+/**
+ * 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....
