From 147d0102952b7c0b16906c08da2ae447ec68185a Mon Sep 17 00:00:00 2001 From: Kenneth Graunke Date: Wed, 29 Jun 2011 15:11:22 -0700 Subject: [PATCH] i965/gen7: Fix point sprite texture coordinate overrides. This is exactly analogous to Eric's Gen6 change in commit f304bb8a5d040d99db47a65813d216d11c66fb47. His explanation: "We were assuming that the input attribute n to the FS was FRAG_ATTRIB_TEXn, which happened to be true often enough for our testcases."
