DESCRIPTION
This function finds the base direction of a single paragraph,
as defined by rule P2 of the Unicode Bidirectional Algorithm available at
http://www.unicode.org/reports/tr9/#P2.
You typically do not need this function as
fribidi_get_par_embedding_levels() knows how to compute base direction
itself, but you may need this to implement a more sophisticated paragraph
direction handling. Note that you can pass more than a paragraph to this
function and the direction of the first non-neutral paragraph is returned,
which is a very good heuristic to set direction of the neutral paragraphs
at the beginning of text. For other neutral paragraphs, you better use the
direction of the previous paragraph.
RETURNS
Base pargraph direction. No weak paragraph direction is returned,
only LTR, RTL, or ON.
Possible values for a FriBidiParType are as follows:
