The MacOS module may be available on Mac OS X, but it doesn't have a SchedParams() method, and there's no need to call it anyway.

Use "is" and "is not" when comparing with None or type objects.

test_winreg.py ("didn't" -> "Didn't" and "Didnt" -> "Didn't").

There is a minor style issue involved: Guido seems to have preferred English
grammar (behaviour, honour) in a couple places. This patch changes that to
American, which is the more prominent style in the source. I prefer English
myself, so if English is preferred, I'd be happy to supply a patch myself ;)

Also fix spelling tupel -> tuple.

has reviewed this, too.

this patch adds a fast _flatten function to the _tkinter
module, and imports it from Tkinter.py (if available).

this speeds up canvas operations like create_line and
create_polygon.  for example, a create_line with 5000
vertices runs about 50 times faster with this patch in
place.

OptionMenu is modified.  Somewhat rewritten and elaborated by myself.

class _setit: The constructor now takes an optional argument
`callback' and stashes this in a private variable.  If set, the
__call__() method will invoke this callback after the variable's value
has changed.  It will pass the callback the value, followed by any
args passed to __call__().

class OptionMenu: The constructor now takes keyword arguments, the
only one that's legally recognized is `command', which can be set to a
callback.  This callback is invoked when the OptionMenu value is set.
Any other keyword argument throws a TclError.

more than one window argument.

didn't properly handle the hex numbers returned.

and Toplevel class constructors.  This means that if the window
manager closes the window, the Python-side Tkinter data structures
will be destroyed correctly.  (Most apps do this anyway, and it's
recommended practice; I see no reason why making it the default
behavior could be bad.)

bindings to a dictionary _tagcommands which was otherwise unused.
(This was checked in accidentally with rev. 1.125 and not deleted with
rev. 1.127 when the other half of this code was removed -- although
even as originally checked in the _tagcommands variable was never
used.)

arguments.  [Slightly changed from submitted patch.]

(The difference between grid_remove() and grid_forget() is that the
former remembers the options for the slave.)

than was worth it: when deleting a canvas item, it would try to
automatically delete the bindings for that item.  Since there's
nothing that says you can't reuse the tag and still have the bindings,
this is not correct.  Also, it broke at least one demo
(Demo/tkinter/matt/rubber-band-box-demo-1.py).

so the preferred name for them is tag_lower, tag_raise
(similar to tag_bind, and similar to the Text widget);
unfortunately can't delete the old ones yet (maybe in 1.6)
