+Bidirectional Text
+==================

+-----------
+This patch adds proper support for Right-To-Left languages. (such as Farsi, Arabic or Hebrew)
+
+Texts combining both RTL and LTR languages are displayed correctly in images.
+This is achieved using the GNU FriBiDi library, which is an additional dependency for this patch.
