Carlos Garnacho 0777cf46d7 xwayland: Improve checks for confined_to on InputOnly windows
In this pretty Wine/Proton specific kludge, we try to handle confining grabs
on InputOnly windows by trying to find the InputOutput window that the pointer
would get visually confined to.

The grabbing window and the visible window come from different clients, so
we used to simply resort to the pointer focus. This is troublesome though, as
the call may happen very soon at a time that the toplevel wasn't yet mapped by
the Wayland compositor, so the pointer focus may well be out of date soon.

In these situations, it does seem that even though the confining grab happens
too early to have the wayland surface mapped, the xserver view of the WindowPtr
does already reflect the size. Use this to find out the better window to
assign the confining grab to, one whose geometry fully contains the InputOnly
window's.

X Server

The X server accepts requests from client applications to create windows, which are (normally rectangular) "virtual screens" that the client program can draw into.

Windows are then composed on the actual screen by the X server (or by a separate composite manager) as directed by the window manager, which usually communicates with the user via graphical controls such as buttons and draggable titlebars and borders.

For a comprehensive overview of X Server and X Window System, consult the following article: https://en.wikipedia.org/wiki/X_server
