GL_RGBA/GL_ALPHA ; Load dedicated native libav/libffmpeg
- ES2 spec does not allow GL_RGBA/GL_ALPHA.
- Load dedicated native libs (libav/libffmpeg) since distributions don't create
symlink e.g. libavutil.so -> libavutil.so.53

Without GLX but X11 windows, there is no pre-configured X11GLXGraphicsConfigurationFactory set,
hence fetch the fallback X11GraphicsConfigurationFactory via:
GraphicsConfigurationFactory.getFactory(com.jogamp.nativewindow.x11.X11GraphicsDevice.class, CapabilitiesImmutable.class)

EGLDisplay's eglInitialize(..) fails ; Fix EGLDrawableFactory.getEGLSurface()
- EGLDisplayUtil: Workaround (latest) PVR 540 EGL regression where 3nd EGLDisplay's eglInitialize(..) fails
In this case and if eglGetDisplay(..) fails w/ a non EGL_DEFAULT_DEVICE, fall back to EGL_DEFAULT_DEVICE - always.
This workaround actually simplifies handling both cases.
- Fix EGLDrawableFactory.getEGLSurface()
Tests whether a given NativeSurface w/ EGLGraphicsDevice and EGLGraphicsConfiguration
has a valid EGL Surface. Only if true, reuse the whole NativeSurface,
otherwise construct the missing pieces (device, config and use a WrappedSurface for EGL).

offscreen drawables, reported by Mark Raynsford
New common GLAutoDrawableBase missed to close the AbstractGraphicsDevice
in case it has been created and dedicated for the passed GLDrawable.
This detailed knowledge is only known to the creator, hence it is passed
in the constructor and is being passed through all specializations.
Further more the new X11/GLX impl. of GLDrawableFactory's
'createMutableSurfaceImpl' always creates it's own private X11 display connection
to avoid locking / threading issues. Since the old implementation reused the
shared display connection which is prone to threading issues, this bug was not visible before.
Also fixed the unit test TestNEWTCloseX11DisplayBug565,
now correctly validating that no display connection is left over
after a new cycle of create/destroy of onscreen and offscreen drawables.

This might be required by a few older buggy ES implementations.
Also assists to discable ANGLE is not properly detected (?)
on Windows 32bit - the latter causes SEGV within FF and Chrome.

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.

capabilities-type; Add a pre-set nativeVisualID to chooseGraphicsConfiguration(..)
Map factory to device-type _and_ capabilities-type:
- Allows using different GraphicsConfigurationFactory implementations for different capabilities-types.
Previous impl. failed to use an OpenGL agnostic CapabilitiesImmutable for 'chooseGraphicsConfiguration(..)'
since only the GL aware factory was mapped. The latter failed since it expected a GLCapabilitiesImmutable.
- The passed capabilities-type as well as device-type given at getFactory(..)
is traversed top-to-down to find a most suitable factory:
For-All devT := getTopDownDeviceTypes(deviceType)
For-All capsT := getTopDownCapabilitiesTypes(capabilitiesType)
f = factory.get(devT, capsT);
if(f) { return f; }
end
end
Add a pre-set nativeVisualID to chooseGraphicsConfiguration(..)
- In situations where a native visualID is already chosen [by external means for example],
but we still need to query a matching GraphicsConfiguration - we require to pass
a non VisualIDHolder.VID_UNDEFINED nativeVisualID.
We had a hack implemented before within some implementations and their static calls,
however an agnostic mechanism is required to implement new NativeSurface/Window's
platform agnostic.
- X11GLXGraphicsConfigurationFactory: respect a pre-set xvisualID
- X11GLXDrawableFactory.createProxySurfaceImpl(..) queries the given windowHandle's
visualID and 'chooses' the configuration accordingly. If the visualID is undefined
an exception is thrown, since window is invalid.
These mechanics are implicit for Windows and OSX.
Fix X11GLXGraphicsConfiguration.updateGraphicsConfiguration():
- Skip any action if a valid X11GLCapabilities is already chosen, i.e. w/ visualID.
Otherwise choose a suitable configuration incl. visualID.
The latter is quite impossible and invalid, since visualID must be defined at window creation time
and the update method is issued with a valid window.
X11 - Misc:
- Added 'int jogamp.nativewindow.x11.X11Lib.GetVisualIDFromWindow(..)'
- All returned visualID's are of type 'int'

GLAutoDrawable multi-threading w/ proper pattern (hope so)
Considering code changes and remarks:
3ed491213f8f7f05d7b9866b50d764370d8ff5f6
1a91ec5c8b6fd9d9db7bc115569c369fe7b38e9b
3334a924309a9361a448d69bc707d4cce416b430
4f27bcecf7484dc041551f52a5c49e2884cb3867
It seems necessary to have
- recursive locking employed for all semantic actions which changes drawable & context (and the Window resource)
- to avoid deadlock, we have to ensure the locked code segment will not spawn
off to another thread, or a thread holds the lock, spawns of an action requiring the lock. .. sure
- other read-only methods (flags, ..) shall at least utilize a safe local copy of a volatile field
if further use to produce the result is necessary.
- flags like sendReshape require to be volatile to guarantee it's being processed
Patch impacts: AWT/SWT GLCanvas, GLAutoDrawableBase [and it's specializations]
and hopefully closes any loopholes of missing a cache hit, etc.
If you review this and find optimizations, i.e. removing a lock due to semantics etc,
don't hold back and discuss it, please.

- Use pbuffer (still), don't set FBO (invisible)
- OLS (only impl is JAWTWindow now) stores the attached layer handle
created and attached by the GLContext implementation,
so 'others' may detach it -> NewtCanvasAWT
- NewtCanvasAWT.removeNotify() needs to ask the OLS to detach the layer
since it's parent will be gone.
- MacOSXCGLContext destroy allows a removed OLS (see above)

setting by setSampleBuffers(true) and setBackgroundOpaque(false)
This bug lead to X11 GLCapabilities rgba: 8/8/8/1 - which ofc is invalid. Sideeffect was a bad selected GLXFB configuration
and the GLContext couldn't be made current.
Patch sets alpha bits reflecting reality carefully after opaque/samples. Added API doc note.

- 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

EGLDisplayUtil adds creation of EGLGraphicsDevice.
Due to EGL's location in JOGL, supporting destruction of an EGLGraphicsDevice
is solved (hack) temporary by passing an eglTerminate callback to it's ctor.
Using EGLGraphicsDevice's close() method to also issue eglTerminate() simplifies the code.
In future we shall move EGL to nativewindow!

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

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

- GLAutoDrawable (compat change - recompile):
- 'void invoke(boolean wait, GLRunnable glRunnable)' -> 'boolean invoke(boolean wait, GLRunnable glRunnable)'
Allows notifying caller whether the task has been executed or at least enqueued.
- GLAutoDrawable add 'GLEventListener removeGLEventListener(int index)'
- This allow one to remove a specific GLEventListener and reusing it (return value).
- GLDrawableImpl remove 'destroy()' to favor 'setRealized(false)'
- Using more common code of GLAutoDrawableBase, i.e. GLPbufferImpl can use defaultDestroyOp().
- Removes redundancy of methods
- GLAutoDrawableBase/Delegate
- better 'default' names to emphasize it's purpose, adding API doc
- includes more generic functionality
- defaultWindowDestroyNotify()
- defaultDestroyOp()
- TestGLAutoDrawableDelegateNEWT demonstrates a simple example w/ all window events handled.

locking ; Revise threading code; Proper name for SWT unit tests.
SWT GLCanvas:
- Fix destroy()
drawable.setRealized(false); is being called within dispose() method
- Remove local concurrency hack
[MT-0] The hack: 'final GLContext ctx = getContext(); a = null != ctx ? ctx.something() : 0;'
is thread safe locally, however, w/o covering the hole use case of the caller
it makes no sense to add thread safe code here - would be only an illusion.
In case any of the methods are called outside of a locked state
extra care should be added. Maybe we shall expose locking facilities to the user.
However, since the user shall stick to the GLEventListener model while utilizing
GLAutoDrawable implementations, she is safe due to the implicit locked state.
- Removing out-of-process locking
[MT-1] Claiming the recursive lock in the dispose/display/.. methods
and _then_ issuing a complex off-thread GL task could lead to deadlock.
The GL task could involve calling GLEventListener methods, which itself
could try to manipulate the GLCanvas -> deadlock.
Similar to [MT-0] we may need to either find a proper locking mechanism
or simply ignore it and reduce functionality.
TBH .. the number of scenarious of the mentioned deadlock are very limited
and exotic.
- Revise threading code
[MT-2] Besides the other MT-* remarks, the logic whether to spawn off
the GL task and determination which thread to use is too complex and redundant.
(See isRenderThread(), runInGLThread() and runInDesignatedGLThread())
- Proper name for SWT unit tests.
Reflect the semantics.

GL_ARB_half_float_pixel/GL_ARB_half_float_vertex and GL_OES_texture_half_float extensions
We mistakenly aliase the GL2 and GLES2 extensions:
- GL_ARB_half_float_pixel
- GL_HALF_FLOAT_ARB 0x140B
- GL_ARB_half_float_vertex
- GL_HALF_FLOAT 0x140B
- GL_OES_texture_half_float extensions
- GL_HALF_FLOAT_OES 0x8D61
This also leads to adding GL_HALF_FLOAT_OES
to com.jogamp.opengl.util.GLBuffers.sizeof(..).

Font::getAdvancedWidth(..) allows applications to query a glyphs width
with a given pixel size, as it is being used for rendering.

1. Drawable, 2. GLContext
Remove deadlock situation where thread-1 (Animator Thread) holds the GLContext-Lock
and acquires the Surface-Lock, while thread-2 (UI/Main/EDT) holds the Surface-Lock
and attempts to create the GLContext and hence acquires the GLContext-Lock.
A GLContext-Lock and hence makeing the GLContext current requires to hold
the Surface-Lock. The prev. code acquired the locks in reverse order and
allowed the deadlock as described above.
This fix acquires the locks in the proper natural order
1 - Surface-Lock
2 - GLContext-Lock
This fix also renders the use of the non-synchronized behavior invalid,
since it is bogus not to wait for the GLContext lock where it waits for the
Surface lock. It also seems nonsense not to wait for any of both locks
and our code always waited for both (synchronized := true).
The GLContext [set/is]Synchronized(..) methods are removed
and waiting for the lock per default is the correct behavior.

ProjectFloat Matrix Multiplication of gluUnProject(..) impl.
ProjectFloat's previous gluMultMatricesf(..) used row-major order,
but the replacement multMatrixf(..) uses column-major order (like OpenGL, ..).
Note: The replaced 'gluMultMatrixVecf' by multMatrixVecf() already
used column-major order.
Fix: Reverse the arguments of matrix multiplication
m1 x m2 -> m2 x m1
Added proper API documentation in FloatUtil -> Column Major Order of Linear Matrix Layout

disable support per default.
We have to disable support for ANGLE, the D3D ES2 emulation on Windows provided w/ Firefox and Chrome.
When run in the mentioned browsers, the eglInitialize(..) implementation crashes.
This behavior can be overridden by explicitly enabling ANGLE on Windows by setting the property
'jogl.enable.ANGLE'.
EGLDrawableFactory:
- destroy(): clear references and unregister factory, maybe triggered by GLProfile (ANGLE case)
- getAvailableCapabilitiesImpl(): return empty list in case EGL/ES is n/a (ANGLE case)
