  26. NOTES

  27. 

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

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

  30. 

  31. Supported output formats BGR15 BGR16 BGR24 BGR32

  32. BGR15 & BGR16 MMX verions support dithering

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

  34. 

  35. TODO

  36. more intelligent missalignment avoidance for the horizontal scaler

  37. bicubic scaler

  38. dither in C

  39. change the distance of the u & v buffer
