From 28360fcad75a6917db6af42fb17b81572850ec0d Mon Sep 17 00:00:00 2001 From: Ilia Mirkin Date: Sat, 17 May 2014 22:48:58 -0400 Subject: nv50,nvc0: fix 3d blits with mipmap levels Make sure to normalize the z coordinates as well as the x/y ones when there are mipmaps present. Fixes 3d mipmap generation, which now uses the blit path.
