Description hdu@apache.org 2004-03-18 15:04:36 UTC 
During the evolution of the GSL layer a lot of structures, classes, caches ,
functions and algorithms were added to it to describe and work with the
different aspects of font management.

Unfortunately the coherence and stability of the font management suffered due to
these ad-hoc extensions. E.g. one of the most often reported crash reports comes
from inconsistencies between different  caches of font data. Due to these
stability problems and other inconsitencies the caches have to be invalidated
way too often.

Unfortunately some new features require expensive computations and having to
recalculate their results too often makes these features prohibitively costly.

The goal of this task is to clean up the font management structures and the
code, so that extending anything has less risks of side effects and becomes
manageable.

Comment 2 hdu@apache.org 2004-06-23 14:04:28 UTC 
The first step of the font management rework is done in CWS fontlists02:

- the font face objects and the font instance objects can now be extended to
cache extra font technology specific information. 
- the old containers like LIST in font management are replaced by more
appropriate STL containers, which also allows to improve the average complexity
of many important font management operations from O(N)->O(log N) or O(N)->O(1).
- the font management classes are better encapsulated

.
Comment 4 hdu@apache.org 2004-08-04 11:55:25 UTC 
Will use the new infrastructure in the new CWS fontlists*.
Closing.
