Combine the given images to create an atlas map. Each image must be square with dimensions equal to a power of
two, eg. 32×32 or 128x128. All images must be of equal size.
UV type must be a RectangleI or struct containing RectangleIs. The new mapping will offset the positions
of those rectangles to match those of the newly made image.

If given only one image, returns it unchanged.
