Sliders are nice when you 

        1. Have a well-defined range,

        2. Don't need much precision.

If you do have a well-defined range *and* you need precision, you can
have a slider next to an entry or spin button.

If you do not have a well-defined range, you should use a plain
entry.  GtkAdjustments and spin buttons work OK if you set the range
of the adjustment to something huge.  You don't want to limit things
like image sizes (except for file format limitations) or brush sizes.
