Comment (by strk):

 2 and 3 would make sense as being a "minimum".
 6 would be just arbitrary. Accuracy for an arc
 really depends on the arc size.

 6 segments on a 1e-15 degrees arc could be too much
 (even 2 segments could be too much in that case).

 If you want more segments in a circle we could
 set not a minimum number of segments per arc but
 per arc-or-quadrant. So if the minimum is 2 you
 would have at least 8 segments for a ricle (2*4)
