From Bug #36: There are a couple of issues with the selection of Altivec alpha-blitting routines in CalculateAlphaBlit() in src/video/SDL_Blit_A.c. 1) There's no check for the presence of Altivec when checking if the Blit32to565PixelAlphaAltivec() routine can be selected. 2) Altivec cannot be used in video memory, and there's no check if the destination surface is a hardware surface. (Alpha-blitting to a hardware surface with GPU support is a bad idea, but somebody's bound to do it anyway.) Patch to fix these attached.

.SH "DESCRIPTION"
.PP
\fBSDL_KeyboardEvent\fR is a member of the \fI\fBSDL_Event\fR\fR union and is used when an event of type \fBSDL_KEYDOWN\fP or \fBSDL_KEYUP\fP is reported\&.
.PP
The \fBtype\fR and \fBstate\fR actually report the same information, they just use different values to do it! A keyboard event occurs when a key is released (\fBtype\fR=\fBSDK_KEYUP\fP or \fBstate\fR=\fBSDL_RELEASED\fP) and when a key is pressed (\fBtype\fR=\fBSDL_KEYDOWN\fP or \fBstate\fR=\fBSDL_PRESSED\fP)\&. The information on what key was pressed or released is in the \fI\fBkeysym\fR\fR structure\&.
.PP
.RS
\fBNote:  
.PP
Repeating \fBSDL_KEYDOWN\fP events will occur if key repeat is enabled (see \fI\fBSDL_EnableKeyRepeat\fP\fR)\&.
