logGetDebugEnabled
Return whether debug output from the GLib logging system is enabled.
Note that this should not be used to conditionalise calls to g_debug() or other logging functions; it should only be used from %GLogWriterFunc implementations.
Note also that the value of this does not depend on G_MESSAGES_DEBUG
; see the docs for g_log_set_debug_enabled().
Return
true if debug output is enabled, false otherwise
