Execute a retained Scene3D scene with WebGL
Lower exact retained 3D geometry to a versioned browser-safe GPU plan.
Executable WebGL Scene3D plans
Load the retained 3D scene model and its WebGL host renderer.
Create a pickable scene and inspect the versioned plan.
The result content is rix.webgl-plan@1 JSON. A browser host passes that plan to paintWebGLPlan; the return value includes projected annotation overlays and the picking table keyed by the retained Scene3D IDs.
