ProfilingOverlay class

An overlay that draws frame-processing timing information on top of the video preview.

It displays the overall frame processing time together with per-stage engine timings, which is useful when investigating scanning performance without parsing log output. Add it to a DataCaptureView via DataCaptureView.addOverlay.

This is a diagnostic aid that mirrors an internal capability of the native SDKs; it is experimental, subject to change, and may be removed in future versions.
