frame_results() [1/2]

void MayaFlux::Kriya::frame_results	(	Vruta::TaskScheduler &	scheduler,

Signal what fn returns into source once per graphics frame.

As the overload that creates its source, for a source that already has a consumer, so fn can refer to that consumer. The routine holds source weakly.
