 * It's designed to be gl.h-independent as well.  That is, it does
 * not depend on any particular extensions being defined in the gl.h
 * header.  We #define extension symbols (like _GLAPI_EXT_blend_color)
 * to determine which entry points to compile.  Clients of this dispatcher
 * (like Mesa) can #ifdef test these symbols to know how to fill in the
 * table.
