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)]
- TODO:
- Use KHR_create_context in EGLContext.createContextARBImpl(..)
- More tests (Mobile, ..)
+++
Misc:
- GLContext*:
- Complete glAllocateMemoryNV w/ glFreeMemoryNV.

- 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

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(..).

Needs GlueGen 6b6b9b3b81cdc85b7260664ebec547756a6be5d7, branch sgothel_wip_fixes01.
I have manually veryfied all changes of the generated GL header - OK!
