Is the intent of this to introduce "blur" as a new backend operation, so 
that backends can accelerate blur as appropriate?  If not, I'd suggest 
that this be part of the cairo-utils librarly that's been discussed for 
a while, and that would act on an input surface (perhaps via an exposed 
acquire/release api?)..
