Hmm, ok I was considering adding the truetype code for this into khtml 
separately, ideally I'd like direct access the FT_Face that Qt is using for 
the QFont, however this is private to the Qt API for obvious reasons.

I can think of two options:-

1. I could add QFONT_HAS_XHEIGHT to the Qt header and then make the code 
conditional on having a patched qt-copy
2. I could add the code to loadup a freetype font and query the metrics in the 
css code. 

Option 1 seems much cleaner, but would restrict its usefulness to developers 
building qt-copy.
Option 2 is horrid, but would mean that we could access other detailed font 
metrics if we needed to for other purposes (more exact spacing).

Opinions/Rants/Flames?
