Xfdesktop now uses Xfconf to store its configuration.  Xfconf is a
hierarchical configuration system.  The channel name that xfdesktop uses
is 'xfce4-desktop'.  Property names below should be referred to with each
component separated by a slash ('/') character.  The data type of each
property is listd after the name.
The monitor settings are referred to by name where possible so that when
the same monitor is plugged in again those settings apply to it.
