Scrolling Functionality for Large Graphics

      A graphical user interface for scrolling images, plans or data
which are bigger than their viewable part on the computer screen.
This method allows the user to set an anchor point on the computer
screen and  scroll right, left, up or down from this point.  It also
preserves the  anchor point on the computer screen.

      Viewing an image, a plan or data which is bigger than the
computer screen causes the user to use the scroll bars or the
overview functionality to navigate on an application.  Often, when
the user wants  to scroll the current viewable part by the
width/height of the computer  screen, it becomes complex to do.

      This new functionality allows the user to scroll by one
viewable width/height by keeping the anchor point part of the
previous view as part of the new view by adding two extra pushbuttons
as part of  the standard scroll bar.

      By adding extra pushbuttons on each side of the regular scroll
bar to allow the user to scroll by the view width/height and by
keeping the last visible part of the previous view on the display
edge of the new view.  This way, when the user wants to follow a
plan, he can press  the new pushbuttons and this action keeps on the
display view the last  visible part of the plan plus the new visible
part.  It saves the user  pressing multiple times the scroll bar
pushbuttons or having to use the  overview functionality to scroll to
this position.
