plug in the accelerated one, even if the destination pixmap is
currently offscreen. This was a leftover from when kaa originally got
accelerated offscreen pixmap support, and its only concievable use was
to avoid a little overhead on ops to in-system pixmaps that weren't
going to get migrated. At this point, we probably care more about just
getting everything accelerated that we easily can, which should happen
with the new migration support.
