Then I would be very surprised if pango fills the role of a companion
text library for cairo. It will have to be something else  since there
is a real need for one that can handle some simple cases but also
complex text layout problems if desired.  Its a shame you feel this
way I think there are a lot of good things about pango that would be
useful outside of gtk but 850k of code is not needed to solve this
problem.
