[gtk+/quartz-integration: 438/563] gail: Remove AtkText implementation from GailScale



commit ee7c9d7a5af44e78f5c727da9a31164867f18d1f
Author: Benjamin Otte <otte redhat com>
Date:   Sun Jun 26 23:00:49 2011 +0200

    gail: Remove AtkText implementation from GailScale
    
    AtkText should only be implemented by text editing widgets. For just
    giving out a small text string, AtkObject::name should be used.
