From 51e5a266c1e1c12c4f0d82bee3caff008a41c9fd Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Wed, 23 Nov 2011 10:20:12 -0800 Subject: [PATCH] i965/fs: Fix regression in fbo-alphatest-nocolor. In the refactor for handling user-defined out params, we failed to set up the new color output tracking when there was no color drawbuffer in place but alpha testing was on. Just always set up at least one when handling gl_FragColor, since we won't make use of its value unless we need to.
