Freetype was used a long time ago. Nowadays, helpers libraries around
freetype, such as xft or pango are used. In mozilla products case, both
can be used by selecting a specific backend at runtime or buildtime.
That is done by setting MOZ_DISABLE_PANGO to disable the pango backend
and use the XFT backend instead. Both have their own way to handle
mathml, since mathml layout is tied with the backend.
On Windows, it's another different backend that is used, that is why
mathml support is different there.
In Gecko 1.9, however, it is planned that all platforms will use a new
cairo-based backend, so, hopefully, mathml support will be better. At
least, if they improve it for windows, it will benefit all platforms.
