ShapedLines are never wrapped, whereas WrappedLines are optionally wrapped if they are associated with a wrap width. I tried to combine everything because wrapping is inherently optional for the Text element, but we have a bunch of APIs that don't make sense on a line that may wrap, so we need a distinct type for that case.
