    37  * This interface defines the set of calls that pipeline objects

    38  * can use to pass on responsibility for performing various

    39  * image copy commands.

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

    41  *    - copyImage: These methods simply copy the pixels

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

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

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

    45  *      scaling the source image.  The src and dest rectangles

    46  *      are used to specify the scale.

    47  *    - copyImageBg: These methods behave the same as the

    48  *      copyImage methods except they substitute the given

    49  *      background color for any transparent pixels.

    50  *    - scaleImageBg: These methods behave the same as the

    51  *      scaleImage methods except they substitute the given

    52  *      background color for any transparent pixels.

    53  *    - transformImage....
