+// "integer" circle drawing functions.  These draw the limited

+// circle types provided by X and NT graphics.  The advantage of

+// these is that small ones draw quite nicely (probably due to stored

+// hand-drawn bitmaps of small circles!) and may be implemented by

+// hardware and thus are fast.

+

+// Probably should add fl_chord.
