Mike R: please sanity check SkPostConfig.h

Mike K: please sanity check Test.cpp and skia_test.cpp

Feel free to look at the rest, but I don't expect any in depth review of path ops innards.

Path Ops first iteration used QuickSort to order segments radiating from an intersection to compute the winding rule.

This revision uses a circular sort instead. Breaking out the circular sort into its own long-lived structure (SkOpAngle) allows doing less work and provides a home for caching additional sorting data.

The circle sort is more stable than the former sort, has a robust ordering and fewer exceptions. It finds unsortable ordering less often. It is less reliant on the initial curve  tangent, using convex hulls instead whenever it can.

Additional debug validation makes sure that the computed structures are self-consistent. A new visualization tool helps verify that the angle ordering is correct.

The 70+M tests pass with this change on Windows, Mac, Linux 32 and Linux 64 in debug and release.

/*
The sorting problem happens when the inital tangents are not a true indicator of the curve direction
Nearly always, the initial tangents do give the right answer,
so the trick is to figure out when the initial tangent cannot be trusted.
If the convex hulls of both curves are in the same half plane, and not overlapping, sorting the
hulls is enough.
If the hulls overlap, and have the same general direction, then intersect the shorter end point ray
with the opposing curve, and see on which side of the shorter curve the opposing intersection lies.
Otherwise, if the control vector is extremely short, likely the point on curve must be computed
If moving the control point slightly can change the sign of the cross product, either answer could
be "right".
We need to determine how short is extremely short. Move the control point a set percentage of
the largest length to determine how stable the curve is vis-a-vis the initial tangent.

angle is not treated as if it intersects at the same point.
There are several of options:
move the intersection of the right angle line to the coincident point (should 'near' do this?
construct another coincident pair from the right angle line to the coincident point
treat the intersection as simple and not coincident
