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.

add a failing Line.intersect(Line) test
...
These two lines are parallel but do not intersect. Line.intersect()
finds an incorrect intersection.

Before this commit the `t = k / steps` math is done with integers,
which always results in `t = 0`.
This commit forces the math to be done with floating-point numbers,
which results in the progression of `t` values we want.
