        Thanks again for the patch.

        One small omission: I'd suggest adding the following
        to the copy constructor:


--- snip
    _label_xywh[2]    = o->_label_xywh[2];
    _label_xywh[3]    = o->_label_xywh[3];
    _usericon         = o->usericon();
    _userdata         = o->userdata();          // <-- ADD THIS
    _parent           = o->_parent;
--- snip


        It'd be nice if the compiler could warn about omissions
        regarding uninitialized data in constructors :/

        Maybe there is a flag, and I just don't know what it is,
        but I'd sure like to use it..
