void vil_compute_offsets	(	vcl_vector< vcl_ptrdiff_t > &	offset,
		const vil_structuring_element &	element,
		vcl_ptrdiff_t	istep,
		vcl_ptrdiff_t	jstep
	)

Generate a list of offsets for use on image with istep,jstep.

Gives an efficient way of looping through all the pixels in the structuring element
