Protocol to be observed by all style delegate objects.  These objects handle the drawing responsibilities for PSMTabBarCell; once the control has been assigned a style, the background and cells draw consistent with that style.  Design pattern and implementation by David Smith, Seth Willits, and Chris Forsythe, all touch up and errors by John P. :-)
