 /** @class FilmViewer
  *  @brief A wx widget to view a preview of a Film.
- *
- *  The film takes the following path through the viewer:
- *
- *  1.  get_frame() asks our _player to decode some data.  If it does, process_video()
- *      will be called.
- *
- *  2.  process_video() takes the image from the decoder (_raw_frame) and calls raw_to_display().
- * 
- *  3.  raw_to_display() copies _raw_frame to _display_frame, processing it and scaling it.
- *
- *  4.  calling _panel->Refresh() and _panel->Update() results in paint_panel() being called;
- *      this creates frame_bitmap from _display_frame and blits it to the display.
- *
- * update_from_decoder() asks the player to re-emit its current frame on the next pass(), and then
- * starts from step #1.
- *
- * update_from_raw() starts at step #3, then calls _panel->Refresh and _panel->Update.
