Would a patch for swscaler that basically just takes the existing C code
(with no SSE implementation) be acceptable?  I would need to create a
new image format, would IMGFMT_YV12A be ok?  One problem is that YV12A
is comprised of 5 planes, but there seems to be a general assumption in
the swscaler code that all the src/dst are an array of 3 planes.  Would
this end up being a problem?

Cheers,
Jason.
