Immediately returns a copy of the last rendering from Chrome, or null if no rendering has occurred yet. Chrome also renders the page loading, so if you want to see a complete rendering, only start this task once your page is loaded (which you can detect via LoadingStateChanged/FrameLoadEnd or your own heuristics based on evaluating JavaScript). It is your responsibility to dispose the returned Bitmap. The bitmap size is determined by the Size property set earlier.
