ruby--ruby/ext/tk/lib/tktext.rb
nagai 9a47a04607 tkcanvas.rb :
* Although requiring manual control of GC, memory eating problem
    of TkCanvas Items is fixed. Probably, a time when GC should run
    is only after removing many canvas items. GC's cost is large
    and the man who knows proper timing to start GC is the man who
    create the script. So, Ruby/Tk doesn't start GC automatically.

tktext.rb :
  * add some methods and bug fix

tk.rb :
  * add widget destroy hook binding to TkBindTag::ALL
