From b9ef2b85b41272da9ed95071307310f9749cbf2b Mon Sep 17 00:00:00 2001 From: Paul Berry Date: Thu, 15 Sep 2011 15:16:08 -0700 Subject: [PATCH] i965: Enable lower_clip_distance. i965 requires gl_ClipDistance to be formatted as an array of 2 vec4's (as opposed to an array of 8 floats), so enable the lowering pass that performs this conversion.
