  25. NOTES

  26. 

  27. known BUGS with known cause (no bugreports please!, but patches are welcome :) )

  28. horizontal MMX2 scaler reads 1-7 samples too much (might cause a sig11)

  29. 

  30. Supported output formats BGR15 BGR16 BGR24 BGR32

  31. BGR15 & BGR16 MMX verions support dithering

  32. Special versions: fast Y 1:1 scaling (no interpolation in y direction)

  33. 

  34. TODO

  35. more intelligent missalignment avoidance for the horizontal scaler

  36. bicubic scaler
