 *  Origin is the coordinate in the new Raster's coordinate system of

 *  ancestor which has no parent.)
 *
 *  Note that this constructor should generally be called by other
 *  constructors or create methods, it should not be used directly.
 *  @param sampleModel     The SampleModel that specifies the layout.
 *  @param dataBuffer      The DataBufferShort that contains the image data.
 *  @param aRegion         The Rectangle that specifies the image area.
 *  @param origin          The Point that specifies the origin.
 *  @param parent          The parent (if any) of this raster.
