libcommon.la defines several new GTypes, so it cannot be loaded into the
same process multiple times.
Copy gconf-property-editor to libgnome-control-center as this is useful
for all panels. However, it will need to be converted to GSettings in the
near future.
Copy capplet-stock-icons to the mouse panel, as it is not used in any other
panels.
Remove references to functions not yet implemented for panels (help,
window icon, etc).
CcShell is an abstract class that represents an instance of a control
center shell. It provides access to some of the properties of the shell
that panels will need to read or change. When a panel is created it has an
instance of CcShell available that represents the current shell.
CcPanel is an abstract class used to implement panels for the shell. A
panel contains a collection of related settings that are displayed within
the shell window.
