Description

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.
