Detailed description of my changes: SDL/configure.in: If Photon detected declare define ENABLE_PHOTON. SDL/src/video/SDL_sysvideo.h: Added extern to ph_bootstrap. SDL/src/video/SDL_video.c: Added ph_bootstrap to bootstrap array. SDL/src/video/photon/SDL_ph_events.c: Declare DISABLE_X11 if compiled for Photon. SDL/src/video/photon/SDL_ph_image.c: Fixed segment violation on exit. Please update BUGS file. SDL/src/video/photon/SDL_ph_video.c: 1. Enabling window manager. 2. Added to device capabilities Photon Window Manager functions: SetCaption and IconifyWindow. 3. Renamed X11_bootstrap to ph_bootstrap. 4. Removed SEGFAULT termination of programs if Photon not available. SDL/src/video/photon/SDL_ph_wm.c: 1. Declare DISABLE_X11 if compiled for Photon. 2. Added ph_SetCaption and ph_IconifyWindow code.

SDL_DisplayFormat\- Convert a surface to the display format
.SH "SYNOPSIS"
.PP
\fB#include "SDL\&.h"
.sp
\fBSDL_Surface *\fBSDL_DisplayFormat\fP\fR(\fBSDL_Surface *surface\fR);
.SH "DESCRIPTION"
.PP
This function takes a surface and copies it to a new surface of the pixel format and colors of the video framebuffer, suitable for fast blitting onto the display surface\&. It calls \fISDL_ConvertSurface\fR
.PP
If you want to take advantage of hardware colorkey or alpha blit acceleration, you should set the colorkey and alpha value before calling this function\&.
.PP
If you want an alpha channel, see \fISDL_DisplayFormatAlpha\fR\&.
.SH "RETURN VALUE"
.PP
If the conversion fails or runs out of memory, it returns \fBNULL\fR
