From 96db07e28c165610b809a9fd88410a82a24a893e Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Mon, 17 Oct 2011 14:34:52 -0700 Subject: [PATCH] intel: Enable stripping of texture borders. This replaces software rendering of textures with the deprecated 1-pixel border (which is always bad, since mipmapping is rather broken in swrast, and GLSL 1.30 is unsupported) with hardware rendering that just pretends there was never a border (so you have potential seams on apps that actually intentionally used the 1-pixel borders, but correct rendering otherwise). This doesn't regress any piglit tests on gen6 (since the texwrap border/bordercolor cases already failed due to broken border color handling), but regresses texwrap border cases on original gen4 since those end up sampling the border color instead of the border pixels. It's a small price to pay for not thinking about texture borders any more.
