I do not know why I have used "g_source_destroy()", perhaps seeing some
example somewhere on the internet.

What is the difference between "g_source_destroy()" and
"g_source_remove()"? Can I safely use "g_source_remove()" without
breaking something else? Or do I even have to use "g_source_remove()"
because the other is missing to do something important?
