This procedure returns whether there is a selection for the

specified image. If there is one, the upper left and lower right

corners of the bounding box are returned. These coordinates are

relative to the image. Please note that the pixel specified by the

lower righthand coordinate of the bounding box is not part of the

selection. The selection ends at the upper left corner of this

pixel. This means the width of the selection can be calculated as

(x2 - x1), its height as (y2 - y1).</p>
