00014 * Description:  Header file for the Mesa/OpenGL interface bindings for the
00015 *               SciTech MGL graphics library. Uses the MGL internal
00016 *               device context structures to get direct access to the
00017 *               high performance MGL rasterization functions for maximum
00018 *               performance. Utilizes the VESA VBE/AF Accelerator Functions
00019 *               via the MGL's accelerated device driver functions, as well
00020 *               as basic DirectDraw accelerated functions provided by the
00021 *               MGL.
