// 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
