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.

Here is a simple and fast algorithm for implementing tts:textOutline blur radius:
