I don't think that's quite what Hugo was looking for.  I've run in to
his problem myself, particularly with the game Maelstrom.  Maelstrom
runs at 640x480.  Maximizing the window doesn't change that, you merely
get a full-screen black window with a little 640x480 section in the
center in which the game is displayed.  The only way to have the actual
game take up the full screen is to change the display resolution to
640x480 and move the mouse around until the Maelstrom window is the only
portion of the larger "virtual desktop" that can be seen.

I don't think there's a better way to do this, as Hugo suspected.  If
you could easily move the mouse using script commands, you could
probably write something to parse the output of xwininfo and move the
mouse to a corner of a given window.  But this doesn't help the problem
of accidentally moving the mouse outside the window, causing the window
to go flying off your screen as you scroll around your virtual desktop.
