/**
* A container class which implements automatic horizontal and/or
* vertical scrolling for a single child component. The display
* policy for the scrollbars can be set to:
* <OL>
* <LI>as needed: scrollbars created and shown only when needed by scrollpane
* <LI>always: scrollbars created and always shown by the scrollpane
* <LI>never: scrollbars never created or shown by the scrollpane
* </OL>
* <P>
* The state of the horizontal and vertical scrollbars is represented
* by two <code>ScrollPaneAdjustable</code> objects (one for each
* dimension) which implement the <code>Adjustable</code> interface.
* The API provides methods to access those objects such that the
* attributes on the Adjustable object (such as unitIncrement, value,
* etc.) can be manipulated.
* <P>
* Certain adjustable properties (minimum, maximum, blockIncrement,
* and visibleAmount) are set internally by the scrollpane in accordance
* with the geometry of the scrollpane and its child and these should
* not be set by programs using the scrollpane.
* <P>
* If the scrollbar display policy is defined as "never", then the
* scrollpane can still be programmatically scrolled using the
* setScrollPosition() method and the scrollpane will move and clip
* the child's contents appropriately. This policy is useful if the
* program needs to create and manage its own adjustable controls.
* <P>
* The placement of the scrollbars is controlled by platform-specific
* properties set by the user outside of the program.
* <P>
* The initial size of this container is set to 100x100, but can
* be reset using setSize().
* <P>
* Scrolling with the wheel on a wheel-equipped mouse is enabled by default.
* This can be disabled using <code>setWheelScrollingEnabled</code>.
* Wheel scrolling can be customized by setting the block and
* unit increment of the horizontal and vertical Adjustables.
* For information on how mouse wheel events are dispatched, see
* the class description for {@link MouseWheelEvent}.
* <P>
* Insets are used to define any space used by scrollbars and any
* borders created by the scroll pane. getInsets() can be used
* to get the current value for the insets. If the value of
* scrollbarsAlwaysVisible is false, then the value of the insets
* will change dynamically depending on whether the scrollbars are
* currently visible or not.
