If we have a preset where there is no OOXML preset, then writing the
full custom geometry sounds good to me.

I think if our feature set there is more rich than what OOXML allows,
then either we can just say this is not our problem or if this really
bothers somebody, we can change our preset to use shading which is
simple enough for OOXML to handle.
The trouble in the second case is to make sure we don't break old
