x11: Make selection handling work across screens

Desktop / GNOME / GTK - Matthias Clasen [redhat.com] - 27 July 2015 22:20 UTC

When dealing with selection events, we might see windows from other screens in the requestor field. The current x11 backend code fails to wrap these in a foreign GdkWindow, since we don't have the corresponding GdkScreen anymore. Work around this by creating such 'foreign screens' on demand. We still maintain the 1:1 relation between the display and the screen returned by gdk_display_get_default_screen().
