According to the RANDR 1.5 spec:
https://cgit.freedesktop.org/xorg/proto/randrproto/tree/randrproto.txt
RRSetMonitor and RRDeleteMonitor requests will generate a
ConfigureNotify event on the root window of the screen.
They do not appear to generate any RRScreenChangeNotify or other
similar event. So this CL causes ScreenCapturerX11's monitor list to be
updated on ConfigureNotify events. It is needed, for example, when
using a commandline such as "xrandr --setmonitor ..." to add monitors.
