Subject: SDL: Don't pass null pointers to
 SDL_DestroyTexture/SDL_DestroyRenderer

SDL does not like this and will raise an assertion when built with
internal SDL assertions turned on. With internal assertions turned
off, it will still call SDL_SetError any time a null pointer is
passed, though it will not raise an assertion or crash.
