I know but I just wanted to show you that there were a simple fix to
this problem for the MMX stuff. My point is really that there is a
difference in alpha output that depends on if you have --enable-
swscaler or not in the img/sws routines. I would like to start with a
discussion if it should be 0 or 0xff when converting from a non alpha
format. Backwards compatibility is also an issue for me as the
original img_convert produces 0xff and the new swscaler produces 0.
Then if we can solve this, I am sure there are plenty better
programmers than me to help me with this fix to make it complete.
