[PATCH] gitk: Handle MouseWheel events on Windows
Windows, unlike X-Windows, sends mousewheel events by default to the window that has keyboard focus and uses the MouseWheel event to do so. The window to be scrolled must be able to take focus, but gitk's panels are disabled so cannot take focus. For all these reasons, a different design is needed to use the mousewheel on Windows. The approach here is to bind the mousewheel events to the top level window and redirect them based upon the current mouse position.
