[Mesa-dev] [PATCH 1/3] gallivm: ignore rho approximation for cube maps

2013-10-04 Thread sroland
From: Roland Scheidegger There's two reasons for this: 1) even when ignoring rho approximation for cube maps, the result is still not correct, but it's better as the max error at edges is now sqrt(2) instead of 2 (which was a full mip level), same as it is for ordinary 2d maps when doing rho appr
