Fixed bug #616 rainer canavan 2009-03-29 12:30:12 PDT add default visual to this->hidden->visuals X11_SetIcon appears to have problems getting the correct bpp for the default visual of my screen. With larger icons, this causes a segfault somewhere in libX11. Instead of adding the default visual to the internal list, I can work around this problem (both the segfault and the distortion) by setting bpp to 32 before sicon = SDL_CreateRGBSurface(...) in X11_SetIcon, although with this patch, it stays at 24.
