/* These functions are relative to undo redo function, when zones are involved.
* When a zone outline is modified (or created) this zone, or others zones on the same layer * and with the same netcode can change or can be deleted * This is due to the fact overlapping zones are merged * Also, when a zone outline is modified by adding a cutout area, * this zone can be converted to more than one area, if the outline is break to 2 or more outlines * and therefore new zones are created * * Due to the complexity of potential changes, and the fact there are only few zones * in a board, and a zone has only few segments outlines, the more easy way to * undo redo changes is to make a copy of all zones that can be changed * and see after zone edition or creation what zones that are really modified, * and ones they are modified (changes, deletion or addition)*/
