// Each Prefs object needs the following methods:
// prefsObj.create (parentPane) - create the pane and return the Pane object.
// pane.preProcess()			- preprocess the pane just before being shown.
// pane.layoutDone()			- informs the pane that the initial layout is done (optional)
// pane.postProcess()			- do any work just before the pane is being hidden.
// pane.store()					- store the preferences. Return true if the Next Time dialog is needed.
// pane.toDefault()				- set back to default values
// pane.cancelled()				- Prefs dialog has been cancelled

// On Windows, the "Cmd" modifier is mapped to the Ctrl modifier, so Ctrl-X combos end up as
// Cmd-X combos on the Mac.
