Steps to activate:
1 - Select an object
2 - In the transform box, click and hold "Scale"
3 - Drag vertically to select the incremental precision
4 - Drag horizontally to apply increments of the selected precision
Issues:
- Releasing the mouse on top of the canvas will also trigger a "mouseup"
event on the canvas (since it listens to the window, not the canvas) and
deselect the object.
