 Todo:
-	- Rotation degree snapping
 	- Only show rotation gizmo for one axis at a time
 	- Rotate mesh along mouse movement or show what the rotation is going to look like by using a wireframe version of mesh when rotating
 	- Match amount to be rotate with actual axes and the gizmo arc being drawn

 	* Rotate mode tool widget
 	* Complete rotate mode
