuntimeException.
Necessary to catch BadMatch .. etc X11 errors, eg for glXCreateContextAttribsARB
Hence all X11 calls are covered now.
- X11DummyGLXDrawable needs to use an own Window, otherwise GLn n>2 fails
- Flattening the desktop GL* implementation,
all use GL4bcImpl, which reduces the footprint dramatically.
- GL*Impl.isGL*() (desktop) utilizes the GLContext.isGL*(),
hence the results reflect the actual native context version.
- GLContextImpl makeCurrent/create: Added workflow documentation,
clarified code, defined abstract methods to have a protocol.
- Removed moved files (from here to gluegen),
see gluegen a01cb3d59715a41153380f1977ec75263b762dc6
- NativeLibLoader -> <TYPE>JNILibLoader
- Fixed Exception Handling (as in gluegen bce53b52c8638729750c4286dbc04cb14329fd34),
ie removed empty catch Throwable ..
- GLContext.setSwapInterval(): Nop in offscreen case, otherwise X11IOError (NVIDIA Bug)
Test:
Tests
- Junit
- demos.gears.Gears
- demos.jrefract.JRefract
Platforms
- Linux 64/32 ATI/NVidia
- MacOsX
- Windows (virtualbox 3.1.6, offscreen failed)
TODO/BUGS:
- FIXME ATI GLn n>2 with AWT, can't make context current, works well on NVIDIA though
- FIXME GL3GL4: Due to GL3 and GL4 implementation bugs, we still choose GL2 first, if available!
- Add GL 3.3 to GL3/gl3ext.h
- Add GL 4.0 to GL3/gl3ext.h and fix the GL3/GL4 seperation
- Rename jogl.gl2.jar -> jogl.gldesktop.jar (as done with it's native lib already)

- Re-Enable GL3bc native library build, works ..
- Adding all the is/get GL4/GL4bc stubs ..
- Adding dummy interface GL4 and GL4bc, will be removed when done
- Context creation refactoring:
- Move Version information to GLContext
- Determine version by creation if possible (ARB_create_context),
only use the unreliable GL_VERSION string if necessary.
- Offering an almost platform independent ARB_create_context path:
- createContextARBImpl - platform dependent GLX calls
- createContextARB - platform independent setup and version loop

- See https://bugzilla.mozilla.org/show_bug.cgi?id=486277
- Calling XCloseDisplay occasionally leads to a SIGSEGV,
even thought the reference is valid and OK.
Workaround is not to close any X11Display,
but to hold them stashed and reuse them.
Since we already pipeline all X11Display's
via Nativewindow's X11Util, an added referenceCounter
and a global active/passive list solved this problem.
This workaround is only active in case 'isVendorATI()'.
NEWT/NativeWindow X11:
- Let XIOErrorHandler and invalid display references
fail hard with FatalError, otherwise we won't see
the stack trace - and those bugs are indeed fatal.
NativeWindow X11:
- Install XIOErrorHandler, which stays active.
- X11Util.X11Display:
- Add reference counter
- Add global active/passive list.
Passive if reference count == 0
and marked as 'un-closeable' (-> ATI).
Reusing passive members when create a new display.
-
JOGL:
- Use DeleteLocalRef() calls to free temp NIO buffer
in manual *Copied implementation.
- GLDrawableFactoryImpl: Be serious about the shutdown() semantics
- *GraphicsConfiguration:
- Fix the invalid Onscreen/PBuffer/Pixmap determination (X11/EGL/WGL)
- Just return null if not valid
- X11GLXGraphicsConfigurationFactory - FBConfig
- Determine recommendedIndex properly ..
- Don't bail out if a FBConfig is invalid ..
- Use Chooser in case nothing is recommended ..
- X11OffscreenGLXDrawable fixes bugs:
- wrong (int) cast of parent window in XCreatePixmap call
- setting display to zero too early in destruction, ie
before XCloseDisplay
- X11GLXDrawableFactory is using [singleton] shared dummy resources for
- Screen, Drawable and Context
which are utilized in case they are needed ..
They are removed at shutdown call
- GLXVersion gathering in GLXUtil now ..
- DefaultGLCapabilitiesChooser: Respect PBuffer selection
Tests:
- Add DrawableFactory shutdown()
- Add various Offscreen Capabilties
- Add Offscreen and non-pbuffer case
- JUnit Passed (Linux64bit: NVidia/ATI)
- demos.jrefract.JRefract passed (Linux64bit: NVidia/ATI)

- See https://bugzilla.mozilla.org/show_bug.cgi?id=486277
- Description:
- To use PBuffer, a context must be current
- X11Display cannot be switched while using the PBuffer
[within one thread]. Hence we shall try harder to reuse
_the_ user configured X11Display - whenever possible.
This is actually a good thing, ie cleanup up our
code again.
- Changes to workaround/cleanup:
- GLDrawableFactory* methods 'canCreate*()'
are changed to 'canCreate*(AbstractGraphicsDevice)'
to allow pipelining the X11Display.
This reduces the overhead of using a local TLS X11Display.
- WindowsDummyWGLDrawable cstr gets the GLProfile as a parameter now,
this is done while adding X11DummyGLXDrawable - forseeing the
usecase to query available GLProfiles at startup.
- X11DummyGLXDrawable added, following the WindowsDummyWGLDrawable path
to have a dummy GLContext current to fix the ATI bug.
NativeWindow X11:
- Add XIOErrorHandler to identify the fatal failure
of closing a Display (-> ATI bug).
Build:
- Adding ant.jar and ant-junit.jar to the junit compile/run classpath
-
Misc:
- Fix: CreateDummyWindow(..) returns a HWND, not a HDC
- mapToRealGLFunctionName: Added mapping for X11/GLX.
- X11GLXGraphicsConfigurationFactory: Uncommented dead code 'createDefaultGraphicsConfigurationFBConfig'
Tests: Passed (Linux64bit: NVidia/ATI)
Todo: More tests on ATI, especially multithreading/X11Display usage.

where 'bc' is not a religious remark,
but simply means 'backward compatible' :)
GL3bc := GL2 + GL3,
hence the interface does not define any new values or methods.
Moved GL3's 3.1 part from gl3.h to gl3ext.h,
so it can be included in gl3bc.c, besides gl2.h.

Premises:
See http://www.glprogramming.com/red/chapter08.html
"If the rectangle in memory is larger than the subrectangle that's being drawn or read,
you need to specify the actual length (measured in pixels) of the larger rectangle with *ROW_LENGTH. "
This equals ROW_LENGTH == SubPicture-Width + 'Dirt', ie the offset to go from one line to the next.
"You also need to specify the number of rows and pixels to skip before starting to copy the data for the subrectangle.
These numbers are set using the parameters *SKIP_ROWS and *SKIP_PIXELS, as shown in Figure 8-9.
By default, both parameters are 0, so you start at the lower-left corner."
This equals to a one time offset _before_ you start copy the data, ie with your DMA engine,
using ROW_LENGTH and HEIGHT only.
Compared to Mesa3D's implementation (proof):
http://cgit.freedesktop.org/mesa/mesa/tree/src/glx/x11/pixelstore.c
Line 78 - 200
PixelStore State Tracker: Store the values in the PixelStore structure.
http://cgit.freedesktop.org/mesa/mesa/tree/src/glx/x11/pixel.c
Line 82 - 155
Line 210: Start position is set one time using SKIP_* values the same way we do.
Line 228: Jump to the first pixel in the newxt row, just using ROW_LENGTH
Line 230: Jump to the first pixel in the next 'image' just using imageSize,
rowsPerImage = IMAGE_HEIGHT>0?IMAGE_HEIGHT:height;
groupsPerRow = ROW_LENGTH>0?ROW_LENGTH:width;
groupSize = elementSize * components;
rowSize = groupsPerRow * groupSize;
imageSize = rowSize * rowsPerImage;
changes:
Removed redundand 'dimension' parameted, which is derived from depth and height,
1D == depth:1 height:1
2D == depth:1 height>1
nD == depth>1 height>1
Safe fail depth to >= 1
Safe fail height to >= 1D
Take either the ROW_LENGTH / IMAGE_HEIGHT PixelStore value if > 0,
or the given width / height.

and used within the GL*Impl.
New GLStateTracker:
- Tracking client/server states
- Currently supports PixelStorei
- Prologued in glPixelStorei and glGetIntegerv,
the latter will return the tracked state if available
and not call the GL method.
Impacts performance and ES1 compatibility (supports ALIGNMENT).
Fixed 'imageSizeInBytes' calculation:
- skipPixels and skipRows is a static one time offset

- Fixes for OpenGL 3.2
- More strict define/function checking
- Better documentation in source code: extension relation
- GL extension marker exclusion is done by GlueGen now
- Adapted gluegen cfg files
Added OpenGL 3.2 extensions for GL3
Revalidation of all OpenGL 2.0/3.0/3.1 and 3.2 extensions
GL2GL3 based on OpenGL 2.0/3.0 headers
EGL shares common egl-common.cfg file
Removed experimental java system property 'jogl.GLContext.3_2',
try a 3.2 context in case of GL3.
X11GLXContext:
- Always try to make a created context current,
to verify it's usability. This is different than under WGL.
- Temporary removed usage: GLX.GLX_CONTEXT_PROFILE_MASK_ARB
NV driver bug.
