In Sculpt Mode, the UI should update when holding Ctrl to invert the tool
Open, NormalPublic

Description

In Sculpt Mode, users can hold Ctrl to invert the effect of the current tool. However, both the tool settings + and - buttons, as well as the color of the brush cursor, don't update to reflect that you've inverted the effect.

Both of these should update their state when the user holds Ctrl.

I wouldn't really advise trying to implement the +/- button changing, that's going to be very messy in the current system. Just the cursor seems like a good indication already.

@Brecht Van Lommel (brecht): It may be messy in the code, but it would serve as a nice indication that the tool is inverted. Many other apps do this - they update the settings when you hold a key, and the UI updates to reflect it.

Maybe the color of the brush cursor could be the first step, and we could later find a better way to implement the other UI items so they reflect the current state.
