From 776971218ef6c6749fcb882a95ae5fc3a1ff5059 Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Fri, 20 Feb 2009 14:06:25 -0700 Subject: [PATCH] gallium: use the TGSI_TEXTURE_SHADOW1D/2D/RECT texture types for TEX instructions These texture types were defined but never put to use. For the time being though, the Mesa->TGSI translater isn't emitting these targets.
