This patch is based on the patch in bug#64425 (since I noticed this
unrelated issue while working on that, and they touch the same code).



When pixel-scroll-precision-mode is enabled, scrolling the mouse wheel
will yield wheel-{up,down} events.  flymake now binds the new events
in addition to the old mouse-wheel-{up,down}-event.

* lisp/progmodes/flymake.el:(flymake--mode-line-counter-scroll-prev,
flymake--mode-line-counter-scroll-next,
flymake--mode-line-counter-map): Add.
(flymake--mode-line-counter): Use new keymap and include 'type as a
property in the mode-line.
