onMouseDown: If BoundingBoxTool got a hit result, switch to bounding box tool as the primary tool.
Else switch to the default tool.
Where should the move tool be handled? Might make sense on bounding box tool since whenever the bounding
box is active, move is possible
Shift button handling? If you shift click, bounding box tool wants to add it to the selection. But shape tools
probably don't.
- If shift is held down during mouse click, don't switch to the bounding box tool even if it gets a hit?
Then we can decide how to deal with it differently for different modes.
Alt button handling?
- Same as shift?
