Function Documentation

void display	(	BOOL	rebuild,
		F32	zoom_factor,
		int	subfield,
		BOOL	for_snapshot
	)

We copy the frame buffer straight into a texture here, and then display it again with compositor effects. Using render to texture would be faster/better, but I don't have a grasp of their full display stack just yet.
