I guess I'll have to take your word for it :) But in all the
tests I ran (which, again, were rather few) no problems arose. Also,
the code logic for the c and mmx versions are not the same, so it's
unlikely
that one would encouter the same problem with both (assuming you had
problems with both).
Note that the new blend functions are much more strict about
wether or not an image (src or dst) has-alpha.

Yeah, but... we've been down this road once before... :)
