Olivier Fourdan 246ae00ba3 xwayland: Notify of root size change with XRandR emulation 
Some clients (typically Java, but maybe others) rely on ConfigureNotify
or RRScreenChangeNotify events to tell that the XRandR request is
successful.

When emulated XRandR is used in Xwayland, compute the emulated root size
and send the expected ConfigureNotify and RRScreenChangeNotify events
with the emulated size of the root window to the asking X11 client.

Note that the root window size does not actually change, as XRandR
emulation is achieved by scaling the client window using viewports in
Wayland, so this event is sort of misleading.

Also, because Xwayland is using viewports, emulating XRandR does not
reconfigure the outputs location, meaning that the actual size of the
root window which encompasses all the outputs together may not change
in a multi-monitor setup. To work around this limitation, when using an
emulated mode, we report the size of that emulated mode alone as the
root size for the configure notify event.

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

All questions regarding this software should be directed at the Xorg mailing list:
