Don't start subdividing active edges until we're sure an entire B-quad
...
will be emitted.
Otherwise it messes up the parity.
Fixes the bottom curve of the lowercase "p" in Open Sans when rendered
with Loop-Blinn.

Replace the implicitization algorithm for curve intersection with a
...
simpler one based on binary search and the quadratic formula.
This does a better job avoiding floating point error and improves the
rendering of the tiger.
