I used the first mipmap level as an example of the effect at any given
mipmap reduction level, not an artificial limit. Mipmap level is
determinied by virtual viewing distance to the object and image
filtering mechanisms. For any given mipmap level, a mipmap for a
higher resolution texture compared to a mipmap of a lower resolution
texture will have the same size ratio as their base images. So the
initial texture size makes a substantial difference.
