Two ZUN bugs in a single function call! These end up causing
effectively random sprite pixels to disappear during the transition to
the boss clear tally screen, if the boss was killed while any shootout
lasers were on screen. And once again, one of those bugs would have
been a non-issue with strong enough typing…
Oh well, that's all there is to this class.
