A Boolean value that indicates if the screen saver view was created in a size appropriate for use as a preview.
- macOS 10.0+
The value of this property is
true if the screen saver view was created in a smaller size to be used as a preview, or
false if it was created full-screen for use as a screen saver. Subclasses can check the value of this property to determine if they should change their drawing parameters to something more suitable for display in a smaller frame.
