Remove accidentally included text.
Fix transform_anchor to work with anchors of type absolute.
sl1: Fix label and textbutton.

Now that we're creating the widgets directly, we need to apply the
function wrapper to the results of _label and _textbutton.
Allow non-ascii identifiers to be used as character names.

There are a couple of caveats here, since non-ascii identifiers
can't be used in python code.

* The names must be defined with the define statement.
* The names can't be accessed in python code.

Stil, something like:

    define 彁 = Character("Boy who is not able satisfactorily to explain what a Hrung is, nor why it should choose to collapse on Betelgeuse Seven")

    彁 "Don't forget your towel."

should work.
