Thanks. Yes, we should get rid of the InteropGrabBag for 3D properties
in the long run and implement them natively, including rendering.

I think your document makes sense. Perhaps thinking about the markup for
3D rotation of custom shapes (2.4 in your document) would be good,
that's a quite frequent feature, and it's no clear how to represent that
in ODF. I mean OOXML markup like:

          <a:scene3d>
            <a:camera ...>
              <a:rot lat="..." lon="..." rev="..."/>
            </a:camera>
          </a:scene3d>

In any case, once somebody will have time to implement these, it'll be
useful to have a proposal how to represent the feature in ODF.
