Sets whether to calculate the bidirectional base direction
for the layout according to the contents of the layout;
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 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.
