	56	!! * ROUTINE tra_ldf_iso_grif *
	57	!!
[3294]	58	!! ** Purpose : Compute the before horizontal tracer (t & s) diffusive
	59	!! trend for a laplacian tensor (ezxcept the dz[ dz[.] ] term) and
[2450]	60	!! add it to the general trend of tracer equation.
	61	!!
[3294]	62	!! ** Method : The horizontal component of the lateral diffusive trends
[2450]	63	!! is provided by a 2nd order operator rotated along neural or geopo-
	64	!! tential surfaces to which an eddy induced advection can be added
	65	!! It is computed using before fields (forward in time) and isopyc-
	66	!! nal or geopotential slopes computed in routine ldfslp.
	67	!!
	68	!! 1st part : masked horizontal derivative of T ( di[ t ] )
	69	!! ======== with partial cell update if ln_zps=T.
	70	!!
	71	!! 2nd part : horizontal fluxes of the lateral mixing operator
[3294]	72	!! ========
[2450]	73	!! zftu = (aht+ahtb0) e2u*e3u/e1u di[ tb ]
	74	!! - aht e2u*uslp dk[ mi(mk(tb)) ]
	75	!! zftv = (aht+ahtb0) e1v*e3v/e2v dj[ tb ]
	76	!! - aht e2u*vslp dk[ mj(mk(tb)) ]
	77	!! take the horizontal divergence of the fluxes:
	78	!! difft = 1/(e1te2te3t) { di-1[ zftu ] + dj-1[ zftv ] }
	79	!! Add this trend to the general trend (ta,sa):
	80	!! ta = ta + difft
	81	!!
	82	!! 3rd part: vertical trends of the lateral mixing operator
	83	!! ======== (excluding the vertical flux proportional to dk[t] )
	84	!! vertical fluxes associated with the rotated lateral mixing:
	85	!! zftw =-aht { e2t*wslpi di[ mi(mk(tb)) ]
	86	!! + e1t*wslpj dj[ mj(mk(tb)) ] }
	87	!! take the horizontal divergence of the fluxes:
	88	!! difft = 1/(e1te2te3t) dk[ zftw ]
	89	!! Add this trend to the general trend (ta,sa):
	90	!! pta = pta + difft
	91	!!
