Ah, yes, I totally forgot that!

AFAIK, a single Premultiply(out) at the end should be sufficient.

Edit: But since this implementation don't have a working alpha channel, Premultiply should be removed completely.

This algorithm is not "the fastest", but reasonably fast and works well.

Best regards,
Oblivion

Ah, but then it should probably start with "unmultiply"...
