/*                            SOLID PANES
 **
 **     Panes are regions of the outline view in which a particular subject is
 ** displayed in a particular way.
 ** Different panes about the same subject are typically stacked vertically.
 ** Panes may be used naked or with a pane selection header.
 **
 ** The label() method has two functions: it determines whether the pane is
 ** relevant to a given subject, returning null if not.
 ** If it is relevant, then it returns a suitable tooltip for a control which selects the pane
