Custom Shape Orientation Guide

[Regina Henschel]

Hi all,

I have been working with custom shapes for quite a while now. Again and 
again the questions come up "How is the property actually defined in the 
file format?", "How is the property realized in core?" or "Where is the 
property set or converted in core?". I have now tried to collect answers 
and provide links.

The whole thing reflects my state of knowledge. If you find bugs, please 
report them (or fix them directly :) ). Also, if you miss something or 
things are unclear, please let me know. And if you want to add 
something, just do it. It is a wiki after all. Same holds, when you 
think the linguistic needs to be improved.

Kind regards,
Regina
