setAutoDir
Sets whether to calculate the base direction for the layout according to its contents.
When this flag is on (the default), then paragraphs in @layout that begin with strong right-to-left characters (Arabic and Hebrew principally), will have right-to-left layout, paragraphs with letters from other scripts will have left-to-right layout. Paragraphs with only neutral characters get their direction from the surrounding paragraphs.
When false, the choice between left-to-right and right-to-left layout is done according to the base direction of the layout's PangoContext. (See method@Pango.Context.set_base_dir).
When the auto-computed direction of a paragraph differs from the base direction of the context, the interpretation of %PANGO_ALIGN_LEFT and %PANGO_ALIGN_RIGHT are swapped.
