25 * Simple log messages with categories and priorities.
27 * By default logs are quiet, but if you're debugging SDL you might want:
29 * SDL_LogSetAllPriority(SDL_LOG_PRIORITY_WARN);
31 * Here's where the messages go on different platforms:
32 * Windows: debug output stream
34 * Others: standard error output (stderr)

54 * Messages longer than the maximum size will be truncated

61 * By default the application category is enabled at the INFO level,
