vlc/plugins/yuv/transforms_yuvmmx.h
Sam Hocevar f56c4db12e . merged the YUV plugins in the same directory to avoid too much code
duplication
 . YUV transformations now use the new module API ; now only the vout
   and interface still depend on the old plugin API
 . changed TestMMX to TestCPU because we will be able to test for other
   specific extensions (3DNow, SSE) for the forthcoming IDCT we'll
   borrow to mpeg2dec (as usual :P)
 . don't show "hiding module" messages anymore except in debug mode
 . swapped C IDCT and Classic IDCT scores since the classic one seems
   to be faster ; anyway you should use the MMX one
 . fixed a Makefile bug under BeOS
 . tried to fix the cpuid code so that it compiles under BeOS (Polux, can
   you test it when you have time ?)
