GLDrawableUtil.swapGLContextAndAllGLEventListener is safe (Doesn't work w/ pre MSAA onscreen drawable)
GLDrawableUtil.isSwapGLContextSafe(..) allows user to query whether 'we think' it's safe
to utilize swapping of GLContext between GLAutoDrawable instances.
Currently known unsafe cases are:
- between on- and offscreen and one of the following:
- MSAA involved, or
- STEREO involved
Enhanced unit tests in this regard:
- TestGLContextDrawableSwitch02AWT
- using GLContextDrawableSwitchBase0
- TestGLContextDrawableSwitch02NEWT
- using GLContextDrawableSwitchBase0
Utilized safe query for setupPrint(..) action in:
- AWT GLCanvas
- AWT GLJPanel
- NewtCanvasAWT

'ARB_create_context'
Commit e5a55ede324ce500f50991d56491758803063a58 was incomplete,
i.e. it lacked the required mappings for the non ARB profile, i.e.:
GL4bc -> GL3bc, etc.
These profile mappings have been added now.
+++
Further more, GLContext's profile queries, isGL*()
test the ctxOptions for CTX_IS_ARB_CREATED.
This has to be removed to properly work w/ Skip 'ARB_create_context'.
To remove the risk of inconcistency, i.e. context created via ARB and non-ARB,
the 'GLX/WGL profile >= GL3 via non ARB' validation removed
in commit e5a55ede324ce500f50991d56491758803063a58 has been brought back
and refined. Note:
if( glp.isGL3() && createContextARBTried ) {
// We shall not allow context creation >= GL3 w/ non ARB methods if ARB is used,
// otherwise context of similar profile but different creation method may not be share-able.
.. THROW EXCEPTON ..
}
This limited validation removes the possibility of such having a context
of same profile, one created via ARB and one without.
Hence also validates the isGL*() change, where the CTX_IS_ARB_CREATED criteria is removed.
+++
Note regarding commit 7314b47ae1e42997e9e6974b84709640f0ac2a1b (revert):
While analyzing the mapping, it turns out that commit c8b99d197769eaec53c2def562c0ef3fc0e6a9d2
"Don't map compatibility profiles to core profile if the latter are not available (restrict profile aliasing)"
is not fully consistent with GLProfile's and GLContext's profile queries, i.e. isGL*().
We may reiterate over this change .. but have it be reverted for now.

'ARB_create_context' context creation extension via property 'jogl.disable.openglarbcontext'; ...
Only allow the exclusions if platform OS is not OSX:
- jogl.disable.openglcore
- jogl.disable.openglarbcontext
Since on OSX they are known to work reliable and there is not other method
if receiving a higher GL profile than core and ARB.
This also removes the restrictions on X11 and Windows,
where profiles >= GL3 must be created using ARB_create_context.
Hence this is allowed now.

are not available (restrict profile aliasing) ; GLProfile does this - Simplification.
GLContext shall not map compatibility profiles to core profile if the latter is are not available (restrict profile aliasing).
If a user requests a straight GL3 core profile, don't answer with a compatibility profile, e.g. GL4bc.
Hence this patch exposes the true GL profile situation more honestly the the user!
User can already query profile mappings via GLProfile, i.e.
- GL2GL3,
- GL4ES3, or via
- getMaximum
- getMaxFixedFunc
- getMaxProgrammable
- getMaxProgrammableCore
This also fixes an issue when a user requests 'getMaxProgrammableCore'
but would receive a GL4bc profile.

allow FixedFunctionHook to properly determine it's identity
BuildComposablePipeline: Handle synthetic isGL* and getGL* more generic, allow using a prologue hook
as needed for FixedFunctionHook's 'isGL*core()', 'isGLES*Compatible()' and 'getGLProfile()' methods.
The latter FixedFunctionHook take the emulated GL profile GL2ES1 into account,
allowing JOGL code to assume only having GL2ES1 available.
Otherwise methods like Texture.enable(..) would skip the glEnable(TEXTURE_2D)
call and FixedFunctionHook could not enable it's usage.
GLProfile received a 'public static GLProfile createCustomGLProfile(final String profile, final GLProfile profileImpl)'
allowing utilities like FixedFunctionHook to create a generic profile.
BuildComposablePipeline sorts the methods before emitting for better readability.

side vertex arrays
Commit 6136457f10d020c779adc78641d0048f77ab1635 defined hasNoDefaultVAO() as [ GL4, GL3, GLES3 ],
however ES 3.x still supports (deprecated):
- client side vertex arrays
- default vertex array object (VAO)
Setting a custom VAO leads to GL_INVALID_OPERATION for client side vertex arrays
used w/ glVertexPointer(..).
Hence removing GLES3 from hasNoDefaultVAO().

Commit 5166d6a6b617ccb15c40fcb8d4eac2800527aa7b added a workaround for
NVidia's Windows Driver Threaded optimization bug
existing in NVidia driver 260.99 for Window from 2010-12-11.
Commit 007f120cd8d33e4231ef4d207b85ed156d1e0c82
fixed the workaround and made it optional, default: turned off!
Rational of turning the workaround off was due to testing
against the original test-case 'Applet and Webstart'
with drivers >= 266.58 from 2011-01-24,
which did not reproduce this issue.
However, our unit tests reproduced the issue,
e.g. test: com.jogamp.opengl.test.junit.jogl.caps.TestTranslucencyNEWT
Hence we have to re-enable the workaround per default.
Added the following documentation of the issue:
+++
Since NV driver 260.99 from 2010-12-11 a 'Threaded optimization' feature has been introduced.
The driver spawns off a dedicated thread to off-load certain OpenGL tasks from the calling thread
to perform them async and off-thread.
If 'Threaded optimization' is manually enabled 'on', the driver may crash with JOGL's consistent
multi-threaded usage - this is a driver bug.
If 'Threaded optimization' is manually disabled 'off', the driver always works correctly.
'Threaded optimization' default setting is 'auto' and the driver may crash without this workaround.
If setting the process affinity to '1' (1st CPU) while initialization and launching
the SharedResourceRunner, the driver does not crash anymore in 'auto' mode.
This might be either because the driver does not enable 'Threaded optimization'
or because the driver's worker thread is bound to the same CPU.
Property integer value <code>jogl.debug.windows.cpu_affinity_mode</code>:
0 - none (no affinity, may cause driver crash with 'Threaded optimization' = ['auto', 'on'])
1 - process affinity (default, workaround for driver crash for 'Threaded optimization' = 'auto', still crashes if set to 'on')
+++
Note: WindowsThreadAffinity does _not_ work.

use an FBO TextureAttachment if required
We only require an FBO TextureAttachment if using GLSL vertical flip,
otherwise we simply requires a color renderbuffer.
Further, the 'FBO fboFlipped' in GLSL vertical flip mode also simply requires a color renderbuffer.

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.

of commit 5166d6a6b617ccb15c40fcb8d4eac2800527aa7b
Commit 5166d6a6b617ccb15c40fcb8d4eac2800527aa7b added a workaround
for the NVidia driver 260.99 for Window from 2010-12-11 issue.
[1] The workaround sets a process affinity while JOGL initialization
to mitigate NVidia driver's 'Threaded optimization := On' race conditions.
The process affinity is reset reset after initialization.
[2] The process affinity reset code had a bug, i.e. instead to restore the
original process's affinity mask, we restored the system's default affinity mask.
[3] Further more, there seem to be issues with changing a process affinity mask
regarding the process group.
This patch:
- Solves issue [2] by using the original process affinity mask
- Solves issue [3] by allowing a custom
affinity mode via the property 'jogl.debug.windows.cpu_affinity_mode':
- 0 - none (default, no affinity required for Windows NV driver >= 266.58 from 2011-01-24)
- 1 - process affinity (was required w/ Windows NV driver 260.99 from 2010-12-11, see commit 5166d6a6b617ccb15c40fcb8d4eac2800527aa7b)
- 2 - thread affinity (experimental)
Hence the workaround is disabled by default,
since the crash as dicumented in commit 5166d6a6b617ccb15c40fcb8d4eac2800527aa7b
could not be reproduced with NV driver 266.58 from 2011-01-24.

avoiding race conditions.
GLAutoDrawable (API CHANGE) allowing atomic operations:
- Add class API-doc chapter about 'GLAutoDrawable Locking'
- Add method invoke(..) API-doc description about throwing IllegalStateException in case of a detected deadlock situation ahead
(Note: Implemented in GLDrawableHelper.invoke(..) for all implementations)
- Add new methods for proper multithread handling:
- public RecursiveLock getUpstreamLock();
- public boolean isThreadGLCapable();
+++
GLEventListenerState/GLDrawableUtil:
- Perform operation in a atomic fashion,
i.e. lock GLAutoDrawable during whole operations:
- GLDrawableUtil.swapGLContext(..)
- GLDrawableUtil.swapGLContextAndAllGLEventListener(..)
- GLEventListenerState.moveFrom(..)
- GLEventListenerState.moveTo(..)
- ReshapeGLEventListener:
- Moved from GLEventListenerState.ReshapeGLEventListener -> GLDrawableUtil.ReshapeGLEventListener
- Takes 'displayAfterReshape' case into account.
+++
javax.media.opengl.Threading Clarifications:
- Public 'enum Mode', i.e. Threading.Mode
- Public getMode()
- Clarified 'isOpenGLThread()':
- Take 'singleThreaded' into account directly,
i.e. always return 'true' if singleThreaded == false
