JOGL GL4 preperation:
- Re-Enable GL3bc native library build, works .. - Adding all the is/get GL4/GL4bc stubs .. - Adding dummy interface GL4 and GL4bc, will be removed when done - Context creation refactoring: - Move Version information to GLContext - Determine version by creation if possible (ARB_create_context), only use the unreliable GL_VERSION string if necessary. - Offering an almost platform independent ARB_create_context path: - createContextARBImpl - platform dependent GLX calls - createContextARB - platform independent setup and version loop
