/* fribidi_shape_arabic - do Arabic shaping
 *
 * The actual shaping that is done depends on the flags set.  Only flags
 * starting with FRIBIDI_FLAG_SHAPE_ARAB_ affect this function.
 * Currently these are:
 *
 *	* FRIBIDI_FLAG_SHAPE_MIRRORING: Do mirroring.
 *	* FRIBIDI_FLAG_SHAPE_ARAB_PRES: Shape Arabic characters to their
 *					presentation form glyphs.
 *	* FRIBIDI_FLAG_SHAPE_ARAB_LIGA: Form mandatory Arabic ligatures.
 *	* FRIBIDI_FLAG_SHAPE_ARAB_CONSOLE: Perform additional Arabic shaping
 *					   suitable for text rendered on
 *					   grid terminals with no mark
 *					   rendering capabilities.
 *
 * Of the above, FRIBIDI_FLAG_SHAPE_ARAB_CONSOLE is only used in special
 * cases, but the rest are recommended in any environment that doesn't have
 * other means for doing Arabic shaping.  The set of extra flags that enable
 * this level of Arabic support has a shortcut named FRIBIDI_FLAGS_ARABIC.
