WIP Patch

This new version adds support for size variants. However, the alignment and stretch size is not good. The improvements from bug 119043 should probably be taken before. There are a couple of rendering issues that would need bug 99620 too.

The ENABLE_OPENTYPE_MATH flag compilation now behaves like this:

- Enabled on ports that can read Open Type Tables (IIUC freetype & cg/cairo on windows). Then the MATH table is read and so any such open type font is supported. Try e.g. http://www.maths-informatique-jeux.com/ulule/mathml_torture_test/

- Disabled on other ports. In that case the data from the MATH table are hardcoded. Currently, only STIX Math is supported as I think it is installed by default on Mac. Hopefully we will be able to replace this with direct access to the MATH table in the future.
