+C Use [1-d_yy^n)(1-d_xx^n] instead of [1-d_xx^n-d_yy^n]
+C This changes the spectral response function dramatically.
+C You need to do some analysis before changing this option. ;^)
+#define SEQUENTIAL_2D_SHAP

+C Boundary conditions for U,V Shapiro code
+C Horizontal shear is calculated as if the boundaries are no-slip
+#undef  NO_SLIP_SHAP
+
+C This invokes the older code which produces the same numbers
+C and might even be faster because it does not do multiple
+C exchanges within the filter. However, this requires the
+C overlap to be sufficiently wide and also does not work
+C for arbitrarily arranged tiles (ie. as in cubed-sphere).
+C *DO NOT USE THIS OPTION UNLESS YOU REALLY WANT TO*  :-(
