Hi Kami,

we very briefly chatted about this in Paris - indeed, there's code
already that renders some subset of the MS smart arts - look here:

 http://cgit.freedesktop.org/libreoffice/core/tree/oox/source/drawingml/diagram

Since MSO annoyingly does not write any fallback rendering to ooxml,
it's one of the larger interop gaps we had - I consider it mandatory
to have a smart art view-only implementation available in oox.

Some concepts in the talk here:

Beyond that, I had a prototype running with a special shape in svx,
that would permit the same kind of editing that you have in your
extension. Let me hunt for that code & see what needs to be done for
getting it to run again - not sure how much time I'd be able to
invest for hacking on that feature, but I'll gladly help with any
questions.

Also worth noting is that OOo once had an attempt from RedFlag
(IIRC), remnants of that maybe in CWS impressintelligentgroup01 - I
dislike that approach, since it ignores MSO interop completely. In
my mind, interop is the point to start from, architecture-wise -
not the one to eventually get to, and then discover that some
features just don't work ... ;)

All of this, as should be apparent, really is only achievable with
access to core code, so having an extension-only solution for this
simply won't cut it.

Cheers,

-- Thorsten
