* A pseudo-GLX implementation to allow GLX-based OpenGL programs to
* work with Mesa.
*
* Notes:
* 1. If the visual passed to glXGetConfig was not one returned by
* glXChooseVisual then the GLX_RGBA and GLX_DOUBLEBUFFER queries
* will always return True and the GLX_DEPTH_SIZE query will always
* return non-zero.
* 2. The glXIsDirect() function always returns True.
