+ *
+ * \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.
