Yes - anything that blocks the main thread is going to stall the
animation. I imagine there are quite a few places where that is going
to happen - although I haven't seen it for new screens or popups.

I don't think either of these cases really need this particular
functionality. It just needs to be handled in the existing code.

For the Ken Burns effect, the code just needs to handle a slow zoom
effect into a particular spot in the photo.

For coverart etc, it needs some thing akin to the existing
fade/transition between 2 screens. Not sure how hard that is to
implement.
