Hello,

It happens that I needed a similar solution. I didn't have much time and am 
not an expert in mpl, but I've created a rough hack from density.hpp that 
seems to work...
And I think that this is a very useful feature, because otherwise I would 
have to do the hack with setting the cache to 2 and injecting 2 dummy 
samples with the bounds...

Sending again, as during the night I sent from the wrong address and got a bounce.
