topic for Sydney F2F

All,

I would like to have a discussion on SVG and CSS compositing.
Specifically, how are we going to deal with

-          Group invariance: is it important? What are the difficulties in implementing them?

-          Background calculation: how is it done when doing compositing operator other than Porter-Duff?

-          CSS filters: how is the background calculated in an HTML context?

There was a discussion on the mailing list a couple of weeks ago. For the conference I'll summarize the conclusions.
