C You need to do some analysis before changing this option. ;^) #define SEQUENTIAL_2D_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).
