annotate src/video/aalib/SDL_aaevents.c @ 1050:8e1815fd9777
Holding down shift while moving the mouse's scrollwheel on MacOS X makes the
OS report these are "horizontal scrollwheel" events, which confuses gaming
apps in several legitimate conditions. Now all scrollwheel events are made
to look vertical when passed to the app.
Patch by John Knottenbelt.
