Exporting a rect grabs the specified portion of the screen buffer, which 
will also include anything an external blitted to the window but of 
course is limited to the screen bounds.

Exporting an object will cause the object (and if it's a group or a card 
any interior objects) to be rendered into a new buffer, which will work 
regardless of where the source object is located (even off screen), but 
what an external may paint over the card isn't an object per se so LC's 
rendering engine has no way to create that when it generates into its 
buffer.

If the external could be modified to use an image object as its output 
you'd have all sorts of flexibility for handling it.
