I meant to say that the line that separates users of RIF from their
implementations is on the xdisp.c and dispnew.c level, i.e. on the
level that implements high-level Emacs display functions.  Drawing a
rectangle is not one of them, because the display engine cares about
text, images, and cursors, not about rectangles and pixels.
