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....
