Detailed Description

Apply a dash effect to the child geometry.

Follows the same semantics as SkDashPathEffect, with one minor tweak: when the number of intervals is odd, they are repeated once more to attain an even sequence (same as SVG stroke-dasharray: https://www.w3.org/TR/SVG11/painting.html#StrokeDasharrayProperty).
