        How the demo works:
        
        Under the Draw menu, there are three options:
        
        *Draw Test: will put up a picture of a bunch of randomly generated
        objects, of each kind supported.
        
        *Draw Map: will draw a map of the world. Be patient, it is a big map,
        with a lot of data, and will take a while to load and draw (about 10 sec 
        on my 450Mhz PIII). Redraws take about 2 sec. This demonstrates how the
        performance is not very good for large drawings.
        
        *Clear: Clears the Canvas.
        
        Once you have a picture drawn, you can zoom in and out and move about
        the picture. There is a tool bar with three tools that can be
        selected. 
        
        The magnifying glass with the plus is the zoom in tool. Once selected,
        if you click the image, it will zoom in, centered on where you
        clicked. If you click and drag the mouse, you will get a rubber band
        box, and the image will zoom to fit that box when you release it.
        
        The magnifying glass with the minus is the zoom out tool. Once selected,
        if you click the image, it will zoom out, centered on where you
        clicked. (note that this takes a while when you are looking at the map,
        as it has a LOT of lines to be drawn. The image is double buffered, so
        you don't see the drawing in progress)
        
        The hand is the move tool. Once selected, if you click and drag on the
        image, it will move so that the part you clicked on ends up where you
        release the mouse. Nothing is changed while you are dragging. The
        drawing is too slow for that.
        
        I'd like the cursor to change as you change tools, but the stock
        wxCursors didn't include anything I liked, so I stuck with the
        pointer. Please let me know if you have any nice cursor images for me to
        use.
