\& Title   : render
\& Usage   : ( $rendered, $panel ) =
\&               $renderer\->render( $collection, $configurator [, $panel ] );
\& Function: Renders the SeqFeatures in the given collection onto a
\&           Bio::Graphics::Panel (if no panel is given, one will be
\&           created), using the given Bio::Graphics::ConfiguratorI for general
\&           and track\-specific rendering options.
\& Returns : In a scalar context returns the number of tracks rendered.
\&           In a list context, returns a two\-element list containing
\&           the number of features rendered and the panel.
\& Args    : A Bio::SeqFeature::CollectionI and a Bio::Graphics::ConfiguratorI
\&           and optionally a Bio::Graphics::Panel.
\& Status  : Public
