  - move "if(const)" out from loops
  - supress duplicated computing

de0f2f4cca wmv1 slice_height != mb_height support 
encoding of slice_height != mb_height
1bit shorter wmv1 headers if bit_rate<50 !? ROTFL M$ is even more stupid than i thought
using dc of non intra blocks for dc prediction of wmv1 if bitrate < 129 && res < 320x240

494e409255 Assembly version of put_pixels. This is currently the function that
