Expands deep sample thickness by pulling deep.front forward and pushing deep.back back by a shared expand amount.
Deep Expander adjusts deep data so each sample covers a wider depth range. It subtracts the expand value from deep.front and adds the same value to deep.back via a DeepExpression.
Use it when deep holds are too thin for the holdout or merge you need, or when you want a simple, uniform depth pad before further deep ops. Feed a deep stream in; the gizmo outputs deep with the same channels, only front/back shifted.
The expand control is exposed on the group (range 0–100). Larger values thicken samples more; it does not resample, filter, or change deep.Z beyond front/back expansion.
