  Hash : 6d94f064
  Message : Add more complete NULL driver for the GL back-end. This implements a NULL driver in OpenGL by stubbing out most of the GL functions in FunctionsGL except a few static "Gets" that are needed for initialization with Chromium and the tests. It is intended to be used for performance testing ONLY and will not have correct behaviour. It also adds a define to enable conditionally excluding the null entry points for implementations that wish to save on a bit of binary size. Also fixes some of the typedefs in functionsgl_typesdefs.h that were turned up after implementing the direct assignment from NULL stub entry point, generated from gl.xml, to the function pointer with type defined from functionsgl_typedefs.h.
