wine's fullscreen code has no effect on metacity

Windows does not have a fullscreen mode. In Windows, windows that are
Always on Top are on top of panels. Windows applications enter
"fullscreen mode" by positioning themselves take up the whole screen
and being always on top (actually, now I'm not so sure they have to be
always on top; I'm only basing that on my experience as a Windows
user).

When the size of a window or the screen resolution changes, Wine marks
windows whose client area covers the whole screen as fullscreen. This
is done in the update_fullscreen_state function in this file:

Yep.

That issue is with Alt+F11 (metacity forcing fullscreen mode), and
it's not really as important, since Windows can't do anything like
that.

I'll look at that when I have a chance (even though I'm not really an
expert on this stuff), thanks.
