Hi, I have just learned how to render text on to the screen. This text is rendered on top of a map. For clarity, what I would like to do is make a white outline or glow (just a couple of pixels wide) around the rendered text.

The fonts come from a ttf file and get transformed into a bitmap texture atlas.

Below is a screen shot: (Bottom left is where the text is)
