For example that of getting the screen dimensions of a window.  Have a
look at x_real_pos_and_offsets to get an idea of the tribulations needed
to do that for an Emacs frame.  These are by far the most complicated
operations we do in the X specific code and I have reports that we still
do not get the right results everywhere.
