Return a full copy of the ImageSpec of the designated subimage & level. If there is no such subimage and miplevel it returns an ImageSpec whose format returns true for isUnknown(). This default method assumes no subimages.

    // whose format returns true for isUnknown().
    // This default method assumes no subimages.
    virtual ImageSpec spec (uint32_t /*subimage*/, uint32_t /*miplevel=0*/) {

            ret = images[curSubimage].spec;

    }

    // Return a copy of the ImageSpec but only the dimension and type fields.
    // TODO: Determine if this is necessary.
