The question is, how are we going to tell paint ops to use a different
(RGBA) colorspace instead of a value returned by
KisPaintDevice::colorSpace() that will return RGB in this very case? That
is the point where Boud doesn't agree. I have already got a small draft of
a composite op you described and it works quite well. But we need some way
for the paint ops to prepare data with that alpha channel for it. That is
the problem.
