The Trunk: TrueType-fbs.24.mcz

Frank Shearar uploaded a new version of TrueType to project The Trunk:
http://source.squeak.org/trunk/TrueType-fbs.24.mcz

==================== Summary ====================

Name: TrueType-fbs.24
Author: fbs
Time: 23 July 2013, 8:03:21.427 pm
UUID: eda594ba-709d-044f-a262-d4ebf17ffd90
Ancestors: TrueType-fbs.23

Make TrueType sit above (and extend) Graphics, thus breaking the cyclic dependency.

The decoupling is pretty rough. By all means make the division between these two packages cleaner!
