| 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. |
