From 5324f9c48d59ef966fbab03664a8d44ea8c19c5f Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Wed, 28 Sep 2011 11:15:01 -0700 Subject: [PATCH] swrast: When asked to map a slice of a 1D array, give back that slice. Until now, we've been treating 1D arrays as a single slice, and each array slice is actually just a row of the 2D texture. While swrast still stores them this way, hardware drivers think that 1D arrays have actual separate slices not stored as contiguous rows.
