gamma_distribution<> d(1, 1);

No, the second graph, keeps the shape constant and shows the effect of 
varying the scale, while the first image keeps the scale constant and shows 
the effect of varying the shape...

But that means that the two red curves in the two graphs should be the same 
and they're not :-(  Looks like I probably messed up generating the graphs, 
I'll look into this.
