The implementation mode of a PreviewView.
PreviewView manages the preview Surface by either using a android.view.SurfaceView or a android.view.TextureView. A android.view.SurfaceView is generally better than a android.view.TextureView when it comes to certain key metrics, including power and latency, which is why PreviewView tries to use a android.view.SurfaceView by default, but will fall back to use a android.view.TextureView when it's explicitly set by calling setPreferredImplementationMode(ImplementationMode) with ImplementationMode#TEXTURE_VIEW, or when the device does not support using a android.view.SurfaceView well (for example on LEGACY devices and devices running on API 24 or less).
