Because a scrolled canvas is not a standard widget of Tcl/Tk. :-)

As I showed my last mail, it is easy to create a TkScrolledCanvas 
widget class. However, it is not clear how much configurable the 
class is required to add it to Ruby/Tk standard libraries. 

Of course, we can allow full configuration of all part of the widget 
by delegate_alias method and so on. But, is it realy right solution?
Maybe it only create many of configuration keys which have a very 
long name and rare necessity. Possibly, it is not so easy to decide 
the balance point. If a widget class is entried as a standard library, 
it is a litte difficult to change specification of the widget.
