Iceweasel: suggested font packages for MathML

[Frédéric WANG]

Dear Debian Mozilla team,

I've just had a look to the dependencies for Iceweasel 8 and I've seen 
the following packages:

* xfonts-mathml: installs "Type1 Symbol", suggests otf-stix and 
recommends ttf-lyx.
* ttf-lyx | latex-xft-fonts: installs TeX's Computer Modern fonts
* ttf-mathematica4.1: installs mathematica fonts

Mathematical fonts are used in Mozilla's MathML implementation to 
display stretchy/large operators correctly. Also, they are useful to 
render various mathematical symbols.

Since at least Gecko 2, TeX and Mathematica fonts are no longer used for 
stretchy/large operators. Instead, we rely on STIX fonts 1.0. These 
fonts should also cover most of the unicode characters needed for 
mathematics. So I think among the dependencies listed above, only 
otf-stix is really useful (Karl Tomlinson may know it better).

Among other free fonts currently suggested:

- Asana Math (support for stretchy/large operators since Gecko 7, good 
support for mathematical symbols)
- DejaVu Serif and DejaVu Sans
