Find the bounding box of the current selection.
</p>
<p>
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).
