Is this a problem in practice? I would think not. You want small images in the atlas so they can be batched. The goal of batching is to put many small items into one draw call. For big elements, batching doesn't add that much. An image that will take up more than half the width/height of the atlas will not be batched as it is not considered beneficial at that size. > If a smaller image like 200*200, it can be the atlas texture.
