/**
* MetaMonitorManager:
*
* A manager for multiple monitors
*
* #MetaMonitorManager is an abstract class which contains methods to handle
* multiple monitors (both #MetaMonitor and #MetaLogicalMonitor) and GPU's
* (#MetaGpu). Its functions include reading and/or changing the current
* configuration and available capabiliies.
*
* The #MetaMonitorManager also provides the "org.gnome.Mutter.DisplayConfig"
* DBus service, so apps like GNOME Settings can use this functionality.
