/**
* 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....
