    Implement Generator::ensure_started().
    
    One of the calls to iterate_spigot_algorithm in BracketingGenerator
    existed solely for its side effect of initialising the underlying
    core, which is necessary before attempting to premultiply anything
    into it. That's pretty ugly, so I've moved out the mandatory init code
    into a separate ensure_started() method and replaced the iterate call
    in question with that.

    Turn get_true_approximant() into get_floor().
    
    It was only ever used with a denominator of 1, so I've removed the
    denominator argument and simplified it right down.

    Replace 'outmatrix' with a scalar multiplier.
    
    In all the places where a non-NULL outmatrix was used, it was only
    ever used to multiply by a scalar. And multiplying by a scalar is much
    more easily achieved _after_ core->endpoints() returns, rather than
    having to plumb an entire spare matrix through to the endpoint
    calculations.
