requestVisualUpdate abstract method

void requestVisualUpdate()

Called by a PipelineOwner connected to this PipelineManifold when a RenderObject associated with that pipeline owner wishes to update its visual appearance.

Typical implementations of this function will schedule a task to flush the various stages of the pipeline. This function might be called multiple times in quick succession. Implementations should take care to discard duplicate calls quickly.

A PipelineOwner connected to this PipelineManifold will call PipelineOwner.onNeedVisualUpdate instead of this method if it has been configured with a non-null PipelineOwner.onNeedVisualUpdate callback.
