public void prop_widget_set_factor (Widget widget, double factor, double step_increment, double page_increment, int digits)
Change the display factor of the property widget relatively to the property it was bound to.
Currently the only types of widget accepted as input are those created by prop_spin_scale_new and prop_spin_button_new.
If factor is 1.0, then the config property and the widget display map exactly.
If factor is not 1.0, the widget's range will be computed based of property_name's range multiplied by
factor. A typical usage would be to display a [0.0, 1.0] range as [0.0, 100.0] by setting 100.0 as factor. This
function can only be used with double properties.
The step_increment and page_increment can be set to new increments you want to get for this new range. If you
set them to 0.0 or negative values, new increments will be computed based on the new factor and previous factor.
