fix line intersect divide by zero

Test filinmangust14 exposes two problems:
- finding top of contour can expose divide by zero
- joining partial contour results can add diagonal

The latter makes the test return the wrong result,
and has not been seen in other tests. The fix
is to join disconnected contours by only following
the contours provided as input. Working on that.

The former bug is more straight-forward; just
don't try to compute axis-aligned intersection
if the denominator is zero.

All existing tests prior to the new one work
with this change.
