logGetDebugEnabled

Return whether debug output from the GLib logging system is enabled.

Note that this should not be used to conditionalise calls to funcGLib.debug or other logging functions; it should only be used from [glib.types.LogWriterFunc] implementations.

Note also that the value of this does not depend on G_MESSAGES_DEBUG, nor funcGLib.log_writer_default_set_debug_domains; see the docs for funcGLib.log_set_debug_enabled.
