GSL and R doesn't use the location parameter then. And Numpy's Gamma PDF

I am guessing that everyone has its own style when it comes to represent the
distributions. Not so surprisingly it is shown in a different form in my
Cloud and Precipitation Parametrization book.
I suggest to add a statement like: Gamma distribution is mainly used to
represent precipitation distribution in bulk cloud parametrization schemes.
