fca0f0e59f * removed MANGLE from macros for setting constants 
* using MOVQ_WONE/MOVQ_BFE as two instruction instead of static memory value access
  as its always faster
* PAVGB_MMX macro is using now mm6 -> mm7 is unmodified
* replaced original pixels_xy2_mmx with new faster and equal implementation
* replaced usage of mm7 for other then ZERO contstant in _rnd & _avg file with mm6

ff9657069a * using unrolled loops seems to help to MMX Celerons 
* calculating average in parallel to use two MMX units
* disabled xy2 put code - it's producing rouding errors

6aa6ea8e11 * reenabled original xy2 put routine - rounding error is really bad with 
the new code
* added PAVGP macros for parallel processing to safe few more cycles on
  celerons

91abb473fb * code with new PAVGB for MMX only CPU splited into separate file 
and being compiled in the same way as _avg.h
* PAVG_MMX macros accept also output parameter
* implemented faster put_pixels_xy2, but it has slightly smaller precission.
  But there is not visible difference in the image quality - might be eventualy
  easily switched back (#if 0 #endif)- please check
