ruby--ruby/ext/tk/sample/tkextlib/tile/demo.rb
ocean 7b1bdb68e9 * ext/tk/sample/tkextlib/tile/demo.rb: followed previous changes.
* ext/tk/lib/tkextlib/tile/t*.rb: aliased class names starting with 'T'
  to non 'T' ones. (ie. Tk::Tile::TButton -> Tk::Tile::Button)
  [ruby-dev:26724]

* ext/tk/lib/tkextlib/tile.rb: ditto. (autoload support)
