Export the shadow factory

Browse Source 
The elementary guys would like this as an API, and I don't see any
reason to refuse -- this is quite nice shadow painting code :)

For some reason, gobject-introspection can't seem to cope with
MetaWindowShape. I'll look into it a bit later, but for now, mark
the function it has trouble with as (skip).
