A new binding code would be better.   I could simplify my code.

+1

So we have consensus there. It would reduce the incompatibility as the original bindings can still be used and new bindings can be introduced to eventually replace them.

As for high-resolution mouse wheels: the new binding code can introduce floating-point numbers. Do we have examples of such mouse wheels? (I am not at all well versed in such matters and seldom use a mouse wheel ;)).

I'd say you don't use a mouse wheel because Windows has had very primitive support for this device, even today.  I've been using a Mac for about 15 years now and just recently starting working on Windows 10.  I find mouse and touch pad behavior on Windows to be horrible at best, whereas on the Mac mouse and touchpad behavior is like an extension of your body.  When I move my fingers and hand, things happen on the screen in a natural fashion.  With Windows, I struggle to find consistent connection between motion and action, often having to revert to the keyboard to get something sane to happen.

But I digress.  I have an Apple Magic Mouse connected to Windows 10, using a beta version of a mouse driver from magicutilities.net<http://magicutilities.net>.  This works fairly well with Windows applications that support Y-axis and X-axis scroll/tilt/gestures.  Only Y-axis scrolling is supported in Tk :(
So this is a good example of a high resolution, multi-function mouse.  I can certainly test these proposed enhancements when available.
