Hi Hans & Aditya

Please be patient as I am not a developer just someone who writes
documents.

I discovered the integral symbols starting at the double integral
are now composed by repeating the normal integral symbol
n-times. However in an earlier email I commented that they didn't
look right (something to do with setting the displaystyle (I think))

Then I discovered the Asana math font which has "correct" glyphs
The missing symbols for math-vfu.lua are

Asana math font
0x222B normal integral \int
0x222C double integral \iint
0x222D triple integral \iiint
0x222E contour integral \oint
0x222F surface integral \oiint
0x2230 volume integral \oiiint

I also need the space-time integral \iiiint (4 i's) but could
not find it in the Asana font

Note for the other math stuff the Asana math font does not work
like vectors and such. For $\vec{r}, \vec{R}$ the vector symbol is shifted
to the right and not aligned above the character (hope this make some sense otherwise
forget it for the moment).

Kind regards
