TextraLabel wrap will not respect prefWidth for long words

Hi!

I'm using the TextraTypist library (which is awesome by the way!) for the labels in my game.

Something I noticed is that labels won't wrap long words properly. It looks like TextraLabel with wrap does not respect the preferred width for long words:

Code (using the default skin at https://github.com/czyzby/gdx-skins/tree/master/default/skin):

public class MyGdxGame extends ApplicationAdapter {

  private Stage stage;
  private Skin skin;

  @Override
  public void create () {
    stage = new Stage(new ScreenViewport());

    skin = new Skin(Gdx.files.internal("uiskin.json"));

    TextraLabel label = new TextraLabel("xdddddddddddddddddddddddddddddddddddddddddddddddddddddddd", skin);
    label.setWrap(true);

    Table table = new Table();
    table.debug();
    table.add(label).prefWidth(100).row();

    Stack stack = new Stack(table);
    stack.setFillParent(true);

    stage.addActor(stack);
  }

  @Override
  public void render () {
    ScreenUtils.clear(0, 0, 0, 1);
    stage.act();
    stage.draw();
  }

  @Override
  public void dispose () {
    stage.dispose();
    skin.dispose();
  }
}

The behavior here is different from Label, and I've been aware of this for some time. I do want to make the wrapping behavior match Label at some point in the near future, it's just a ton of work.

Right now, the rules wrapping follows are:

• It never breaks up individual words regardless of length.
  • This is why very long words can be longer than the preferred width.
  • Without hyphenation logic, which is a can of worms, breaking up words can change their meaning.
    • THEPOWEROFCHRIS
    • TCOMPELSYOU!
    • "Huh, why isn't the exorcism working? Are you praying to Chris or something?"
• If placing the second or later word on a Line would make the Line longer than the Layout's targetWidth, it moves the new word to the next Line.
• Certain characters count as whitespace, and are replaced with a newline, and certain characters permit being used as a line-break point (such as '-'), and are retained along with a newline after them.

Thanks for the elaborated answer Tommy. For the time being, I will use a workaround and manually break long words. Cheers!
