Re: Deliver subclasses of appKit classes

Hi Denis,

Yes, that's correct.  To make it more modular, you can keep the symbol on the
plist of some other symbol.

E.g. we do this for a few helper classes in CAPI:

(objc:define-objc-class lw-slider ()
    ()
  (:objc-class-name "LWSlider")
  (:objc-superclass-name "NSSlider"))

(setf (get 'slider-representation 'owner-class) 'lw-slider)

In this case, the code for slider-representation is the only thing that makes
the LWSlider object, so it is the best place to retain it (i.e. only if
slider-representation is retained).
