Motion-independent budget floor: the connector may always reach this multiple of its resting length. Without it the budget collapses to ~rest length when the camera is slow/static, dropping connectors during the normal collision-driven label re-slotting (a transitioning label's frozen previous anchor lags the moving anchor, so the line briefly exceeds rest length). Only genuinely runaway connectors are then suppressed.
Connector-length gate: suppress connector lines that stretch far beyond
what a resting connector plus reasonable per-frame motion (at
connectorTargetFrameTime) would produce. Avoids long, distracting lines
during low fps / fast camera moves.
Optionalset
Explicit background for passes that clear the frame (e.g. RenderPass and the OIT opaque clear). When set, the pass clears to this colour/alpha instead of the renderer's current clear state, giving a single source of truth so the background is identical regardless of which base pass renders the scene. When
nullthe pass falls back to the renderer's current clear colour/alpha.
