- AppHandler::render now receives the current &Frame; its default
implementation renders the whole scene automatically via
app.render_scene(frame.view()) (Option A). Users can simply not
implement render for full auto-rendering.
- Add Renderer::render_scene: batch-renders every scene entity in a
single render pass. Factored per-mesh draw logic into a private
draw_entity helper shared with Renderer::render.
- Add App::render_scene(view) delegating to the Renderer.
- Fill simple.rs with a real quad (mesh/material/entity) without
importing wgpu; the scene now auto-renders via the trait default.
- Wrap in backticks every bare type in rustdoc comments (vertex.rs,
frame.rs, pipeline_cache.rs, material.rs, mesh.rs, scene.rs, error.rs)
so rustdoc no longer misreads them as intra-doc links or HTML tags.
- Add a missing doc comment on the public Frame struct.
- Add #![warn(missing_docs)] to the crate root so unevidenced public
items are surfaced going forward.
cargo doc --no-deps now generates with zero warnings.
