    1.28 +/**
    1.29 +The CSpriteSet class allows a window server sprite to be drawn to a window.  The class
    1.30 +supports storage of any number of bitmap/mask pairs, though allowing only one of these
    1.31 +bitmap/mask members to be displayed at any one time.  The client of this class should
    1.32 +provide the source bitmap/mask pairs which can be resized to fit a specified rectangle.
    1.33 +Also provided for at runtime is the ability to draw onto the sprite as though it were a
    1.34 +regular CWindowGc and using the same coordinate offsets as the window it exists in.
