Fixed bug 3992 - SDL_GetColorKey doesn't set error message Luke A. Guest SDL_GetColorKey does not set an error message on failure. The current source just returns -1. The documentation https://wiki.libsdl.org/SDL_GetColorKey?highlight=%28%5CbCategoryAPI%5Cb%29%7C%28SDLFunctionTemplate%29 says to call SDL_GetError but that is useless in this case.
