|
* 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.
