[ale] displays

[Marc Vogt]

All this display stuff reminded me of a question that I've had for
a while.  When you export a display as described previously, 
sometimes the application is too big for the way you have your screen
set up (640x480 with 800x600 for my little laptop).  How can you 
change the size of the application exteriorly ( that is without
configuring the ap itself)?  Can you just use something like
'swallow'?  Any tips appreciated.

thanks

Marc
