I (for one) still have unanswered questions about the
proposed TIP#171 implementation.  Specifically:

I agree with the TIP#171 Rationale (paraphrased: "On
Windows, mouse wheel scrolling should affect the widget
under the pointer [just like it does on X11 and OSX]
instead of the widget with keyboard focus.")  But the
proposed implementation smells really bad to me.

(The proposed implementation looks like a usable stopgap
solution for Tk <= 8.5, but long-term it is -- I suspect --
something we're just going to have to undo later.)
