Good luck!  Feel free to document your findings on the Wiki.

There's a trick to the initialization that's probably not explained as
well as it should be in the docs.  The defaults (other than color, line
width, line style and arrow style) are copied (using *_copy) from a
default object which is stored in defaults.dia.  If you remove
defaults.dia, you will see the defaults in _create being used.

Don't worry, your English is pretty damn good (yet another example that
those who apologize for their bad English are never the worst ones).

Hope this helps, otherwise let me know what other snags you hit.
