Some Tk operations don't normally pass through Tkinter. For example, if a
character is inserted into a Text widget by pressing a key, a default Tk
binding to the widget's 'insert' operation is activated, and the Tk library
processes the insert without calling back into Tkinter.
Although a binding to could be made via Tkinter, what we really want
to do is to hook the Tk 'insert' operation itself.
When a widget is instantiated, a Tcl command is created whose name is the
same as the pathname widget._w. This command is used to invoke the various
widget operations, e.g. insert (for a Text widget). We are going to hook
this command and provide a facility ('register') to intercept the widget
operation.
In IDLE, the function being registered provides access to the top of a
Percolator chain. At the bottom of the chain is a call to the original
Tk widget operation.
