commit 907d5ae48442a946e5107c0239f8c69cc612ea78
Author: Nate Stedman <natesm gmail com>
Date: Sun Nov 28 23:14:37 2010 -0500
[text] Started new text system.
* Ease's new text system is a more featured replacement for the
previous use of ClutterText.
* EaseText, which manages a PangoLayout to render, format, and
modify text.
* EaseTextActor and EaseTextElement modified to use EaseText.
* Transformations namespace removed, as it only contained color
transformations. These have been moved to EaseColor.
* Added PangoColor support to EaseColor
* Added modified Pango vapi, as there is a bug in the shipped
version.
* Other classes updated to support EaseText
