> This patch adds rudimentary support for the dr3d:scene element and its children by introducing a 3D shape. The 3D support in ODF is pretty simple: it just defines 4 different object types: cube, sphere, extrude and rotate as well as a scene element that acts a bit like a group (draw:g).

This makes OOo/LO not show the shapes when they are loaded again after a roundtrip through Karbon. I have not been able to analyze why Karbon saves back all shapes with layer="" when the infile clearly has layer="layout".
