From 66b6d5121475ecdd6b76ff660e28dfa6cc3f727c Mon Sep 17 00:00:00 2001 From: Roland Scheidegger Date: Wed, 6 Feb 2013 09:29:55 -0800 Subject: [PATCH] softpipe: fix using optimized filter function This optimized filter (when using repeat wrap modes, linear min/mag/mip filters, pot textures) only applies to 2d textures, but nothing prevented it from being used for other textures (likely leading to very bogus sample results). Note: This is a candidate for the 9.0 branch.
