  14 * Description:  Header file for the Mesa/OpenGL interface bindings for the
  15 *               SciTech MGL graphics library. Uses the MGL internal
  16 *               device context structures to get direct access to the
  17 *               high performance MGL rasterization functions for maximum
  18 *               performance. Utilizes the VESA VBE/AF Accelerator Functions
  19 *               via the MGL's accelerated device driver functions, as well
  20 *               as basic DirectDraw accelerated functions provided by the
  21 *               MGL.
