command: check for monitor par in window-scale 

When performing the scaling calculations, the window scale properties do
not bother checking for potential monitor par. The vo keeps track of
this via vo->monitor_par. Simply multiply/divide the video's width or
height depending on the value of monitor_par. We also clamp the values
to avoid the values running away to infinity in extreme cases.
