Until last night, I was under the impression that the switch to
swscale would only be done when the mmx parts were separated from the
main code, and an lgpl version could be built.  It would appear that I
was mistaken, if not misled.  Making the scaler and colourspace
converter gpl is effectively making all of ffmpeg gpl.

I've already explained why I don't do any work on swscale: I cannot
comprehend the code, and every time I've attempted to do anything with
it, I've ended up breaking something.

Michael wants swscale to be the default/only scaler.  It is thus his
duty to get it into a shape worthy of that position.  He's made a good
start, but the work is far from complete.  Luca has posted some
patches to further clean it up, so why doesn't Michael work with him
on getting these committed?  Then we'd have an lgpl swscale (albeit
unaccelerated), and nobody should have any objections to dropping the
old scaler entirely.

I'd even go as far as suggesting we treat libswscale as a new
submission, and subject it to all the scrutiny that has come to be
standard procedure in FFmpeg.
