 * small bug fix
 * rename 'no_create' option to 'without_creating'
 * add TkWindow#pack_in,  TkWindow#grid_in,  TkWindow#place_in
 * add TkWindow#bind_class and TkWindow#database_class
   If defined specific_class (@db_class), bind_class returns @db_class.
   In other case, bind_class returns TkWinow#class().
   It is useful for binding.
   TkWindow#database_class is defined for querying the option database.
   It's same to TkWinfo.classname(self).
 * add TkBindTag.new_by_name and TkDatabaseClass for binding to database class
 * check varname whether already exsist or not. (TkVarAccess.new)
 * TkTextWin#bbox returns an array of four numbers
 * autoload TkDialog2, TkWarning2
 * scan event callback arguments and convert to proper type
 * TkBindTag.new accepts a block ( TkBindTag.new(context){callback} )
 * If given taglist, TkWindow#bindtags(taglist) returns taglist
 * add TkWindow#bindtags=(taglist)
 * Tk.focue and Tk.focus_lastfor return nil if there is no target widget.
 * Tk::Wm.client returns the argument string when setting name
 * TkGrid.columnconfiginfo and rowconfiginfo given a slot return a number.
 * TkWindow.grid_columnconfiginfo and grid_rowconfiginfo :: ditto
 * rename and define alias :: TkOption ==> TkOptionDB
 * define alias :: TkTimer ==> TkAfter
 * some instance methods change from public to private
 * some TkComm methods change to module functions
   (help to treat return values from Tk)
 * add support for -displayof option to some TkWinfo methods

        It allows to create ruby objects for widgets created on Tcl/Tk.
         (e.g. TkButton.new('widgetname'=>'.bbb', 'no_create'=>true) )
        It is useful for some Tcl/Tk Mega Widgets.
