Related notes:

What is the difference between "feathered" and "blurred"? Are there different parameter(s) for the former than the latter? If this is just a request for blurring, then this will map to the CSS3 Text Decoration module's text-shadow property.

Feather == blur for both text-shadow and text-outline
