It makes use of eqn's "special" feature.  Not sure if this
is the most elegant way of doing it, but at least it allows
adjusting the subscript kern (for the lower bound of the
integral) and what eqn believes to be the height and depth
(I tried to make the math axis of sub- and superscript
correspond to approximately the center of the "bulbs"):

  .de IS
  .ds 0s \fS\Z'\v'.15m'\b'\N'243'\N'245''\v'-.15m''\h'0.9m'\fP
  .nr 0w 0.9m
  .nr 0h 1.27m
  .nr 0d .79m
  .nr 0skern .3m
  ..
  .EQ
  define int %{ special IS "" }%
  .EN

Hmmm, I think it would have been better to use the same font
family for math as for body text (like on page 28, "u = u(x)").

I think fzoom does this:
