However, if you don't use a font you get different defects for every
iteration.  Rendering small objects at low resolution requires understanding
device space and how to snap points into it.  If you use a procedure, you
have to do the snapping for each iteration; with a font, you only need to do
it once.  See Chapter 7, "Drawing Small Objects," in "Programming the Display
PostScript System with NeXTstep" for the basic ideas.
