From d7707ef5a554ca0a1ec17b9491055e8c8db570c4 Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Wed, 4 Apr 2012 16:04:00 -0600 Subject: [PATCH] svga: return 1 for PIPE_CAP_VERTEX_COLOR_UNCLAMPED query MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Before, we weren't clamping the vertex colors produced by ARB vertex programs. This could result in some rendering being too bright (in ETQW, for example). Also add cases for PIPE_CAP_VERTEX_COLOR_CLAMPED and PIPE_CAP_FRAGMENT_COLOR_CLAMPED with comments to be complete.
