* The display is represented as a MetaDisplay struct.
*
* \bug Originally we had the idea that there could be multiple MetaDisplay
* structs in one Metacity process, but as the code currently stands, only
* one can be initialised; it is a singleton class. We should go through and
* remove all the code that iterates over the lists of displays later.
* See <http://bugzilla.gnome.org/show_bug.cgi?id=499301>.
