Fixed bug #220 The AltiVec blitters don't compile, since they require __VEC__ to be enabled in order for the compiler to understand "vector" and friends (i.e. do AltiVec) But you don't want to turn AltiVec on globally, since then the code would only run on a G4 (there are already runtime tests, before using the AltiVec variants) The solution here is to enable AltiVec locally, for the actual AltiVec code.

\fBSDL_APPMOUSEFOCUS\fP if mouse focus was gained or lost, \fBSDL_APPINPUTFOCUS\fP if input focus was gained or lost, or \fBSDL_APPACTIVE\fP if the application was iconified (\fBgain\fR=0) or restored(\fBgain\fR=1)\&.
.SH "DESCRIPTION"
.PP
\fBSDL_ActiveEvent\fR is a member of the \fI\fBSDL_Event\fR\fR union and is used when an event of type \fBSDL_ACTIVEEVENT\fP is reported\&.
.PP
When the mouse leaves or enters the window area a \fBSDL_APPMOUSEFOCUS\fP type activation event occurs, if the mouse entered the window then \fBgain\fR will be 1, otherwise \fBgain\fR will be 0\&. A \fBSDL_APPINPUTFOCUS\fP type activation event occurs when the application loses or gains keyboard focus\&. This usually occurs when another application is made active\&. Finally, a \fBSDL_APPACTIVE\fP type event occurs when the application is either minimised/iconified (\fBgain\fR=0) or restored\&.
.PP
.RS
\fBNote:  
.PP
This event does not occur when an application window is first created\&.
