| This determines whether the first time the method is ran whether it will do anything.
In the case of the MoveVertex behaviour the vertices are moved
little by little, pixel by pixel often. So undoing and redoing all that would be
pointless. For those cases this command has a RedoUndoOnly parameter so that when the command
is sent to the map it does nothing. But once undo is called redo will still work. If this is false then
it will operate normally.
Parameters: redoUndoOnly - |
