* Filename:     mglmesa.h 
* Version:      Revision: 1.1.1.1 
* 
* Language:     ANSI C 
* Environment:  Any 
* 
* Description:  Header file for the Mesa/OpenGL interface bindings for the 
*               SciTech MGL graphics library. Uses the MGL internal 
*               device context structures to get direct access to the 
*               high performance MGL rasterization functions for maximum 
*               performance. Utilizes the VESA VBE/AF Accelerator Functions 
*               via the MGL's accelerated device driver functions, as well 
*               as basic DirectDraw accelerated functions provided by the 
*               MGL.
