Functions
void	STDWTITL_clearVram (void)
	Resets the GPU and clears the whole VRAM to black, around the movies.
void	STDWTITL_initDecEnv (DecEnv *dec, s16 x0, s16 y0, s16 x1, s16 y1)
	Sets up the movie decoder: its VLC and slice buffers, and the two places in VRAM (x0, y0 and x1, y1) its frames alternate between.
void	STDWTITL_readStream (CdlLOC *loc)
	Seeks the CD to loc and starts streaming the movie from there, retrying until it works.
void	STDWTITL_initStream (CdlLOC *loc, void(*callback)())
	Resets the MDEC, has callback run for each decoded slice, sets up the ring buffer and starts streaming the movie from loc.
u_long *	STDWTITL_getNextFrame (DecEnv *dec)
	Waits for the next movie frame in the ring buffer and returns it (NULL if none came); flags the movie's end at its last frame and clears VRAM when the size changes.
s32	STDWTITL_decodeNextFrame (DecEnv *dec)
	Takes the next movie frame and decodes its VLC data into the other VLC buffer; -1 if no frame came, 0 otherwise.
void	STDWTITL_onSliceDecoded (void)
	Called by the MDEC for each decoded slice of a movie frame: copies it to VRAM and decodes the next one, or marks the frame done and switches to the other buffer.
void	STDWTITL_waitFrameDecoded (DecEnv *dec, s32 mode)
	Waits until the MDEC has decoded the whole frame (switching buffers itself if it takes far too long); mode is not used.
void	STDWTITL_tickMoviePlayer (MoviePlayerTask *task)
	The movie player's task: allocates its buffers and starts the movie, then shows a frame each update until the movie's last frame or Start; when killed, stops the CD, frees the buffers and clears VRAM.
MoviePlayerTask *	STDWTITL_startMoviePlayerTask (s32 file, u32 endFrame)
	Creates the movie player (task) for the movie in file, which ends on frame endFrame.
void	STDWTITL_tickMovie (MovieTask *task, MoviePlayerTask **player)
	A movie's task: picks the movie's file and next mode (the European version's last movie by the language), plays it, then reloads the font and goes on to that mode.
MovieTask *	STDWTITL_startMovieTask (s32 movie)
	Creates the task that plays STDWTITL_movies[movie].
