// The tool UI has 4 purposes:
//		1) Create the menu bar and client area (lies under the menu bar)
//		2) Forward all mouse messages to the tool workspace so action menus work
//		3) Forward all commands to the tool system so all smarts can reside there
//		4) Control the size of the menu bar + the working area
