040abec2534dadc53ebc8fa378ef03f4feecb7dbvboxsync *
040abec2534dadc53ebc8fa378ef03f4feecb7dbvboxsync * The Mesa GL API module is responsible for dispatching all the
040abec2534dadc53ebc8fa378ef03f4feecb7dbvboxsync * gl*() functions.  All GL functions are dispatched by jumping through
040abec2534dadc53ebc8fa378ef03f4feecb7dbvboxsync * the current dispatch table (basically a struct full of function
040abec2534dadc53ebc8fa378ef03f4feecb7dbvboxsync * pointers.)
040abec2534dadc53ebc8fa378ef03f4feecb7dbvboxsync *
040abec2534dadc53ebc8fa378ef03f4feecb7dbvboxsync * A per-thread current dispatch table and per-thread current context
040abec2534dadc53ebc8fa378ef03f4feecb7dbvboxsync * pointer are managed by this module too.
040abec2534dadc53ebc8fa378ef03f4feecb7dbvboxsync *
040abec2534dadc53ebc8fa378ef03f4feecb7dbvboxsync * This module is intended to be non-Mesa-specific so it can be used
040abec2534dadc53ebc8fa378ef03f4feecb7dbvboxsync * with the X/DRI libGL also.
