Fixes some tree rendering problems where lines were not properly drawn at some levels during some circumstances. * Change the API back to only allow one root. * Now uses a stack based approach to rendering instead of recursion. * Removes the need for measuring the whole tree in advance. Leave this up to each child to render.
