	Path-local cubic approximation tolerance for the draw-time transform.

Variables
constexpr double	donner::geode::kFillCubicDevicePixels = 0.1
	Maximum cubic approximation error in device pixels and at identity scale.
constexpr double	donner::geode::kMinFillCubicTolerance = 1e-6
	Bounds approximation work; the device-pixel bound holds through 100,000x scale.

Detailed Description

Device-aware cubic-to-quadratic approximation for filled paths.

Function Documentation

double donner::geode::FillCubicToleranceFor ( const Transform2d & deviceFromLocal )

inline

Path-local cubic approximation tolerance for the draw-time transform.

Power-of-two scale buckets allow reuse during zoom. Minified paths retain the historical 0.1 tolerance; magnified paths are refined conservatively.

Parameters

deviceFromLocal Transform applied to the encoded path at draw time.
