spawn_sync()

void MayaFlux::Portal::Forma::Bridge::spawn_sync	(	Layer &	layer,
		uint32_t	id,
		std::function< void()>	sync_fn
	)

Spawn a presentation sync task scoped to a Layer.

The task name is also stored in the outbound_tasks of the record for id, when one exists, so that unbind() cancels it. layer must be owned by a shared_ptr.

Parameters

layer	Layer that owns the task.
id	Element id used for task naming and diagnostics.
sync_fn	Function invoked once per graphics frame.
