Screens get an invisible mousearea that reports the pointer entering and leaving without taking clicks. datetime.date/datetime/timedelta support construction and date arithmetic. dir() lists the game's variables, renpy.style.rebuild() is a no-op, and renpy.image_size answers only for pictures the browser already holds (otherwise an IOError the game can catch).
