This PR refactors implementation of Paragraph::render. It allocates LineComposer trait object on heap memory and calls its methods via dynamic dispatch. However it can be easily changed to static dispatch with allocating the object on stack.

This PR does the change as refactoring. No rendering logic has changed.

I'm a big fan of anything that simplifies complexity like this.
I can merge as-is and apply my nit after if you don't have time to make the suggested change.
