Thanks. Looks good on linux (i.e. linespacing problem solved and no other
problems with formulas)

I did not compare the settings to the ones attached to this issue, but to the
ones currently shipped with OOo/the one in cvs (md5sum
dd604fd024ebb8efc7872e2f5dd4b927)
The very first one attached to the issue has all metrics set to zero btw.
(already different to the one in cvs), the second one marked with "created with
fontforge" has the Typo-values set, so is already different from the first one
and from the one in cvs..

There is no specific reason. I determined the values by trial and error and the
Win-Values made the difference... 
I didn't touch those that did not make a difference on linux. And in the
"original" version, the Typo values are set to zero.

As http://fontforge.sourceforge.net/editexample5.html#baseline reads the
Typo-Values are used on windows, that's why I didn't touch them and want to have
them reset to the values from cvs that are known to work. They may need some
minor finetuning, but values of 2000+ offset just seem wrong to me. (and
apparently caused problems) It also writes that Windows-programs often don't
care and take the win-values instead (and since simonAW tested the values on
windows and said they were OK I still think they'll don't cause the
display-problem in the attached formula-doc)
In http://fontforge.sourceforge.net/fontinfo.html#TTF-Metrics it already reads:
"The Typographic Ascent and Typographic Descent are /supposed/ to represent the
line spacing of the font on the windows platform. Sadly very few applications
actually use them (most applications use the Windows Ascent/Descent described
above)."

> And how did you get/calculated these values?

I did not calculate them. They were determined by modifying the value,
installing the font, launching OOo, test whether the effect still is visible,
modify it again, ....
