Do we need this in the public API? If it is only called internally from the
deferred texture data -> image factory function perhaps it could be private.

+1 to privatization.

BTW -- (other) Brian and I have changes in-flight where we can build more than
on mipmap for a given image, depending on the compatibility-mode we're in for
sRGB...

Done.
