swap_src_dst -> move_src_dst

We thought it'd be handy to have swap_src_dst so that it could be used
either to move dst into src or src into dst.  Turns out, we already have
a stage that moves dst into src (called "dst", the dst blend mode), so
there's really no reason to have swap_src_dst over the strictly more
efficient move_src_dst.

swap_src_dst is typically 12 register moves, where move_src_dst is 4.
