Nudge Map (Wrapping) to Fix Map Resize Issue

[comods]

If you resize a map, you have no control over which corner it is anchored to, nor to anchor it to the center.
Currently you have to manually move every tile one by one, just to recenter it.

Please add 4 buttons:
Nudge Left, Right, Up, Down.
These will move all tiles over by 1 tile, and wrap the last row or column into the now empty first row or column.

Please add 2 buttons:
Select, Select-Wrapping (Or Toggles: [< > Wrap] [^v Wrap])
You already have copy, cut, paste but it always selects the whole map. There should be a Select button that allows you to select a subsection of the map like for sprites. Select-Wrapping would allow selecting and pasting that wrap off one side onto the opposite side.
