I'd prefer an interface where the meaning of a parameter does not depend on 
the value of another. I'd like to be able to change the tolerance and the 
method in separate. Optimally, the user should be able to specify both 
relative and absolute tolerance, and the selected method will use the 
tolerance it supports.

I've created a github issue to work on this, and intend to submit a pull 
request along the lines of my suggestion. Any further comments would be 
welcome.
