16cfe40276 allow tests to optionally use multiple threads
modify threaded path ops tests to check

Background: this CL came out of a conversation with Eric where I learned that 10s of machines host 100s of bots. Since the bot hosting tests may be shared with many other tasks, it seems unwise for path ops to launch multiple test threads.

The change here is to make launching multiple threads "opt-in" and by default, bots can run path ops in a single thread.

0361032c0b path ops work in progress
fix bugs in tests on 32 bit release

Most changes revolve around pinning computed t values
very close to zero and one.

818b0cc1b8 Add implementation of path ops
This CL depends on
https://codereview.chromium.org/12880016/
"Add intersections for path ops"

Given a path, iterate through its contour, and
construct an array of segments containing its curves.

Intersect each curve with every other curve, and for
cubics, with itself.

Given the set of intersections, find one with the 
smallest y and sort the curves eminating from the
intersection. Assign each curve a winding value.

Operate on the curves, keeping and discarding them
according to the current operation and the sum of
the winding values.

Assemble the kept curves into an output path.
