| No, becaus the idea is that ImageButton will *not* inherit @background
| from Button, it being a separate object.

You want it not to inherit? Do you mean the value of @background or the actual 
method #background? Right now method gets inherited but not the value --you 
can change the value on a per class bases. But if you did not want the method 
inherited... I'm not sure. Guess you could use a module.

Hmm... I wonder how all the variations might be satisfiable... I wonder if 
using something like 'inherit' and 'do_not_inherit', like private and public, 
might not clear all that up. Eg.

  class A
    do_not_inherit
    def self.background
      #...
    end

    inherit
    def repaint
      #...
    end
  end
