This draft patch adds a small function called getCoreInfo (maybe
getMetadata would be better?). It allows external apps to get
information about the _running_ compiz process.
The metadata directory is the most important because it will
be needed to read non-standard metadata directly from the
XML file. The others are probably useful for image locations
etc.
Any comments, or is there any extra info that could be included?
I will probably change the information to return a dict rather
than a series of values because it marshals better.
