* Tiling support for SkSweepGradientGravatar Florin Malita2017-08-01
| | | | | | | | | | | | | | | | | | Expand the sweep gradient definition to include a color stop angular range ([0, 360] by default). Color stop positions in [0,1] are mapped to this range, and drawing outside is controlled by a tile mode param. This is closer to the CSS gradients spec and allows us to use fewer color stops in Blink conic gradients. Impl-wise, the remapping is effected after t calculation, and before tiling.

* Add some raster pipeline perspective assertsGravatar Florin Malita2017-07-12
| | | | | | | | | | | | | | | | | | | | | I meant to add these when removing the guard, but since we landed without a guard, might as well do it now. A couple of things exposed by these asserts: 1) we need to also catch perspective in local matrices 2) we need to disallow burst mode with perspective Also tweak the predicate to hasPerspective() instead of explicit mask check.

* 2pt conical stage for focal-pt-on-edge caseGravatar Florin Malita2017-06-28
| | | | | | | | | | | | | | | | | | | When the focal point is on the edge of the end circle, the quadratic equation devolves to linear. Add a stage to handle this case. As a complication, this case can produce "degenerate" values: 1) t == NaN 2) R(t) < 0 For these, we're supposed to draw transparent black - which means overwriting the color from the gradient stage. To support this, build a 0/1 vector mask in the context, and apply it post-gradient-stage.
