Ronald S. Bultje e0c3e07387 sws: implement MMX/SSE2/SSSE3/SSE4 versions for horizontal scaling.
Speed: from 3.9x to 9.6x speed improvement over C, and some small
(up to 15%) speed improvements over existing MMX code (particularly
for bigger filters).

Ronald S. Bultje 3f04ab4fcd swscale: split hScale() function pointer into h[cy]Scale().
This allows using more specific implementations for chroma/luma, e.g.
we can make assumptions on filterSize being constant, thus avoiding
that test at runtime.
