Unfortunately slows down fill by a couple percent. :(\r\n\r\nPre-fix (most notable with blurring enabled, since we convert back-and-forth between sRGB 3 times. We should probably avoid this in the future to make fill rate larger.)\r\n![pre](http://i.imgur.com/gUPImYG.png)\r\n\r\nPost-fix (also has blur applied, just a smaller filter kernel in this case.
