From: Niklas Haas <g...@haasn.dev>
In particular, allows users to go all the way up to PL_LOG_TRACE if
desired. (While also avoiding some potentially unnecessary callbacks for
filtered messages, including e.g. the CPU cost of printing out shader
sources)
Response to runtime log level changes by updating it once per
filter_frame(), which should hopefully be often enough.
