Line.intersect(Line): fix a "miss some intersections" bug
...
Negative numbers are allowed in the denominator, what we really want to
avoid is near-zero denominators.

deal with float rounding error in Line.intersect(Line)
...
This commit fixes #41 .
In the test case added in the previous commit, two non-intersecting lines
are very nearly collinear, but float rounding errors lead to incorrect
intersections reported.
This commit makes Line.intersect() treat denominators below 1e-9 as 0,
to make it more accepting of float rounding.

Arc: Handle round-off issue with acos()
...
math.acos raises outside of valid range [-1, 1]. Handle round-off errors
gracefully by using `round()` here too.
