Optional options: ChangeAlphaRenderOptionsStatic requestReturns a shared GPUDevice, initialising it on the first call.
All renderers share the same adapter and device to avoid exhausting
browser GPU resource limits.
The device is requested with timestamp-query enabled if the adapter
supports it, so profiling-capable renderers (e.g. DmdRenderer) can use
that feature without a separate device request.
