java.awt.image.ReplicateScaleFilter
public class ReplicateScaleFilter
This filter should be used for fast scaling of images where the result
does not need to ensure straight lines are still straight, etc. The
exact method is not defined by Sun but some sort of fast Box filter should
probably be correct.
Currently this filter does nothing and needs to be implemented.

public void setDimensions(int width, int height)
ImageProducer
indicates the size of the image
being produced using this method. A filter can override this
method to intercept these calls from the producer in order to
change either the width or the height before in turn calling
the consumer's setDimensions
method.
