Functions
void	FIELDSTG_touchStream (StreamTask *task)
	Marks a stream task used now (FIELDSTG_findOldestStream)
void	FIELDSTG_seekStream (StreamTask *task, s32 frame, s32 size)
	Reads a frame of the map file, a tile, from the CD, unless it has it already.
s32	FIELDSTG_isStreamLoaded (StreamTask *task)
	Whether a stream task's read is done.
void	FIELDSTG_drawStream (StreamTask *task, Layer *layer, s32 x, s32 y)
