Scale tool

For the gamepad we can use the move tool to scale also, by grabbing and using up/down on the dpad. However, this makes it quite difficult to scale by very subtle increments because it's all-or-nothing.

If we had an analogue way of doing this, like you can with the moves. A separate "scale" tool could be added, letting us use R2 on an object to scale it up. Pull it lightly, and it'll scale very slowly. Pull it full and it'll scale faster.

And we could toggle between increasing and decreasing scale in the same way we can for adding/removing effects, colours, etc.
