[cairo] Describe the restrictions upon cairo_set_tolerance()
Truc Troung reported that the behaviour of
cairo_set_tolerance()/cairo_get_tolerance() was inconsistent with the
documentation, i.e. we failed to mention that the tolerance would be
restricted to the smalled fixed-point value.
Add a sentence to the documentation that describes the restriction without
mentioning what that is... Hopefully that is sufficient detail to
accommodate the reporter, without exposing internal implementation details.
