The following data accessors are used only for
SourceDesktop. The corresponding data members were moved to
that class and the accessors ultimately should be as well.
Probably the main obstacle to that move is in ProcessRender's
command parameter substitution. That could be resolved by
providing a more general mechanism for Stream classes to
publish their supported command parameters.
(Many of the accessors in Stream are specific to some child
class; those should be moved out as well for the sake
of clarity.) ---GEC */
