The caller, yes.

fullscreen (maybe renamed) should do what it does now, IMO. I fail to
see the point of having a function that respects the classic sb but not
the custom sb. Where would the be useful? You surely want to either be
ultimately fullscreen (0,0,LCD_WIDTH,LCD_HEIGHT), or let background
drawings happen.

That's what set_defaults() does. Yet I'm skeptical about calling it from
the WPS. The WPS should really be as fullscreen as possible (i.e. so
that it just doesn't draw over the sbs/classic statusbar) since it
doesn't draw any list and the UI vp doesn't make any sense due to the
customizability. That's what _set_fullscreen() achieves.

It's not simply a hint.
