/* this function needs 4 parameters:
**
**Function:	PlanarToChunky()
**
**short:		Converts a planar picture data to chunky data.
**
**Inputs:
**	chunky_byte:	is a pointer to a clear allocated public memory that
**			it's size is (ImageByteSize * Depth) bytes.
**
**	*Planes:	is an array of pointers to the BitPlane, normally
**			it is a Planes[] in BitMap structure.
**
**	ImageByteSize:	is the size of each plane in bytes. It can be
**			calculated using (BytesPerRow * Height) both
**			from BitMap structure.
**
**	Depth:		is Depth of planar image, normally the Depth
**			in the BitMap structure.  It supports up to 8
**			bits depth images.
**
**Results:
**	A pointer to the converted chunky image or FALSE (0) for error.
**
**See Also:
**	ReadPixelArray8(), ReadPixel#?(), ReadChunkyPixel#?()
**
**Bugs:
**	Not tested for bugs yet.
