Detailed Description

Manage the construction of a circular arc though sequential setting of critical points: center, arc start and arc end.

The manager is driven by setting cursor points, which update the geometry, and optionally advance the manager state.

Interfaces are provided to return both arc geometry (can be used to set up real arcs on PCBs, for example) as well as important control points for informational overlays.
