/* 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)
