82dd7d0dec * prefixication (due Kabi's request)
* generic optimization:
  - enable ALT and ALIGNED stream
  - move "if(const)" out from loops
  - supress duplicated computing
* first attempt to fix problem with strides

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
takes the most time, and it allows for more efficient unaligned access
and better control over memory latencies.

bb7d4939ba Implement put_pixels_clamped and add_pixels_clamped in Assembler. This
allows better scheduling of the memory accesses, and is portable among
all compilers.

code duplication, I'm currently working on the put/add variants, but I
did not get them to be as fast as the old method yet...
