It seems that the current W32 code already does some kind of "window
manager emulation" with respect to the window size ("Force width and
height of client area to be exact multiples of the character cell
dimensions.") in response to WM_WINDOWPOSCHANGING.  I have no
experience of W32 programming, but I guess adding some code that
restricts width/height to the available area to this part would work.
