/**

 * This interface defines the set of calls that pipeline objects

 * can use to pass on responsibility for performing various

 * image copy commands.

 * There are 3 types of image copies handled by this class:

 *    - copyImage: These methods simply copy the pixels

 *      from the src to dest, either from (0, 0) (implicit)

 *      or from a given (sx, sy) location.

 *    - scaleImage: These methods copy from src to dest while

 *      scaling the source image.  The src and dest rectangles

 *      are used to specify the scale.

 *    - copyImageBg: These methods behave the same as the

 *      copyImage methods except they substitute the given

 *      background color for any transparent pixels.

 *    - scaleImageBg: These methods behave the same as the

 *      scaleImage methods except they substitute the given

 *      background color for any transparent pixels.

 *    - transformImage....
