 | static | 
Gets the singleton Gdk::DisplayManager object. 
When called for the first time, this function consults the GDK_BACKEND environment variable to find out which of the supported GDK backends to use (in case GDK has been compiled with multiple backends).
Applications can use set_allowed_backends() to limit what backends will be used.
