Module: Mesa
Branch: master
Commit: f23c3ebeccc5c591b79c10cbdb693270ef27a2f5
URL: http://cgit.freedesktop.org/mesa/mesa/commit/?id=f23c3ebeccc5c591b79c10cbdb693270ef27a2f5

mesa: Declare _mesa_meta_begin()/end() as public
Declare _mesa_meta_begin()/end() in meta.h so that drivers can write
custom meta-ops (such as HiZ resolves for i965).
This necessitates moving the the META_* macros into meta.h. To prevent
naming collisions, this commit renames each macro to be MESA_META_*.
