[PATCH v2 5/6] spice: get monitors physical dimension

[marcandre.lureau@xxxxxxxxxx]

From: Marc-André Lureau <marcandre.lureau@xxxxxxxxxx>

Note that for consistency, we use the same logic as MonitorsConfig to
figure out the associated monitor. However, I can't find traces of the
discussion/patches about the "new spice-server" behaviour: it still uses
the multiple-configurations path in git master.
