Get horizontal wheel scrolling working again with logitech drivers.
Some Logitech drivers send WM_MOUSEHWHEEL messages to the parent window intermingled with WM_MOUSEWHEEL
messages to the child if there is one. This causes horizontal scrolling to be treated as vertical scroll.
Hack is to remember the last time a WM_MOUSEHWHEEL message is received and treat WM_MOUSEWHEEL messages
which occur in this window as WM_MOUSEHWHEEL messages.
