       Compare specified regions of two M-texts ignoring cases. The mtext_case_compare() function compares two
       M-texts mt1 and mt2, character-by-character, ignoring cases. The compared regions are between from1 and
       to1 in mt1 and from2 to to2 in MT2.  from1 and from2 are inclusive, to1 and to2 are exclusive.  from1
       being equal to to1 (or from2 being equal to to2) means an M-text of length zero. An invalid region
       specification is regarded as both from1 and to1 (or from2 and to2) being 0.

           This function returns 1, 0, or -1 if mt1 is found greater than, equal to, or less than mt2,
           respectively. Comparison is based on character codes.
