cd92221a8d Just a comment update, replacing a FIXME to reflect the new expectation of
how altivec_yuv2packedX is supposed to be used

cbddd5dfc6 Fix vec_clip for gcc's that don't handle (vector signed short){16} according
to spec; also convert a few vec_splat's to vec_splat_{s,u}*

d33d485e83 Move the v{Y,C}CoeffsBank vectors into the SwsContext, filling them in just
once when the scaler is initialized, instead of building them and freeing
them over and over. This gives massive performance improvements.

7d20ebffdf Correct RGB vs. BGR confusion, the macros vec_mstrgb24 and vec_mstbgr24 each
do the opposite of what they say.
The vec_mstrgb24 and vec_mstbgr24 macros should be opposites and not perform
the same things.

3845b56dd1 altivec_yuv2packedX() ignores the requested output format and unconditionally
outputs RGBA. This patch supports 6 output formats and prints an error message
if it is asked to provide an output format it is not capable of.
