 * =======================================================================
 *
 * 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 implementation should work for Windows and unixoid platforms,
 * other platforms may need an own implementation.
