The text rendering is now abstracted into the TextRender abstract class. Additionally we have now an abstracted cairo rendering class CairoTextRender which is a subclass of the TextRender class. The CairoTextRender class is still platform independent and needs to be subclassed to implement the few platform dependent methods. You can reuse the cairo based text rendering now by subclassing CairoTextRender for the platform that you need.
