 #   Get correct sizing parameter for an image given  
 #   it's initial ht. and wid.  This allows sizing of  
 #   images that are generated on-the-fly (e.g. gnuplot)  
 #   as well as serving as a utility for image_size.

 #  Parameter:  
 #        height_param  
 #        width_param    - Initial picture dimensions.  
 #        scaling        - A scale factor.

 #        depth,  
 #        cis           - The usual xml stuff ???

 # Returns:  
 #   height, width   - new dimensions.
