	)			[virtual]

Copies a region of the given frame buffer into this slot.

Parameters:

	fb	a frame buffer.
	x	lower left corner of the area where the pixels must be read.
	y	lower left corner of the area where the pixels must be read.
	w	width of the area where the pixels must be read.
	h	height of the area where the pixels must be read.

virtual void proland::GPUTileStorage::GPUSlot::setSubImage	(	int	x,
		int	y,
		int	w,
		int	h,
		TextureFormat	f,
		PixelType	t,
