* fix circular dashingGravatar caryclark2016-01-19
| | | | | | | | | | | | | | | | | | | | | Path measure cannot use the same code approach for quadratics and cubics. Subdividing cubics repeatedly does not result in subdivided t values, e.g. a quarter circle cubic divided in half twice does not have a t value equivalent to 1/4. Instead, always compute the cubic segment from a pair of t values. When finding the length of the cubic through recursive measures, it is enough to carry the point at a given t to the next subdivision. (Chrome suppression has landed already.)

* handle large conic strokes betterGravatar caryclark2015-05-19
| | | | | | | | | | | | | | | | | | | | A stroked conic computes the outset quad's control point by computing the intersection of the quad's endpoints. If the the denominator used to compute the scale factor for the control point is small, check to see if the numerator is also small so that the division stays bounded. Also clean up error returns and internal function calls to simplify the code. Additionally, remove comic max curvature (unimplemented) and call extrema functions instead to handle cases where the conic is degenerate or is a line.

* This uses quad approximations of the outer and inner paths describing a ↵Gravatar caryclark2015-02-20
| | | | | | | | | | stroke. Cubics and conics' thick strokes are approximated with quads as well. The approximation uses a similar error term as the fill scan converter to determine the number of quads to use. This also updates SampleApp QuadStroker test with conics, ovals, and stroked text.

* update sampleapp for stroking experimentGravatar caryclark2015-02-18
Add RotateCircles3 back as better-named QuadStroker. Switch pathfill test to call skia before draw instead of in initializer to avoid triggering debugging breakpoints. Review URL: https://codereview.chromium.org/912273003
