just shows how to use the basic face and effects to perform, relatively 
fast transforms, instead of using the Draw commands, which can provide 
more quality and options, but at a cost in speed.



you can change the rate of animation by changing the number of steps 
in the animation.


I also added a scrollbar to show how to tie up the effect to an interactive 
control.


This script was originally built to help a REBOLer who needed to 
provide scrolling maps of his city within a firefighter application 
which was use to locate incidents based on coordinates and point and click on different res maps.  (a bit like google maps I guess).
