gEDA-user: more on clipping

[David Carr]

Just curious,

How are you handling arcs in the polygons?  Are you using line segments 
as an approximation or are you actually using an arc primitive?  If you 
are using line segments, does the number of segments vary on the 
diameter or is it fixed?

Your 100K vertex comment made me curious.
