/**
   This MMX assembler is my first assembler/MMX program ever.
   Thus it maybe buggy.
   Send patches to:
   mvogt@rhrk.uni-kl.de

   After it worked fine I have "obfuscated" the code a bit to have
   more parallism in the MMX units. This means I moved
   initilisation around and delayed other instruction.
   Performance measurement did not show that this brought any advantage
   but in theory it _should_ be faster this way.

   The overall performanve gain to the C based dither was 30%-40%.
   The MMX routine calculates 256bit=8RGB values in each cycle
   (4 for row1 & 4 for row2)

   The red/green/blue.. coefficents are taken from the mpeg_play 
   player. They look nice, but I dont know if you can have
   better values, to avoid integer rounding errors.
   

   IMPORTANT:
   ==========

   It is a requirement that the cr/cb/lum are 8 byte aligned and
   the out are 16byte aligned or you will/may get segfaults
