warmUp property
Whether to compile the scene's render pipelines before revealing it, so the first visible frame does not stall while shaders compile.
When true, the view calls Scene.warmUp with its own views once the loading group (if any) is ready, and reveals only after. This gates the view even without a loading group or loadingBuilder. Populate the scene before warm-up runs (loads tracked by loading are awaited first).
Implementation
final bool warmUp;
