Hi Jon-

If there is a mismatch between a computer's video capabilities and the 
size of the board being created, the user could work on the board in a 
lower resolution and then output a smoother gerber (that is consistent 
across computers).  This is how Solidworks handles 3d graphics.

This doesn't affect things like circles/tracks that use defined 
primitives in gerber output.  It only affects interpolated edges in 
polygons.  For other interpolations like rounded rectangles, we already 
use a higher (64) segments-per-circle count for the approximation in the 
output than we use for the on-screen representation.
