[cp-patches] don't attempt to draw zero-length strings

I committed this GdkGraphics2D fix.  Attempts to draw zero-length
strings were causing assertion failures in cairoDrawGlyphVector.

        * gnu/java/awt/peer/gtk/GdkGraphics2D.java (drawString(String,
        float, float)): Return immediately if string is null or
        zero-length.
