compare degenerates with tolerance

Conics with very large w values can
be approximated with two straight lines.

This avoids iterating endlessly in an
attempt to create quadratics with unstable
numerics.

Check to see if the first chop generated
a pair of lines within the default
point comparison tolerance.
