| 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.
