It's "Filter Effects 1.0", and the spec can be found here:

   https://dvcs.w3.org/hg/FXTF/raw-file/tip/filters/publish/Filters.html

As agreed in earlier discussions in the taskforce we're making one spec.  
It includes both SVG and CSS definitions.

No, the Filter Effects 1.0 spec replaces the SVG Filters 1.2 spec.

We are defining a simpler syntax for filter effects, however I'm not  
convinced it's a good idea to ignore SVG Filters which are widely  
implemented at this stage, and considering that diverging from that  
potentially makes it harder to reuse existing code.

The general idea so far has been: use svg <filter> markup for the more  
complex filter effects, use css shorthands for simple filter effects.
