============================================================================================ On creation of a constraint from the UI (toolbar/menu): 1. if a PointOnObject constraint preexisted the addition of an edge-to-edge tangency, substitute it with a point-to-edge tangency. 2. if an edge-to-edge tangency preexisted, addition of a PointOnObject results in a substitution of the edge-to-edge tangency with an edge-to-curve tangency. Bonus: - Refactor of this with preexisting coincident+tangent substitution. - Activate both substitutions in continuous constraint addition mode.
