WMs each have their little quirks with that. When you change the
size hints, they get a ConfigureNotify event with the
WM_NORMAL_SIZE_HINTS Atom. They all save the hints then, but they
don't all resize the window right away to enforce the new hints.
Some of them resize only after:
- A user-initiated move or resize
- A code-initiated move or resize
- Hiding & showing window (Unmap & map)
The following move & resize seems to help a lot of WMs that didn't
properly update after the hints were changed. We don't do a
hide/show, because there are supposedly subtle problems with doing so
and transitioning from windowed to fullscreen in Unity.
