A point is a unit of measure, sort of like a cubit only smaller. It does
not imply integerness.

p.s. The point as a unit of measure predates Postscript by about 100 years.
Cubits go back a bit further, and are a well-defined unit of measure
in same sense that the size of a 17 inch monitor is well-defined display
size. Thus the cubit would be a good standard unit of measure for Squeak
printing and display sizing. I propose milliCubits in the interest of
notational simplicity, such that a 12 point font would be represented
internally in Squeak as about 8 or 9 milliCubits, depending on your
screen resolution.
