a3f3701cea1ba388e7c877955252bb7375eedebdvboxsync * The Mesa GL API module is responsible for dispatching all the
a3f3701cea1ba388e7c877955252bb7375eedebdvboxsync * gl*() functions. All GL functions are dispatched by jumping through
a3f3701cea1ba388e7c877955252bb7375eedebdvboxsync * the current dispatch table (basically a struct full of function
a3f3701cea1ba388e7c877955252bb7375eedebdvboxsync * pointers.)
a3f3701cea1ba388e7c877955252bb7375eedebdvboxsync * A per-thread current dispatch table and per-thread current context
a3f3701cea1ba388e7c877955252bb7375eedebdvboxsync * pointer are managed by this module too.
a3f3701cea1ba388e7c877955252bb7375eedebdvboxsync * This module is intended to be non-Mesa-specific so it can be used
a3f3701cea1ba388e7c877955252bb7375eedebdvboxsync * with the X/DRI libGL also.
