Could you post your PDF here? It might be helpful for many people. Not everyone will use the measurements that you use, but it might help others develop something that they need.
If this is something that many people want, please add it to the issues list at bitbucket. If everyone wants it quickly, then we could take up a collection to pay someone to code it up. Roman codes the high priority bugs and features. (Of course he wouldn’t mind if anyone sent him a donation – I’m working on a way to do this.)
