I have a scrollbar which, when moved, shows the user his 'viewport' on
a document (it renders the entire document on the screen and displays
a small box showing the bounds of his edit window).  I change the
display in a drag callback, which works just fine except that I would
prefer to change the display the moment he clicks on the scrollbar
slider (sort of like an Arm callback on a push button).  What is the
"proper" way to do this?
