x264 | branch: master | David Wolstencroft <wolstencroft at alum.rpi.edu> | Sun Dec 14 10:47:28 2008 +0000| [918ff3c6a33e170655b61af85f8955ec5590fff8] | committer: Guillaume Poirier 

Fix visual corruption when picture width was not mod 32.
The previous Altivec implemention of mc_chroma assumed that i_src_stride was always mod 16.
