NOTES
-known BUGS with known cause (no bugreports please!)
-code reads 1 sample too much (might cause a sig11)
+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 (15,24 are untested)
+BGR15 & BGR16 MMX verions support dithering
+Special versions: fast Y 1:1 scaling (no interpolation in y direction)
TODO
-check alignment off everything
+more intelligent missalignment avoidance for the horizontal scaler
