RE: blur function

Interesting for those implementations that have direct access to the pixel buffer after writing text, which is unfortunately not the case in the toolkit I'm using.

But as an FYI, I went back and took a look at using the lower level layers of the toolkit and discovered a way to implement both outline and a blur. The blur is not 100% ideal - however as we don't mandate any specific algorithm, I believe it's good enough to score as an implementation. So assuming XFSI does one too, I think this feature is safe.
