ScrollPaneController class

A controller for a ScrollPane.

A controller can only control one scroll pane at a time. Controllers can be attached to a scroll pane by setting them as the ScrollPane.controller.

When callers modify values in this class, the attached scroll pane will respond, and registered listeners will be notified.
