…rom PolyLineWidget Refactors PolyLineWidget so it can support having a max number of points. Makes AngleWidget and DistanceWidget inherits from PolyLineWidget by limiting their maxPoints to 2 and 3. Remove a lot of duplicate code between Angle and Distance widgets.

what if you were simply dragging a point, should you also "lose focus" ?

you need to document that setting maxpoint at run time won't reduce the number of points

Context
Angle and Distance widgets were basically PolyLineWidgets but with a hard-coded limit on their number of points, and a method to compute an angle/distance. The
behavior.jsfile was almost the same between the 3 widgets, which was a potential source of bugs or difference on behaviors.Results
behavior.jsandstate.js) in Angle and Distance widgets.Changes
