* ext/tk/*: Support new features of Tcl/Tk8.6b1 and minor bug fixes.
( [KNOWN BUG] Ruby/Tk on Ruby 1.9 will not work on Cygwin. )
* ext/tk/*: Unify sources between Ruby 1.8 & 1.9.
Improve default_widget_set handling.
* ext/tk/*: Multi-TkInterpreter (multi-tk.rb) works on Ruby 1.8 & 1.9.
( [KNOWN BUG] On Ruby 1.8, join to a long term Thread on Tk
callbacks may freeze. On Ruby 1.9, cannot create a second
master interpreter (creating slaves are OK); supported master
interpreter is the default master interpreter only. )
* ext/tk/lib/tkextlib/*: Update supported versions of Tk extensions.

Ttkとは，テーマ指定可能な新しいウィジェット集合です．\
|
||
Ttk::Treeviewウィジェットは\
|
||
Ttkウィジェットセットに含まれるウィジェットの一つで，\
|
||
それが保持する木構造のデータそのものまでは表示することなく，\
|
||
示したい情報をマルチカラムで表示させることができます．
|
||
このサンプルは，複数のカラムを持ったリストボックスを作成する簡単な例です．
|
||
各カラムのタイトル(heading)をクリックすれば，\
|
||
そのカラムの情報に基づいてリストの並べ替えがなされるはずです．\
|
||
また，カラムのタイトル間の区切り部分をドラッグすることで，\
|
||
カラムの幅を変更することも可能です．
