 Most arguments to widgets have been made keyword-only
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

 Passing all but the very few first arguments positionally in the constructors
 of Widgets is now keyword-only. In general, all optional arguments are keyword-only.

 ``RadioButtons.circles``
 ~~~~~~~~~~~~~~~~~~~~~~~~

 ... is removed.  (``RadioButtons`` now draws itself using `~.Axes.scatter`.)

 ``CheckButtons.rectangles`` and ``CheckButtons.lines``
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

 ``CheckButtons.rectangles`` and ``CheckButtons.lines`` are removed.
 (``CheckButtons`` now draws itself using `~.Axes.scatter`.)

 Remove unused parameter *x* to ``TextBox.begin_typing``
 ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

 This parameter was unused in the method, but was a required argument.

 ``MultiCursor.needclear``
 ~~~~~~~~~~~~~~~~~~~~~~~~~

 ... is removed.
