We generally don't and that's generally not a problem because most _new()
functions don't do much checking. And they shouldn't need to, because libraries
should expect that people will use just g_object_new(). This should really be
avoided - it's far better to always create an instance and have an extra
is_valid() function if necessary.

But if we use the new _construct() functions then hopefully we can still be
told about failures and return a null Glib::RefPtr from our create() functions.
