For me, the following works:

  .fzoom S 890
  .EQ
  i iota
  .EN

Unfortunately, this also scales the uppercase Greek letters and
other mathematical symbols, which we don't want.  In grops, we
can scale Symbol-Slanted (SS) for the lowercase Greek letters
independently of Symbol (S) for the uppercase Greek letters.
