Incorrect alignment when using Wrap::None

[nickguletskii]

When calling layout with Wrap::None, the w property of VisualLine is not updated, which breaks alignment options such as Align::center:

cosmic-text/src/shape.rs

Lines 664 to 670 in bfb5eef

	if wrap == Wrap::None {
	for (span_index, span) in self.spans.iter().enumerate() {
	current_visual_line
	.ranges
	.push((span_index, (0, 0), (span.words.len(), 0)));
	}
	} else {

Besides, I don't really understand why Wrap::None has to be handled differently from other wrapping options. I might be wrong here, but wouldn't replacing fit_x - word_width >= 0. with wrap == Wrap::None || fit_x - word_width >= 0. inside the second branch be sufficient? Is this done for performance reasons?
