* Construct round rects with perpendicular tangents.Gravatar commit-bot@chromium.org2013-11-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The round rects are constructed as before out of quadratics, but without fudging the control points. Instead, the mid on- curve point is nudged slightly outward to prevent the convexity test from failing. The convexity test now includes an error term for sign inequality after computing the cross product of the control lines. When the control points are represented as vectors, the number of bits of precision may be greatly reduced. Account for this by passing the number of bits available from the original control point values into the equality check. Making round rect construction lines perpendicular improves the chances of success when path ops encounters clips. No new tests are needed -- this change is exercised by the convex Path unit tests and the gm tests arcofzorro and hairlines.
