* A variable controlling the default SDL log levels.
*
* 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 "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"
