* Separate GLFbo and GLExt implementations. GLFbo can now be implemented either via vanilla OpenGL3 calls or GL_EXT_framebuffer_*** extensions (OpenGL2.1- only).
* Use modern way of getting supported extensions in core profile.
* Luminance and Alpha formats are not available when running in core profile.
* Bind a dummy vertex array object (VAO) when running in core profile.
* Point sprite mode is always enabled. Since both OpenGL ES 2.0 and OpenGL 3.2 core require it, jME3 is no longer capable of rendering regular points.
* this is required for pregenerated mipmaps in e.g. DDS files
* others checks are added to make sure a zero-length buffer cannot be uploaded (that's an error for now)
* Add new "Limits" enum to hold maximums of various renderer capabilities such as texture size
* Add support for seamless cubemap (enabled by default for mipmapped cubemaps)
* Fix conflict when using GL tracing with GL debugging
- When GraphicsDebug is enabled, check for GL errors and display hints from the driver
- When GraphicsTrace is enabled, dump OpenGL calls on the console
* Unified all renderers into common class 'ALAudioRenderer'
* LWJGL and Android now implement the AL / ALC / EFX interfaces to provide a common OpenAL backend for jME
* Added support for OpenAL Soft "Pause Device" extension, which allows the engine to pause the context while running in the background (currently requires OpenAL soft 1.16 and thus is Android only feature)
(so far only for lwjgl because I'm lazy)
Went ahead and added in divisor support while I was
at it because it doesn't cost anything and there might
be use-cases for it.
Mesh now knows about instances and you can directly
ask it for an instance count. I haven't added support
for proper bounding box calculation but it should
at least be possible now.
* All GL calls are done via static imports
* Once again remove dependency on GL21 / GL30 - with the generator it will be possible to choose whether to target GL2+extensions or GL3 core
* ContextCapabilities is field in Renderer, not allowed to use GLContext to retrieve it anymore
* Assume depth textures are always supported (they should be since GL1.4)
