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

.SH "DESCRIPTION"
.PP
\fBSDL_UserEvent\fR is in the \fBuser\fR member of the structure \fI\fBSDL_Event\fR\fR\&. This event is unique, it is never created by SDL but only by the user\&. The event can be pushed onto the event queue using \fI\fBSDL_PushEvent\fP\fR\&. The contents of the structure members or completely up to the programmer, the only requirement is that \fBtype\fR is a value from \fBSDL_USEREVENT\fP to \fBSDL_NUMEVENTS-1\fP (inclusive)\&.
