pub fn default_options() -> LitOptionsExpand description
Default options for the ported ECS scenes: per-instance transform and tint, no texture, no MSAA, with reverse-z depth.
The options are pure policy, so they say nothing about the geometry a draw carries: which vertex channels a mesh packs follows the slices its caller uploads, and which of them a draw reads follows the mesh it draws. The tint rides the same per-instance record as the transform, so a draw that reads instances reads the tint too.
