NOTES
known BUGS with known cause (no bugreports please!, but patches are welcome :) )
horizontal MMX2 scaler reads 1-7 samples too much (might cause a sig11)
Supported output formats BGR15 BGR16 BGR24 BGR32
BGR15 & BGR16 MMX verions support dithering
Special versions: fast Y 1:1 scaling (no interpolation in y direction)
TODO
more intelligent missalignment avoidance for the horizontal scaler
bicubic scaler
dither in C
change the distance of the u & v buffer
