Re: [Pixman] [PATCH 3/3] BILINEAR->NEAREST filter optimization for simple rotation and translation

2011-05-23 Thread Bill Spitzak
If I understand this right, I also think the "simple" test is all that is needed. The only interesting matrixes are 1:1 scale with integer translations. There are exactly eight arrangements of the upper-left corner: with ±1 in location 0,0 and 1,1, and with ±1 in locations 0,1 and 1,0. I think
