Message : Add an auto-generated dispatch table for GL bindings. This will more easily allow us to extend our implementation to make a NULL or "stub" set of bindings. It also exposes a lot more function permutations via extension variations. It might improve the loading speed for bindings obtained via extensions. Instead of generating a list every time an extension is checked, we use a single std::set for a fast query. However because more extensions are checked for more entry points, it might not make a huge difference. This also fixes an issue where the "real" ANGLE GL headers were being propagated to the entry point dispatch table definitions, instead of being in a totally isolated file. This patch adds the missing typedefs to our proxy headers. It also fixes the naming of a few entry points which was inconsistent with the spec. It also makes an XML adjustment to GL_NV_path_rendering to accomodate a hole in the spec where glLoadMatrixfEXT was not ever defined in OpenGL ES. A spec oddity with the TexStorage extension is not resolved - in this case, some methods are only exposed if other extensions are present, but this information is missing from gl.xml.
