<para>
Sets whether each complete line should be stretched to
fill the entire width of the layout. This stretching is typically
done by adding whitespace, but for some scripts (such as Arabic),
the justification may be done in more complex ways, like extending
the characters.

<para>
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
   <parameter>layout</parameter> 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.
</para>
<para>
When <link linkend="FALSE:CAPS"><literal>FALSE</literal></link>, the choice between left-to-right and
right-to-left layout is done according to the base direction
of the layout's <link linkend="PangoContext"><type>PangoContext</type></link>. (See <link linkend="pango-context-set-base-dir"><function>pango_context_set_base_dir()</function></link>).
</para>
<para>
When the auto-computed direction of a paragraph differs from the
base direction of the context, the interpretation of
<link linkend="PANGO-ALIGN-LEFT:CAPS"><literal>PANGO_ALIGN_LEFT</literal></link> and <link linkend="PANGO-ALIGN-RIGHT:CAPS"><literal>PANGO_ALIGN_RIGHT</literal></link> are swapped.</para>
