We can not use the view of that class because with the introduction
of the multi pane GUI we do not switch the SfxViewShell anymore when
switching the view in the center pane. The view id of the
SfxViewFrame is thus not modified and we can not set it from the
outside.
The view id is still needed for the SFX to determine on start up
(e.g. after loading a document) which ViewShellBase sub class to
use. These sub classes--like OutlineViewShellBase--exist only to be
used by the SFX as factories. They only set the initial pane
configuration, nothing more.
So what we do here in essence is to return one of the
ViewShellFactoryIds that can be used to select the factory that
creates the ViewShellBase subclass with the initial pane
configuration that has in the center pane a view shell of the same
type as mrViewShell.
