| /** |
| * 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.... |
