Image resize.

Apparently I missed a message here: I didn't get the one with the full  
code.

If anyone knows how to get the original size of an image, we could  
simply handle the resizeControl method and check to see if a key is  
being held down down (maybe controlKey or shiftKey) and adjust the  
height/width accordingly.

Something like this:

on resizeControl
   if the first word of the abbreviated name of the target is "image"  
and the shiftKey is down then
     put the height of the target into curhigh
     put the width of the target into curwide
     put the <original height> of the target into orighigh
     put the <original width> of the target into origwide

     put origwide/orighigh into aspect1
     put orighigh/origwide into aspect2

     multiply aspect1 by curhigh
     multiply aspect2 by curwide

     if aspect1 > curwide then
       set the height of the target to aspect2
     else if aspect2 > curhigh then
       set the width of the target to aspect1
     end if
   end if
end resizeControl

Obviously, we could simply record the original width/height before  
resizing, and this could be used to maintain the aspect "as is" during  
the resize, but I would personally prefer to maintain the original  
aspect ratio recorded in the image file.  Is it possible to get that  
info from rev (the actual pixel width and height recorded in an image)?
