The scroller (a transform) of a scrollPane is driven by the scrollBar. The scroll values vary from 0.0, meaning zero offset to 1.0 meaning sufficient offset such that the bottom of the scrollable material appears halfway down the pane. The total distance to achieve this range is called the totalScrollRange.

	addCustomMenuItems:hand: Add morph-specific items to the given menu which was invoked by the given hand. This method provides is invoked both from the halo-menu and from the control-menu regimes.
	getMenu: Answer the menu for this text view, supplying an empty menu to be filled in. If the menu selector takes an extra argument, pass in the current state of the shift key.

	pane events	top
	handlesMouseDown: Do I want to receive mouseDown events (mouseDown:, mouseMove:, mouseUp:)?
	handlesMouseOver: Do I want to receive mouseEnter: and mouseLeave: when the button is up and the hand is empty? The default response is false, except if you have added sensitivity to mouseEnter: or mouseLeave:, using the on:send:to: mechanism.
	keyStroke: If pane is not full, pass the event to the last submorph, assuming it is the most appropriate recipient (!)
	mouseDown: Handle a mouse down event. The default response is to let my eventHandler, if any, handle it.
	mouseMove: If pane is not full, pass the event to the last submorph, assuming it is the most appropriate recipient (!)
	mouseUp: If pane is not full, pass the event to the last submorph, assuming it is the most appropriate recipient (!)
	rejectsEvent: Return true to reject the given event. Rejecting an event means neither the receiver nor any of it's submorphs will be given any chance to handle it.
