WidgetBuildRecorder class abstract
A recorder for measuring the performance of building a widget from scratch starting from an empty frame.
The recorder will call createWidget and render it, then it will pump another frame that clears the screen. It repeats this process, measuring the performance of frames that render the widget and ignoring the frames that clear the screen.
