** QGL_WIN.C
**
** This file implements the operating system binding of GL to QGL function
** pointers. When doing a port of Quake2 you must implement the following
** two functions:
**
** QGL_Init() - loads libraries, assigns function pointers, etc.
** QGL_Shutdown() - unloads libraries, NULLs function pointers
*/
/*
* This causes glDisable(), glEnable(), glCullFace() and glPolygonMode() to
* be wrapped in order to get around a bug in ATI's FireGL drivers.
