"Change Set:		ExtendedEventHandler
Date:			27 March 2000
Author:			Stephan Rudlof

This changeset contains an extended event handler ExtEventHandler. It
generates and handles
	mouseEnterBorder, mouseLeaveBorder,
	mouseEnterBorderDragging, mouseLeaveBorderDragging

There is given an example for viewing the new behavior: Just open a
Transcript and evaluate
	DAndDAlignmentContainerMorph new openInWorld

To have symmetrical behavior there is needed a small change of
HandMorph>>handleMouseUp: (look for a comment there), which doesn't seem
to have an effect to the current system: At least I haven't seen any so

Changes in EventHandler are just for less code in ExtEventHandler and
don't change any functionality.

Because I'm new in morphic I'm very interested in any feedback!
