 Summary of the bug: Toggling the `ffplay` 'maximize' function (e.g., by
 typing 'f' twice) does not restore the window to its original position;
 the restored position is offset by (dx, dy), where dx and dy are the width
 and height of the window decorations.

 Add'l info:

   * System: Arch linux, kernel 6.1.68

   * Window manager: fvwm3.

   * Issue does not occur if the window has no decorations,
     presumably because in this case dx = dy = 0.

   * `mpv` does not exhibit this behavior, leading me to believe that
     the problem is more likely `ffplay/ffmpeg` rather than my window
     manager.



 How to reproduce:

 {{{
 $ ffplay -left 0 -top 0 some_video.mp4   # Place window northwest corner
 at (0,0)
 }}}

 Now type 'f' twice to maximize/restore the window position. What I observe
 is that the restored window position is now at (dx,dy), rather than at
 (0,0) where it began. Hit "f" two more times, and the restored position is
 now at (2*dx, 2*dy), etc.
