Cary Clark 9d6049a96f fix pathops bug 8380 
Paths to intersect have two nearly coincident cubics. Where they
cross, the intersection error makes the curves start at slightly
different points. To sort the intersection, one curve is translated
to the start of the opposite point, moving it from one side to the
other, introducing a winding error.

The fix looks for that error in a very tiny range (enlarging that
range causes other tests that now pass to fail). This fix is very
fragile and points to the need for a better approach than sorting
angles to find winding values, as documented in the bug.

Also renamed some angle functions to show that they operate only
on lines and not general curves.

All tests pass with this fix:
./out/release/pathops_unittest -V -x
./out/debug/pathops_unittest -V -x
