It's neither a bug nor a difference. You have to specify a correct
max_gradient value like it is mentioned in the docs (section 3.4.4.7 and
6.5.4.5.3).
If you are trying to render the functions in the 3.5 docs, make sure you
add a higher max_gradient than default for the later functions (it's also
mentioned in the text).
