// Purpose:
// The implementation of this interface provides a mechanism for optimizing the
// copy/pasting of images. Specifically, it provides a means for NOT creating duplicates
// of the low res proxy image which is embedded with each image at Place time. Instead,
// the low res is tracked by this list and when an image is copied and pasted, we simply
// bump our persistant reference count in the image list instead of duplicating all
// of the image data. See also IScrapImageList.h.
