The System 7 CDEF appears to use the window's :content color instead of the control's
:body color as the background color when drawing check boxes and radio buttons. This is,
I believe, different than System 6's behavior, though I didn't check that today.
In order to make it look right, I found it necessary to both:
(set-back-color <window> <color>)
(set-part-color <window> :content <color>)
For system 6, you may also need:
(set-part-color <radio button or check box> :body <color>)
