| * \mainpage Mesa GL API Module |
| * |
| * \section GLAPIIntroduction Introduction |
| * |
| * The Mesa GL API module is responsible for dispatching all the |
| * gl*() functions. All GL functions are dispatched by jumping through |
| * the current dispatch table (basically a struct full of function |
| * pointers.) |
| * |
| * A per-thread current dispatch table and per-thread current context |
| * pointer are managed by this module too. |
| * |
| * This module is intended to be non-Mesa-specific so it can be used |
| * with the X/DRI libGL also. |
