pub const DEPTH_ORDER_SPAN: f32 = 1e-4;Expand description
Total normalized-depth span reserved for scene-order biasing.
Fragments whose true depth differs by less than this span may be reordered by scene insertion order (later items on top); anything farther apart keeps true depth ordering. The per-order epsilon divides this span by the frame’s full scene-order span (at least one). This keeps offsets bounded even when omitted render plugins leave gaps in the prepared items’ scene orders.
