  /**
   * \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.
