A PlaybackTransportRowPresenter renders a PlaybackControlsRow to display a series of playback control buttons. Typically this row will be the first row in a fragment such as the PlaybackSupportFragment.

The detailed description is rendered using a Presenter passed in setDescriptionPresenter(Presenter). This can be an instance of AbstractDetailsDescriptionPresenter. The application can access the detailed description ViewHolder from PlaybackTransportRowPresenter.ViewHolder.getDescriptionViewHolder().
