示例1: SquashImage
// SquashImage creates a new image with the diff of the specified image and the specified parent.
// This new image contains only the layers from it's parent + 1 extra layer which contains the diff of all the layers in between.
// The existing image(s) is not destroyed.
// If no parent is specified, a new image with the diff of all the specified image's layers merged into a new layer that has no parents.
