 *  Simple log messages with categories and priorities.
 *
 *  By default logs are quiet, but if you're debugging SDL you might want:

 *      SDL_LogSetAllPriority(SDL_LOG_PRIORITY_WARN);
 *
 *  Here's where the messages go on different platforms:
 *      Windows: debug output stream
 *      Android: log output
 *      Others: standard error output (stderr)
