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. http://www.libsdl.org/pipermail/sdl/2005-March/067978.html
