fn options_for(topology: PrimitiveTopology) -> LitOptionsExpand description
The options one topology draws with.
The topology is part of the options, so it is part of the pipeline key: a family variant is compiled per topology, which is why an entity cannot share a key with a different one.
Culling is off, unlike the other scenes. What this scene pins is the primitive each pipeline assembles, and culling would hide half of it: a strip alternates the winding of the triangles it composes, so a back-face test would drop every other one and the snapshot could no longer show the topology whole. Pinning culling is the opaque scenes’ job.
