The current list of known issues are:

Font: Not all ttf table information is being used (hinting, ..)
http://developer.apple.com/fonts/TTRefMan/RM06/Chap6fvar.html
http://developer.apple.com/fonts/TTRefMan/RM06/Chap6gasp.html

etc...

if there are some ttf 'experts' available .. we would love to discuss

Font/Renderer: The 'Java' font rendering is buggy
The produced outlines by the font parser are not rendered correctly.

GPU/Renderer: AMD only produces an all white picture
tests on ATI/AMD shows that no pixel are being visible

Implementation: Enhance .. enhance
:)

Architecture: Refine API ..
with more use cases and discussion we shall make the API stable and more sane

To accomplish all of this we sure need everybody being interested and using it.
I will open up bugzilla entries for all of this soon.

Hope you have fun.

Cheers, Sven
