   JSX:enhancd2.js:enlargeImg

   Opens a dependent browser child window containing an (enlarged) image.
   A primary button mouse click on the image or the window closes the
   window.

   Arguments:

   sImageURL   Required. URL of the (enlarged) image.
   sCaption    Optional. Caption of the browser child window.
               If not provided, sImageURL will be used as caption.
   iWidth      Optional. Width of the browser child window in pixels.
               If not provided or 0, the window will be resized
               to fit image width.
   iHeight     Optional. Height of the browser child window in pixels.
               If not provided or 0, the window will be resized
               to fit image height.
   bCenter     Optional. If true, the window will be centered on
               the screen.
               Note: Use with caution! Not all desktops return
               the correct position for the centered window.

   Return value:

   Always false which allows
   <a href="..." ... onclick="return enlargeImg(...);">
