Yes. From a bitmap perspective, anyway.

And certainly circles, even from a vector computer graphics point of 
view are  actually polygons, not circles.  Which is really my problem..

And is directly related to dynamic zooming.  I am in fact attempting to 
make my algorithm for converting a representation from a circle (i.e. 
polygon)  to a line and back again sensitive to the  actual zoom level.

At some definition of local, the circle becomes a line.

Summer must be over .  I have time for this kind of fun again.
