+/**
+ * # CategoryLog
+ *
+ * Simple log messages with priorities and categories. A message's
+ * SDL_LogPriority signifies how important the message is. A message's
+ * SDL_LogCategory signifies from what domain it belongs to. Every category
+ * has a minimum priority specified: when a message belongs to that category,
+ * it will only be sent out if it has that minimum priority or higher.
+ *
+ * SDL's own logs are sent below the default priority threshold, so they are
+ * quiet by default.
+ *
+ * You can change the log verbosity programmatically using
+ * SDL_SetLogPriority() or with SDL_SetHint(SDL_HINT_LOGGING, ...), or with
+ * the "SDL_LOGGING" environment variable. This variable is a comma separated
+ * set of category=level tokens that define the default logging levels for SDL
+ * applications.
+ *
+ * The category can be a numeric category, one of "app", "error", "assert",
+ * "system", "audio", "video", "render", "input", "test", or `*` for any
+ * unspecified category.
+ *
+ * The level can be a numeric level, one of "trace", "verbose", "debug",
+ * "info", "warn", "error", "critical", or "quiet" to disable that category.
+ *
+ * You can omit the category if you want to set the logging level for all
+ * categories.
+ *
+ * If this hint isn't set, the default log levels are equivalent to:
+ *
+ * `app=info,assert=warn,test=verbose,*=error`
+ *
+ * Here's where the messages go on different platforms:
+ *
+ * - Windows: debug output stream
+ * - Android: log output
+ * - Others: standard error output (stderr)
+ *
+ * You don't need to have a newline (`\n`) on the end of messages, the
+ * functions will do that for you. For consistent behavior cross-platform, you
+ * shouldn't have any newlines in messages, such as to log multiple lines in
+ * one call; unusual platform-specific behavior can be observed in such usage.
+ * Do one log call per line instead, with no newlines in messages.
+ *
+ * Each log call is atomic, so you won't see log messages cut off one another
+ * when logging from multiple threads.
