Hi,

I'm having a crack at wrapping a bit of the Clutter library.  The 
Clutter::Animator::set_key function is keeping me entertained at present.  The 
C function is:

ClutterAnimator* clutter_animator_set_key (ClutterAnimator *animator,  GObject 
*object,  const gchar *property_name, guint mode, gdouble progress, const 
GValue *value);

The return value is a pointer to the object itself.  In C I believe this helps 
chain the function; I'm struggling to see why I'd bother in C++.  So can I 
change it to return void (or mabe bool?) or is that messing with the library 
too much?

Ian.
