This changes the drawing paradigm a bit. The VAO configuration is done JIT-style and depends on context active shader. This is to allow more flexibility for implementations to do optimization at lower level. The vao cache is now its own class to isolate the concept. It is this class that is reference by the GLContext for ownership of the containing VAO ids.
