I want to zoom in and out of an image, and be able to pan. Ideally I
would like to control the zooming with a slider and the panning by
dragging, but I am open to other solutions, like zooming by clicking 
on buttons to predetermined steps  (the way it's done with maps) 
and panning with a slider. What I would like is a copy of a .fla 
document that does this to analyze and learn how it is done. 
If the document can be clarified with comments, great. 
But just the fla would be enough.
