+Changing scale factors affect a huge amount of routines in OCE. 
+
+The strategy to reduce the code transformation : 
+- New variables are in dom_oce.F90 and then in dommsk.F90 and domain.F90
+- We use a function that replaces each e3. by its full expression (e3.0*(1+r3.*mask.)) when key_qco is activated, for that we add a specific include of a substitute (domzgr_substitute.h90)
+- When we use to update scale factors with respect to ssh we now update ratios r3. = ssh./h.0. (domqco.F90)
+- We also changed robert asselin filtering routines with optimisation (traatf_qco.F90 and dynatf_qco.F90) and proper specific update of filtered ratios r3.f instead of e3.
+
+This strategy has also been applied to other variables varying with ssh./h.0 such as h. or gde.
+
 When key_qco is not activated NEMO should be produce exactly same results as the trunk and passes SETTE version r13167 has been delivered for mid-merge party !

-When key_qco is activated NEMO passes suitable SETTE tests i.e. custom GYRE_PISCES, ORCA2_ICE_PISCES, SPITZ12, AMM12. ISOMIP cannot run yet nor AGRIF. 
+Changing scale factors also affect external package such as OFF, NST, SWE... that needs to be updates accordingly : 
+
+- update routines of NST
+- revise and clean SWE and transfer improvements for dynldf_lap_blp.F90 and dynvor.F90
+- pressure gradient for ISF TO DO !

 Pseudo merge with NEMO/branches/2020/dev_r12527_Gurvan_ShallowWater consists mainly in modifying dynldf_lap_blp for adding symmetric tensor operator and dynvor for cleaning and diawri for F-point outputs and adding a test case with specific RK3 step.
