    Description copied from class: SequenceOverlay
    
    Checks whether the type of the given image is accepted by this overlay.
    
    Overwritten by subclasses to apply their own rules for acceptance.
    
    Overrides:
    
    typeAccepted in class SequenceOverlay
    
    Parameters:
    
    type - pixel deth of image
    
    Returns:
    
    true when image is a pixel depth of 8
  - initOverlay
```
protected void initOverlay()
```
    Description copied from class: ShuffleOverlay
    
    Initialization of the overlay. This process is separate from the randomization of the overlay.
    
    Overrides:
    
    initOverlay in class ShuffleOverlay
