#     HID: input: simplify/fix high-res scroll event handling
#     
#     Commit 1ff2e1a44e02 ("HID: input: Create a utility class for counting
#     scroll events") created the helper function
#     
#         hid_scroll_counter_handle_scroll()
#     
#     to handle high-res scroll events and also expose them as regular wheel
#     events.
#     
#     But the resulting algorithm was unstable, and causes scrolling to be
#     very unreliable.  When you hit the half-way mark of the highres
#     multiplier, small highres movements will incorrectly translate into big
#     traditional wheel movements, causing odd jitters.
#     
#     Simplify the code and make the output stable.
#     
#     NOTE! I'm pretty sure this will need further tweaking.  But this at
#     least turns a unusable mouse wheel on my Logitech MX Anywhere 2S into
#     a usable one.
