Updated Working Draft: Requirements for Chinese Text Layout 中文排版需求

Updates to Requirements for Chinese Text Layout include the following.

• Zhuyin figures updated
• Various graphic examples of annotations added
• New section containing examples of Zhuying annotations
• Aijie Zhang added to list of editors
• Various code fixes and typos corrected

We are in the process of adding Simplified Chinese translations of all the text, but the work is still in progress. All markup created during this process so far has been hidden in this document using CSS. It will be unhidden in a future Working Draft, once the work is completed.

A detailed list of changes, including diffs, can be found in the github commit log.
