Class description
A class implementing the draw-boundary and draw-interior generic words by delegating to an object in one of four slots which depend on the state of the button being drawn:

•	plain - the button is inactive
•	rollover - the button is under the mouse
•	pressed - the button is under the mouse and a mouse button is held down
•	selected - the button is selected (see checkbox)
•	pressed-selected - the button is selected and a mouse button is being held down (see checkbox)

The <roll-button> and <border-button> words create button instances with specific button-pen s.
