     ==============================
 
+o PTRACERS: added namelist parameter PTRACERS_ref in analogy to tRef
+  and sRef for convenience, handy, when you want to initialize
+  ptracers in a large domain with a constant non-zero value. Also,
+  untangle ptracers_init.F a little.

 o vorticity & strain are now computed without masking, to account for 
   no-slip-side BC in variable viscosity calculation ; mask is applied
   anyway later on, before computing advection/coriolis terms.
