Yes, certainly, I found 27 references to it in my own DVI driver family
code, and here is a sample snippet of how it is used:

    /* Compute the font magnification from the at_size and design_size
       specified in the DVI file, further modified by TeX-time and
       DVI-time magnifications, and output device resolution.  We need
       this information in openfont() which is called below. */
   tfontptr->font_mag = (UNSIGN32)(
        (actfact(MAGSIZE((double)tfontptr->at_size/
            (double)tfontptr->design_size)) *
        ((double)runmag/(double)dvimag) *
        actfact(mag) *
        (double)RESOLUTION * 5.0) + 0.5);
