-/**
- * \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.
