[yew-devel] [PATCH yew-widget-toolkit v2 1/3] state: language: add text direction setting

[Dominik Csapak]

Languages can have a text direction that is not left-to-right (LTR), so
add that setting to the LanguageInfo. Expose it only via a builder style
method, since most languages don't need this.
