>   class ImagemapRenderRegion : public RenderRegion

    Author:     Graham_Walmsley (Xara Group Ltd) <camelotdev@xara.com>
    Created:    15/4/97
    Purpose:    The render region for the imagemap filter.

                This render region has as a member an "Imagemap", which
                is a list of clickable areas.

                The render region works as follows. The Imagemap starts
                off empty. Then, whenever something is rendered into this 
                render region and there is a current WebAddressAttribute with
                a non-empty URL, a clickable area is added to the imagemap.
