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. Review URL: https://codereview.chromium.org/13094010 git-svn-id: http://skia.googlecode.com/svn/trunk@8553 2bbb7eff-a529-9590-31e7-b0007b416f81
