[Mesa-dev] [PATCH 13/14] intel: Change signature of intel_context.vtbl.set_draw_region

chad at chad-versace.us chad at chad-versace.us
Wed May 4 13:33:57 PDT 2011


From: Chad Versace <chad.versace at intel.com>

Add additional parameter 'struct intel_region *stencil_region'.
A subsequent patch uses the new parameter to update
brw_context.state.stencil_region.
