From: Kenneth Graunke Date: Tue, 9 Aug 2011 17:53:29 +0000 (-0700) Subject: glsl: Implement the GL_ARB_conservative_depth extension. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b9eb4d8a59699e233255113acafae220c3d8fe3c;p=mesa.git glsl: Implement the GL_ARB_conservative_depth extension. It's the same as GL_AMD_conservative_depth. The specs have slight differences in wording, but don't differ in content or behavior.
