Blending testsrc and testsrc2 at hd720 yuv420p I get ~81fps using my
addition. Using lut2 I get ~80 fps. Using no filters and rendering
just those 2 source I get 103 fps.
That is without SIMD though. With SIMD I would expect blend to win.
I'm actually surprised that evaluating the expression isn't dead slow.
