Gtk::Scale.set_draw_value(0) resets the scale's step

[Rafał Cieślak]

Calling set_draw_value(0) when a scale has a step set (either in a constructor, or using a set_digits() method) resets the step.

Steps to reproduce:

Create, lets say, a HScale and set it's step to one.
Then hide it's value.
        Gtk::HScale* scale = new Gtk::HScale(0,5,1);
        scale->set_draw_value(0);

Or, alternatively
        Gtk::HScale* scale = new Gtk::HScale;
        scale->set_digits(0);
        scale->set_draw_value(0);

What is expected:
  A horizontal scale, without it's value drawn, which user can set only to integer numbers (since the step is 1).

What happens instead:
  A scale in fact doesn't have it's value drawn, but the user can move it smoothly, continuously, the step is surely much smaller than 1.
