From: Brian Paul Date: Tue, 6 Dec 2011 03:40:48 +0000 (-0700) Subject: swrast: remove core renderbuffer functions from s_renderbuffer.[ch] X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=379e0a3ada995b4cf57d142e0dd4618022e0aadc;p=mesa.git swrast: remove core renderbuffer functions from s_renderbuffer.[ch] We'll use the functions that live in main/ Plus, rename the remaining functions with "swrast_" prefix.
