- * 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.
