* Notes:
* "Active" means different things in Mac and Tk terminology --
* On Aqua, widgets are "Active" if they belong to the foreground window,
* "Inactive" if they are in a background window.
* Tk uses the term "active" to mean that the mouse cursor
* is over a widget; aka "hover", "prelight", or "hot-tracked".
* Aqua doesn't use this kind of feedback.
*
* The QuickDraw/Carbon coordinate system is relative to the
* top-level window, not to the Tk_Window. BoxToRect()
* accounts for this.
