B4J Library Vertical Text Engine

Words in Chinese, Japanese and Korean (CJK) can be arranged vertically and I didn't find a good vertical text engine for B4X. In the previous thread I posted, Erel gave a workground solution but it cannot display multiline text and punctuations correctly, The BCTextEngine does not have this support yet, too. So I decided to make one.

I just use Canvas to draw text and use B4XCanvas to measure text.

Example:
