Ok, some more questions.  I see the issue with imshow(r,g,b).  Legacy code 
converts those r,g,b components to a color map.  That's not required and 
probably not preferred.  Gnuplot can handle r,g,b components.

Should there be a general function, say __img__.m to handle all the cases of 
imshow, image, and imagesc?

I guess a more basic question is should there be another "image" type, e.g., "rgbimage", 
or do both fall under the class "image"?  I.e., another case?

        case "image"
          if (have_img_data)
            warning ("an axis can only display one image");
          endif
          have_img_data = true;
          img_data = obj.cdata;

Having multiple images shouldn't be too difficult.

However, one thing the file __uiobject_draw_axes__ loses is the order in which 
things are plotted.  Right now it is always image on the bottom, but I'd think 
that the user may not always want that.  Why not retain the order of plotting?  
I'd think it wouldn't be too difficult to build the plot string when going 
through the for loop.
