Used in simgui_desc_t to provide a logging function. Please be aware
that without logging function, sokol-imgui will be completely
silent, e.g. it will not report errors, warnings and
validation layer messages. For maximum error verbosity,
compile in debug mode (e.g. NDEBUG *not* defined) and install
a logger (for instance the standard logging function from sokol_log.h)
