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