/* 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 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 editing or creation what zones that
|
|
* are really modified, and ones they are modified (changes, deletion or addition)
