out by John Burkey. glGetBufferParameterivARB call in glMapBuffer was
too expensive at least with Apple's multithreaded OpenGL
implementation. Now track both bound buffer state (refactored into
GLBufferStateTracker) as well as cache created buffers' sizes
(expressed in GLBufferSizeTracker) and query the cache instead of
OpenGL directly. Verified with VertexBufferObject demo that now no
glGet queries are made at run-time.
