+/**
+ * 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....
