I could be wrong, but I think that I can confirm that it is clipped. At least,
when I rewrite my function to assume it is clipped at 1, everything starts
behaving as I expect....
I don't really have any strong feelings either way about clipping on density,
but, if it is clipped, it would be nice if it was clearly documented.
(well, it would stop me trying to write functions like:
density_function = function(x,y,z){min(1,x*x+z*z)})
