Adam Strzelecki to SDL Since current DirectFB implementation is incomplete for YUV surfaces (actually causes segmentation faults when trying Lock and use YUV planar textures) I decided to fix it a bit. Here's a patch that should make DirectFB properly support YUV both packed and planar (3 planes). (1) Removed SDL_BYTESPERPIXEL at all in favor of DFB_BYTES_PER_PIXEL(SDLToDFBPixelFormat(fmt)) which does return always proper BPP for YUVs too, coz SDL_BYTESPERPIXEL returns incorrect values for FOURCCs (2) Fixed data->pixels allocation for planar YUVs in CreateTexture, it should allocate 150% more space (3) Copy other planes for planar YUVs in UpdateTexture (4) Moved checking if format is supported at all with DirectFB on CreateTexture at the beginning of the code Waiting for comments, -- Adam Strzelecki | nanoant.com

.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)\&.
