What transition are you using -- one of the motion-based options like push
or scroll? If yes, one solution could be to use the move command or
something like AnimationEngine to physically move background groups left
and right (or up and down). But since we're talking about the entire
width/height of the card, that might be a lot of screen to update, which
could bog down on an underpowered device.
