Function render_scene_once 

pub fn render_scene_once(
    scene: &Scene,
    setup: &RenderSetup,
    output: &Output,
    buffer_count: usize,
)

Available on crate feature cmd-render and non-target_family=wasm only.

Render a single ad-hoc output for a scene.

This is the low-level rendering entry point used by ranim render: it renders the whole scene once with the given Output, but unlike render_scene_output_with_progress it does not process capture marks.
