Issue Summary

A very simple user experience issue / bug. when flipping a selection either on the X or Y axis, this command is not undo-able / redo-able.

Expected Results

Due to the nature of art, most if not all drastic changes in a drawing should be undoable. Flipping a drawing changes it's direction and sometimes artists try to find the best way to present them.

Note: This is not a critical bug by any means, you can flip the drawing again instead of undoing, but from a functionality standpoint all of these commands should be undo-able.

Steps to reproduce

1. Draw something
2. Enclose it with the selection tool
3. Go to Edit > Selection > Flip X / Y
4. Press Ctrl + Z or go to Edit > Undo
