I'm currently trying to get text layout working in a game and the /only/ text control provided by the engine is one that "can" be editable, since it's assumed for non-editable text you'd just use graphics. However, this game has a lot of dialogue and must be translated into multiple languages so that's not a realistic option.

It's a fucking nightmare. It turns out it uses Cairo internally so that's not bad, but I /need/ to know where the last glyph is and answering questions about how your text actually is going to be laid out in the end is next to impossible everywhere I look.

Since, again, this has to work in multiple languages including CJK I am loathe to code my own text control but I may have to.
