timeoutSourceNew
Creates a new timeout source.
The source will not initially be associated with any struct@GLib.MainContext and must be added to one with method@GLib.Source.attach before it will be executed.
The interval given is in terms of monotonic time, not wall clock time. See func@GLib.get_monotonic_time.
Return
the newly-created timeout source
Parameters
interval
the timeout interval in milliseconds.
