From 6ba8f0688a35ffac93bd025739aefe8e3694ca0c Mon Sep 17 00:00:00 2001 From: Yuanhan Liu Date: Fri, 18 Nov 2011 09:49:51 +0800 Subject: [PATCH] swrast: simplify the prototype of function texture_combine Parameter n and rgbaChan are both from structure span, thus using span as paramter to simplify the prototype. Function texture_combine is only used by _swrast_texture_span, so I guess it's safe to do so. This patch is mainly for the next patch.
