In my judgment, nothing else is needed. Most functions just need the
type of the frames on display, which can be gleaned from any of the
possible argument types. The other need the screen used by the
display, which again can be gotten from any argument type.
IOW, these arguments serve as proxies to the information needed by the
functions.
