Implement line editing (#1616)

Browse source 
* implement line editing

* line editing with rotation

* ensure adding new points is disabled on point dragging

* fix hotkey replacement

* don't paint bounding box when creating new multipoint

* tweak points style, account for zoom and z-index

* don't persist editingLinearElement to localStorage

* don't mutate on noop points updates

* account for rotation when adding new point

* ensure clicking on points doesn't deselect element

* tweak history handling around editingline element

* update snapshots

* refactor pointerMove handling

* factor out point dragging

* factor out pointerDown

* improve positioning with rotation

* revert to use roughjs for calculating points bounds

* migrate from storing editingLinearElement.element to id

* make GlobalScene.getElement into O(1)

* use Alt for adding new points

* fix adding and deleting a point with rotation

* disable resize handlers & bounding box on line edit
