PathBuilder

Remarks

⚠ Curves are kept as curves. Nothing here flattens a Bézier into line segments, and that is deliberate: how finely to flatten depends on how large the curve will be on screen, which is a device scale this does not know. Flattened here, a path built once and drawn at two zoom levels is faceted at one of them or over-tessellated at the other, and nothing downstream can recover the curve to do better.

Owned by the caller and reusable — Clear keeps the capacity. A control that draws every frame should keep one in a field rather than making a new one, for the same reason any other per-frame allocation is worth avoiding.
