If we're creating a CompositedMultiFrameImage with only a single source image and it's a TileSetFrameImage, just use the Mirages in that TileSet rather than creating a whole new set of BufferedImages to composite them into. This halves the image memory used by anything that's just colorizing and transforming its images and doesn't really need composition.
