Sebastian Kuzminsky b37e74f5f3 Update Path.area to work with Arc segments (#65)
* add some tests of Path.area()

These tests currently fail because area() doesn't deal with Arc segments.
Fix in the following commit.

* make Path.area() approximate arcs

Fixes #37.

* Path.area(): fixup tabs/spaces for python3

* added asin to imports

* added asin to imports

Sebastian Kuzminsky 2feb3c92b5 Arc line intersect, 3rd try (#64)
* add Line.point_to_t() and tests

These tests don't print anything while they run, and they use use the
assert() helpers from the unittest module.

* add Arc.point_to_t() and tests

These tests don't print anything while they run, and they use use the
assert() helpers from the unittest module.

* add a bunch of failing arc/line intersection tests

This commit contains a bunch of failing arc/line intersections that I
and other people have run into.

These tests don't print anything while they run, and they use use the
assert() helpers from the unittest module where possible.

All these tests are fixed in the following commit.

* better implementation of Arc.intersect(Line)

Fixes mathandy/svgpathtools#35.

This commit fixes all the arc/line intersection test cases added in the
previous commit.

This implementation provides special handling in Arc.intersect() when
`self` is a non-rotated Arc and `other_seg` is a Line.  In this case
it uses the straight-forward closed-form solution to identify the
intersection points.

Rotated Arcs and Arcs intersecting with non-Line objects still use
the pre-existing intersection code, that part is totally untouched by
this commit.

Sebastian Kuzminsky 89d9acf06e 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.

Sebastian Kuzminsky fc34d2c4cf 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.
