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(..).

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.

AnimatorBase: Add setModeBits/MODE_EXPECT_AWT_RENDERING_THREAD; FPSAnimator: Make transactions deterministic.
ExclusiveContextThread (ECT) allows user to dedicate a GLContext to a given thread.
Only the ECT will be allowed to claim the GLContext, hence releasing must be done on the ECT itself.
The core feature is accessible via GLAutoDrawable, while it can be conveniently enabled and disabled
via an AnimatorBase implementation. The latter ensures it's being released on the ECT and waits for the result.
Note that ECT cannot be guaranteed to work correctly w/ native (heavyweight) AWT components
due to resource locking and AWT-EDT access. This is disabled in all new tests per default and
noted on the API doc.
Note: 'Animator transaction' == start(), stop(), pause(), resume().
- Add ExclusiveContextThread (ECT) feature
- GLAutoDrawable NEW:
- Thread setExclusiveContextThread(Thread t)
- Thread getExclusiveContextThread()
- AnimatorBase NEW:
- Thread setExclusiveContext(Thread t)
- boolean setExclusiveContext(boolean enable)
- boolean isExclusiveContextEnabled()
- Thread getExclusiveContextThread()
- AnimatorBase: Add setModeBits/MODE_EXPECT_AWT_RENDERING_THREAD
Allows user to pre-determine whether AWT rendering is expected before starting the animator.
If AWT is excluded, a more simple and transaction correct impl. will be used.
- FPSAnimator: Make transactions deterministic.
FPSAnimator previously did not ensure whether a transaction was completed.
A deterministic transaction is required to utilize ECT.
FPSAnimator now uses same mechanism like Animator to ensure completeness,
i.e. Condition and 'finishLifecycleAction(..)'. Both are moved to AnimatorBase.
Tested manually on Linux/NV, Linux/AMD, Windows/NV and OSX/NV.
- All new tests validated correctness.
- All new tests shows an performance increase of ~3x w/ single GLWindow, where multiple GLWindows don't show a perf. increase.

- GLArrayDataWrapper's init() only validated and set the 'name' for VBO ARRAY_BUFFER usage and validates it,
regardless of FFP or GLSL usage.
- GLArrayDataWrapper's init() included the no-VBO case to the above 'name' set/validate code path.

One FloatStack for each, MV, P and T, with initialialSize zero to save memore
and growSizes: MV = 16 arrays, P = 2 arrays, T = 2 arrays,
with array = 16 floats.
This shall save performance due to the preallocated stack when used
and growing only in the above mentioned grow intervals.
We may finetune the growSize, if required.

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)

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.

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.

creation is not possible on AWT-EDT.
The Intel HD3000 OpenGL driver on Windows will deadlock @ SwapBuffers in case the drawable is created
on a thread other than the window owner thread.
We are aware of such possibilities, nevertheless the AWTEDTExecutor.singleton.invoke(..)
allowed to execute the runnable in case it cannot be invoked on AWT-EDT.
The latter is the case if the current thread is not the AWT-EDT _and_ is holding the AWT tree-lock.
With GlueGen commit 0b43b43f889ad7fc220942b0076e2001ca3cf13f, the invoke method now consumes
an argument allowing to restrict the execution to AWT-EDT only.
In such case, the drawable will be realized at a later time from the AWT-EDT.
Such a situation could be triggered if a Frame's setVisible(true)
is not issued from the AWT-EDT, as it should be!
However, to relax such use cases - we better recognize such possible dealock and avoid it.

GLCanvas.displayOnEDT: Also check null!=drawable
As for 1ae0737f34143a5ed655bd9c4d5fe9b0437c7774, an animator may inject a display Runnable on the EDT
before AWT destruction. In case this Runnable is executed after destruction on the EDT - it would fail.

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.

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

GLCapabilities on X11 (feature complete)
To allow custom GLCapabilities, we had to use native parenting on X11 w/ a new child window.
The desired visualID chosen by the users GLCapabilities is passed to the new child window.
The redraw drops must be caused by the original GDK or the new child GDK window.
Now we use a plain X11 child window similar to NEWT's X11 window and NewtCanvasSWT,
which doesn't expose this bug.
(Note: SWTAccessor/GLCanvas still contains the uncommented GDK code path for further inspection, if desired)
Also added SWTNewtEventFactory to test event handling on the SWT GLCanvas w/ GearsES2.
TestSWTJOGLGLCanvas01GLn tests custom GLCapabilities now.
SWTEDTUtil has been moved to private: com.jogamp.newt.swt -> jogamp.newt.swt.

DisposeListener; Run GL tasks on current thread w/o restrictions
Fix dispose bug, check for isDisposed() and add DisposeListener
- Don't issue SWTAccessor.setRealized(..), since it's called implicit via super.dispose()
- Check isDisposed() ..
- add DisposeListener to act on parent's disposal (Shell, Composition, ..)
Run GL tasks on current thread w/o restrictions
+ * The current thread seems to be valid for all platforms,
+ * since no SWT lifecycle tasks are being performed w/ this call.
+ * Only GL task, which are independent from the SWT threading model.

caps/pixelformat w/ chosen GLProfile only
Using a pixelformat w/ chosen stencil for CALayer does corrupt rendering for an unknown reason,
probably due to incompatible pixelformat w/ CALayer composition.
This patch simply discards any special chosen caps, while only recognizing the desired GLProfile
for the FBO CALayer pixelformat.
