+Summary: [Windows] DoubleBuffer/TextRenderer problem
+When using the new 2.0 TextRenderer class on a double buffered surface, the
+text is drawn on top of the old text, resulting in bold, unreadable text. 
+See screenshot.  (This only happens on Windows because TextRenderer falls
+back to using Graphics.DrawString for X11.)
+This happened with the old DoubleBuffer code as well as rolf's new code.  I
+don't really know where to start with this.
+Also, System.Drawing provides the BufferedGraphics class.  Would it be
+better to use that instead of our own?
