Edit behavior for ELLIPSE and ELLIPSE_ARC shapes.
Closed ellipse: 3 handles (center, major-axis endpoint, minor-axis endpoint).
Elliptical arc: 5 handles (the above + arc start + arc end).
Drag semantics:

Finalize the edit operation.
(optional)
This is called once, after the user has finished editing a point (e.g. released the mouse button).
| aPoints | The final positions of the edit points. |
| aCommit | The commit object to use to modify the item. |

Get the 45-degree constrainer for the item, when the given point is moved.
Return std::nullopt if not, and the caller can decide.
If you want to actively disable constraining, return the aEditedPoint position.

overridevirtual |
Update the item with the new positions of the edit points.
This method should all commit and add to the update list anything that is NOT the parent item of the EDIT_POINTs. For example, connected lines, parent tables, etc. The item itself is already handled (most behaviors don't need more than that).
| aEditedPoint | The point that was dragged. You can use this to check by address which point to update. |
| aPoints | The new positions of the edit points. |
| aCommit | The commit object to use to modify the item. |
| aUpdatedItems | The list of items that were updated by the edit (not only the item that was being edited, but also any other items that were affected, e.g. by being conneted to the edited item). |

Update the list of the edit points for the item.
Be very careful not to overrun the list of points - this class knows how big they are because it made them in the first place.
If item has changed such that that number of points needs to change, this method has to handle that (probably by clearing the list and refilling it).
If the behavior itself must change (for instance, a rectangle is non-cardinallly rotated to a polygon), the method should return false.
