for a Colorbuffer, also make DEPTH optional.
API Change
+++
In certain cases a TextureAttachment for the FBO's color buffer
is not desired, either for performance reasons where texture functionality
is not required or to avoid texture restrictions like size, etc.
+++
GLFBODrawable shall use TextureAttachment for the FBO's color buffer
and a DEPTH buffer per default.
However, the user shall be allowed to use a plain ColorAttachment (renderbuffer)
and also no DEPTH buffer.
+++
FBObject Details:
- Colorbuffer interface exposes Attachment details
like format, size, etc as well as it's implementation
specifics, isTextureAttachment() and getTextureAttachment() allowing a clean cast and type query.
- Allow ColorAttachment to be used for non MSAA
- Make TextureAttachment optional for method 'use(GL, TextureAttachment)'
- Only validate size against MAX_TEXTURESIZE if using a TextureAttachment
- API Change:
- rename: getColorAttachmentCount() -> getColorbufferCount()
- add: getTextureAttachmentCount()
- change 'TextureAttachment getSamplingSink()' -> 'Colorbuffer getSamplingSink()'

display/screen of a NativeSurface
Currently GLDrawableFactoryImpl's gamma settings are performed
only on the main screen.
Allow passing a NativeSurface, so it's display/screen
gamma values will be changed.
Further, promote low-level gamma settings to GLDrawableFactory
for direct usage.
Change com.jogamp.opengl.util.Gamma to use a GLDrawable
instead of a GL object to clarify that we use the drawable.
Also add a GLAutoDrawable variant, allowing proper locking
of its 'upstream-lock' to guarantee atomicity.
+++
Tested manually w/ TestGearsES2NEWT on X11 and Windows
using the 'g' and 'G' to modify gamma.
Value is properly reset on exit.

crashes the app
The 'magic' MyNSOpenGLContext::dealloc (MacOSXWindowSystemInterface-calayer.m)
of force destroying the underlying CGLContextObj of it's associated
NSOpenGLContext as introduced as a remedy of Bug 691 is plain wrong.
It was added in commit f6e6fab2a7ddfb5c9b614cb072c27ff697629161
to mitigate the experience behavior of delayed GL context
destruction when creating/destroying them multiple times
as exposed in unit test TestGLCanvasAddRemove01SwingAWT.
While this 'hack' worked for some reason on some OSX versions,
it caused a 'access/modify after free' issue exposed under some circumstances
and crashes the application.
The actual culprit of the delayed GL context destruction is different.
The offthread CALayer detachment and hence final destruction
issued on the main-thread is _not_ issued immediately
due to some referencing holding by NSApp.
Issuing an empty event on the NSApp (thread) will wake up the thread
and release claimed resources.
This has been found while realizing that the GL context
are released if the mouse is being moved (duh!).
This issue is also known when triggering stop on the NSApp (NEWT MainThread),
same remedy has been implemented here for a long time.

Add HiDPI for AWT GLCanvas w/ OSX CALayer
Core API Change:
To support HiDPI thoroughly in JOGL (NativeWindow, JOGL, NEWT)
we need to separate window- and pixel units.
NativeWindow and NativeSurface now have distinguished
access methods for window units and pixel units.
NativeWindow: Using window units
- getWindowWidth() * NEW Method *
- getWindowHeight() * NEW Method *
- getX(), getY(), ...
NativeSurface: Using pixel units
- getWidth() -> getSurfaceWidth() * RENAMED *
- getHeight() -> getSurfaceHeight() * RENAMED *
GLDrawable: Using pixel units
- getWidth() -> getSurfaceWidth() * RENAMED, aligned w/ NativeSurface *
- getHeight() -> getSurfaceHeight() * RENAMED, aligned w/ NativeSurface *
Above changes also removes API collision w/ other windowing TK,
e.g. AWT's getWidth()/getHeight() in GLCanvas
and the same method names in GLDrawable before this change.
+++
Now preliminary 'working':
- AWT GLCanvas
- AWT GLJPanel
Tested manually on OSX w/ and w/o HiDPI Retina:

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)]

instances; Removing ref. at API destroy() is wrong ; Allow GC to clear ..
- Removing ref. at API destroy() is wrong
- Since all instances can be recreated, removing ref at destroy() is simply wrong.
- Keep weak references until GC collects, i.e. user does not claim them anymore.
- Safe for Display, since it holds it's EDT thread.
- Window/Screen .. if user abandons reference .. nothing we can do here.
- Allow GC to clear ..
No need to hold ref loonger than user.

between Java GL- and CALayer thread ; Simplify / Fix waitUntilRenderSignal().
Stuttering caused by lack of GL resource synchronization between Java GL- and CALayer thread
+ // Required(?) to finish previous GL rendering to give CALayer proper result,
+ // i.e. synchronize both threads each w/ their GLContext sharing same resources.
+ //
+ // FIXME: IMHO this synchronization should be implicitly performed via 'CGL.flushBuffer(contextHandle)' above,
+ // in case this will be determined a driver bug - use a QUIRK entry in GLRendererQuirks!
+ gl.glFinish();
Simplify / Fix waitUntilRenderSignal()
- remove loop and 'ready' condition -> nonsense
- if too later, i.e. lastWaitTime+TO < now, use now+TO as max. vsync waiting time
Bug735 Tests:
- Make vsync, wait and ECT (exclusive context thread) configurable via main args.
- Inv2*, Inv3* and Inv4*: Fluent Animation
- Works w/ ECT

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(..).

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.

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().

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.

896e8b021b39e9415040a57a1d540d7d24b02db1): Run on main-thread w/o blocking ; Misc Changes
Commit 896e8b021b39e9415040a57a1d540d7d24b02db1 moved all native CALayer calls to the current thread
to avoid deadlocks.
Even though this seemed to be fine at least resource GC (release/dealloc calls) were issued
very late in time, probably due to multithreading synchronization of JAWT and/or OSX API.
Example: Our 'TestAddRemove01GLCanvasSwingAWT' test didn't freed CALayer resources incl. GL ctx
when destroying the objects (AWT Frame, GLCanvas, ..), leading to resource starvation .. eventually.
Remedy is a compromise of behavior before commit 896e8b021b39e9415040a57a1d540d7d24b02db1
and that commit, i.e. to run CALayer lifecycle methods on main-thread, but do not block!
The careful part within MacOSXCGLContext.associateDrawable(..) performs the following block on main-thread:
- lock the context
- create NSOpenGLLayer (incl. it's own shared GL context and the DisplayLink)
- attach NSOpenGLLayer to root CALayer
- unlock the context
Due to the GL ctx locking, this async offthread operation is safe within our course of operations.
Details:
- NSOpenGLContext
- Context and CVDisplayLink creation at init
- Call [ctx update] if texture/frame size changed
- 'waitUntilRenderSignal' uses default TO value if given TO is 0 to avoid deadlocks
+++
Misc Changes:
- Fix object type detection: isMemberOfClass -> isKindOfClass
- OSXUtil_isNSView0
OSXUtil_isNSWindow0,
CGL_isNSOpenGLPixelBuffer
- MacOSXCGLDrawable/MacOSXPbufferCGLDrawable: remove getNSViewHandle() method.
MacOSXCGLContext uses common code to detect nature of the drawable handle.
- MacOSXCGLContext/CALayer: Use safe screenVSyncTimeout values, never 0 to avoid deadlock!
- JAWTWindow.invalidate: Call detachSurfaceLayer() if not done yet

RunOnMainThread(waitUntilDone:=true,..) can deadlock the main-thread if called from AWT-EDT,
since the main-thread may call back to AWT-EDT while injecting a new main-thread task.
This patch revises all RunOnMainThread CALayer usage, resulting in only one required left:
- OSXUtil.AddCASublayer() w/ waitUntilDone:=false
Hence the CALayer code has no more potential to deadlock main-thread/AWT-EDT.
OSXUtil.AddCASublayer() must be performed on main-thread, otherwise the
CALayer attachment will fail - no visible rendering result.
+++
Note: A good trigger to test this deadlock is to magnify/zoom
the OSX desktop (click background + ctrl-mouse_wheel)
before running some unit tests.
TestGLCanvasAWTActionDeadlock01AWT and TestAddRemove02GLWindowNewtCanvasAWT

(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.

Semantics of 'lastContext' are plain wrong, since release() override does claim the previous 'lastContext'
is current at the end - however, it wasn't technically made current.

where our CALayer is moved out of the visible area
- same erroneous behavior for GLCanvas and NewtCanvasAWT
- sized-frame: Set framesize and validate() it
- sized-component: Set component preferred size and call frame.pack()
- added workaround 'OffscreenLayerSurface.layoutSurfaceLayer()' to fix CALayer size, which snaps for:
- OK initial size before setVisible: sized-frame and sized-component
- OK resize w/ sized-frame
- OK manual frame resize
- Invisible: w/ sized-component after setVisible()
++
- CALayer-Sublayer (GL) has additional retain/release when added/removed
to be on safe side.

main-thread deadlock'ed due to locked shared context
NSOpenGLLayer::openGLContextForPixelFormat(..) is performed on main-thread at 1st NSOpenGLLayer display method.
This happened irregulary, i.e. sometimes (T0) right after NSOpenGLLayer creation and attachSurfaceLayer()/AddCASublayer(..),
sometimes later (T1).
NSOpenGLLayer::openGLContextForPixelFormat(..) uses the passed shared user context.
The shared user context is locked at NSOpenGLLayer's creation (T0) and if performed at this early time
the call deadlocks due to pthread_mutex wait for the shared user context.
This fix performs NSOpenGLLayer creation and layer attachment while the shared user context
is kept unlocked and enforces NSOpenGLLayer display and hence NSOpenGLLayer::openGLContextForPixelFormat(..).
Added CGL.setNSOpenGLLayerEnabled(..) to enable/disable NSOpenGLLayer - currently not used.
- Passed AddRemove tests for GLCanvas/Swing and GLWindow/NewtCanvasAWT w/ 100 loops on Java6 and Java7 on OSX.
- Passed Instruments Leaks test w/ 10 loops on Java6 and Java7

'CGL.releaseNSOpenGLLayer' triggers release - but very late w/ AWT usage.
OSXUtil_RemoveCASublayer0's added '[subLayer release]' in commit f6e6fab2a7ddfb5c9b614cb072c27ff697629161
is wrong, since 'CGL.releaseNSOpenGLLayer' actually does trigger it's release.
This was not seen w/ AWT tests, since it happens very later.
A NewtCanvasAWT test disclosed this error -> removed that extra release call.
The culprit for the late release w/ AWT usage was CGL.createNSOpenGLLayer's call in the current thread.
Moving it to the Main-Thread fixed the problem.
All CALayer lifecycle calls are issued on the Main-Thread now.
NSOpenGLLayer's CVDisplayLink OpenGL fitting via 'CVDisplayLinkSetCurrentCGDisplayFromOpenGLContext'
is now performed at it's context creation in 'NSOpenGLLayer::openGLContextForPixelFormat'.
The 'extra' release of the NSOpenGLLayer's NSOpenGLContext as introduced in commit f6e6fab2a7ddfb5c9b614cb072c27ff697629161
is still valid.

Layers and native GL-Context are _not_ Released ; Java Side wait for Main-Thread
- Fix Bug 690: Occasional Freeze on CVDisplayLinkStop
- NSOpenGLLayer.disableAnimation() shall not claim the renderLock mutex,
since the CVDisplayLink callback could be waiting for the lock.
This waiting callback could freeze the call to CVDisplayLinkStop.
- Fix Bug 691: Layers and native GL-Context are _not_ Released
- Following proper release cycle:
Context unrealized:
- JAWTWindow.detachSurfaceLayer() -> OSXUtil.RemoveCASublayer(..)
- CGL.releaseNSOpenGLLayer(..)
JAWTWindow.destroy()
- MacOSXJAWTWindow.UnsetJAWTRootSurfaceLayer(..)
- OSXUtil.DestroyCALayer(..)
- 'Magic' CALayer release calls (w/o manual retain beforehand) at:
- OSXUtil.RemoveCASublayer(..): [subLayer release]
- MacOSXJAWTWindow.UnsetJAWTRootSurfaceLayer(..): [rootLayer release]
- OSXUtil.DestroyCALayer(..): [rootLayer release]
- 'Magic' NSOpenGLLayer's NSOpenGLContext dealloc:
- [NSOpenGLContext clearDrawable]
- CGLDestroyContext( [NSOpenGLContext CGLContextObj] )
- Java Side wait for Main-Thread
- Waiting for the delegated Main-Thread on the Java side eases debugging
and won't block the Main-Thread in native code.
- Utilizing this for all CALayer calls
Test case: TestGLCanvasAddRemove01SwingAWT
