Works for my files I think, but maybe not for everyone else :/

Yes, and not really what I want (for my files).

Just display might not satisfy everyone, so enhanced path shape I will be 
looking at.

Until Karbon does at well, that might be a workaround. But then those program 
concepts are just work-flow artifacts, given the composed nature of the 
document type :)

So those effects cannot be mapped to ODG? Could't I simply embed SVG into ODG?
