Wouldn't testing FRAME_RIF(f) instead of FRAME_WINDOW_P(f) make
more sense? At least, it would not rely on the fact that FRAME_RIF(f)
is supposedly non-NULL when FRAME_WINDOW_P(f) is true.
It'd make the code more "obviously safe".

I thought about that, but this way is more consistent with how the other
RIF procedures are called in xdisp.c (surrounded by a FRAME_WINDOW_P
check somewhere up the chain).
I don't have much of a preference, though; Eli, which would you prefer?
