* Indirect connection to an object.
*
* Use this overload if you want to connect to an object's method
* which does not match the signal's signature. You can provide
* any delegate to do the parameter adaption, but make sure your
* delegates' context does not contain a reference to the target
* object, instead use the provided obj parameter, where the
* object passed to connect will be passed to your delegate.
* This is to make weak ref semantics possible, if your delegate
* contains a ref to obj, the object won't be freed as long as
* the connection remains.
*
* Preconditions: obj and dg must not be null (dg's context
* may). dg's context must not be equal to obj.
*
* Params:
* obj = The object to connect to. It will be passed to the
* delegate when the signal is emitted.
*
* dg = A wrapper delegate which takes care of calling some
* method of obj. It can do any kind of parameter adjustments
* necessary.
