hui su 43bd895879 Make gif transparent color to be transparent black ...

Change it from transparent white to transparent black, which matches
the transparent color assumed in Webp dispose-to-background method.

Also pre-multiply background colors before comparison in anim_diff,
just as what is done with regular pixel values.
