Just for the reference, since I have not seen it mentioned yet in
response:

	"How Many Ways Can You Draw a Circle?"
	Jim Blinn
	IEEE Computer Graphics and Applications
	August, 1987

It is not quite what is wanted, but a good collateral reference.
(Jim Blinn's articles in each issue of this journal are absolutely
required reading.)
