 :TODO: implement full model with variable exponents.  The current implementation fixes internal
 exponents to 2 and the external exponent to 1/2.
 
+:TODO: add the weights on the quadratic filter
+responses.  E and S are supposed to be the "square root of a *weighted* sum of squares".
+The simplifications here are probably useful, but make them optional, or a different class or something.
+- The current implementation can be interpreted as including the weights inside the filters.
+  The filters are not constrained to have a unit norm, for example.
