template<class srcT , class destT >

void vil3d_grad_3x3x3	(	const vil3d_image_view< srcT > &	src_im,
		vil3d_image_view< destT > &	grad_i,
		vil3d_image_view< destT > &	grad_j,
		vil3d_image_view< destT > &	grad_k
	)

Compute gradients using 3D version of sobel operator.

Resulting images have same size as src_im. Border pixels set to zero. Smooths in two directions with 1-2-1 filters, then applies (-0.5 0 0.5) filter along the third. Intermediate images of type destT
