Actually, now that I look closely, I see there _aren't_ any such demos 
in image.dem.  (I will add such an example.)  I know this works in the X 
term driver.  But I don't think any of us thought to check this out in 
all the terminals (i.e., PostScript, PDF, PNG, etc.).  In fact, OK, I 
just checked a range clipped image example using the PNG terminal 
driver.  It fails.  There are two sets of coordinates sent through the 
terminal image call, the location of the image and the visible area.  
(For systems that can display portions of pixels on the edge.)

I'll go through the terminals one at a time and let you know when they 
are ready.

Thanks for find this,

Dan
