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. (Thanks to 'phearbear' for iconify window source). 3. Some stubers for other wm functions. Thanks ! ---------------------------- Mike Gorchak CJSC Malva System Programmer
