The SelectionOnly property from the export file dialog was not passed down from
GraphicExportFilter::filter() to DocumentToGraphicRenderer so that always
passed a component model instead of a selection object to the implementation of
XRenderable (getRendererCount(), getRenderer(), render())
Also have GraphicExportDialog consider the selection so the
DocumentToGraphicRenderer at its GraphicExportOptionsDialog calls XRenderable
the same.
