TextButton::changeWidthToFitText & lnf

Jules, would you be ok to add a  virtual void changeTextButtonWidthToFitText (TextButton&) = 0;

in the Button::LookAndFeelMethods that TextButton::changeWidthToFitText() would call?

So that we could override it in our LnFs as we can do for the ToggleButton

Yes, that seems like a very sensible request!
