/**
 * `UBiDiOrder` indicates the order of text.
 *
 * This bidi transformation engine supports all possible combinations (4 in
 * total) of input and output text order:
 *
 * - <logical input, visual output>: unless the output direction is RTL, this
 * corresponds to a normal operation of the Bidi algorithm as described in the
 * Unicode Technical Report and implemented by `UBiDi` when the
 * reordering mode is set to `UBIDI_REORDER_DEFAULT`. Visual RTL
 * mode is not supported by `UBiDi` and is accomplished through
 * reversing a visual LTR string,
 *
 * - <visual input, logical output>: unless the input direction is RTL, this
 * corresponds to an "inverse bidi algorithm" in `UBiDi` with the
 * reordering mode set to `UBIDI_REORDER_INVERSE_LIKE_DIRECT`.
 * Visual RTL mode is not not supported by `UBiDi` and is
 * accomplished through reversing a visual LTR string,
 *
 * - <logical input, logical output>: if the input and output base directions
 * mismatch, this corresponds to the `UBiDi` implementation with the
 * reordering mode set to `UBIDI_REORDER_RUNS_ONLY`; and if the
 * input and output base directions are identical, the transformation engine
 * will only handle character mirroring and Arabic shaping operations without
 * reordering,
 *
 * - <visual input, visual output>: this reordering mode is not supported by
 * the `UBiDi` engine; it implies character mirroring, Arabic
 * shaping, and - if the input/output base directions mismatch - string
 * reverse operations.

typedef struct UBiDiTransform UBiDiTransform;

/**
 * Performs transformation of text from the bidi layout defined by the input
 * ordering scheme to the bidi layout defined by the output ordering scheme,
 * and applies character mirroring and Arabic shaping operations.
 * In terms of <code>UBiDi</code>, such a transformation implies:
 * <ul>
 * <li>calling <code>ubidi_setReorderingMode</code> as needed (when the
 * reordering mode is other than normal),</li>
 * <li>calling <code>ubidi_setInverse</code> as needed (when text should be
 * transformed from a visual to a logical form),</li>
 * <li>resolving embedding levels of each character in the input text by
 * calling <code>ubidi_setPara</code>,</li>
 * <li>reordering the characters based on the computed embedding levels, also
 * performing character mirroring as needed, and streaming the result to the
 * output, by calling <code>ubidi_writeReordered</code>,</li>
 * <li>performing Arabic digit and letter shaping on the output text by calling
 * <code>u_shapeArabic</code>.</li>
 * </ul>
 * An "ordering scheme" encompasses the base direction and the order of text,
 * and these characteristics must be defined by the caller for both input and
 * output explicitly .
 * There are 36 possible combinations of <input, output> ordering schemes,
 * which are partially supported by <code>UBiDi</code> already. Examples of the
 * currently supported combinations:
 * <ul>
 * <li><Logical LTR, Visual LTR>: this is equivalent to calling
 * <code>ubidi_setPara</code> with <code>paraLevel == UBIDI_LTR</code>,</li>
 * <li><Logical RTL, Visual LTR>: this is equivalent to calling
 * <code>ubidi_setPara</code> with <code>paraLevel == UBIDI_RTL</code>,</li>
 * <li><Logical Default ("Auto") LTR, Visual LTR>: this is equivalent to
 * calling <code>ubidi_setPara</code> with
 * <code>paraLevel == UBIDI_DEFAULT_LTR</code>,</li>
 * <li><Logical Default ("Auto") RTL, Visual LTR>: this is equivalent to
 * calling <code>ubidi_setPara</code> with
 * <code>paraLevel == UBIDI_DEFAULT_RTL</code>,</li>
 * <li><Visual LTR, Logical LTR>: this is equivalent to
 * calling <code>ubidi_setInverse(UBiDi*, TRUE)</code> and then
 * <code>ubidi_setPara</code> with <code>paraLevel == UBIDI_LTR</code>,</li>
 * <li><Visual LTR, Logical RTL>: this is equivalent to
 * calling <code>ubidi_setInverse(UBiDi*, TRUE)</code> and then
 * <code>ubidi_setPara</code> with <code>paraLevel == UBIDI_RTL</code>.</li>
 * </ul>
 * All combinations that involve the Visual RTL scheme are unsupported by
 * <code>UBiDi</code>, for instance:
 * <ul>
 * <li><Logical LTR, Visual RTL>,</li>
 * <li><Visual RTL, Logical RTL>.</li>
 * </ul>
 * Example of usage of the transformation engine: 
 * <pre>
 * \code
 * UChar text1[] = {'a', 'b', 'c', 0x0625, '1', 0};
 * UChar text2[] = {'a', 'b', 'c', 0x0625, '1', 0};
 * UErrorCode errorCode = U_ZERO_ERROR;
 * // Run a transformation.
 * ubiditransform_transform(pBidiTransform,
 * text1, -1, text2, -1,
 * UBIDI_LTR, UBIDI_VISUAL,
 * UBIDI_RTL, UBIDI_LOGICAL,
 * UBIDI_MIRRORING_OFF,
 * U_SHAPE_DIGITS_AN2EN | U_SHAPE_DIGIT_TYPE_AN_EXTENDED,
 * &errorCode);
 * // Do something with text2.
 * text2[4] = '2';
 * // Run a reverse transformation.
 * ubiditransform_transform(pBidiTransform,
 * text2, -1, text1, -1,
 * UBIDI_RTL, UBIDI_LOGICAL,
 * UBIDI_LTR, UBIDI_VISUAL,
 * UBIDI_MIRRORING_OFF,
 * U_SHAPE_DIGITS_EN2AN | U_SHAPE_DIGIT_TYPE_AN_EXTENDED,
 * &errorCode);
 *\endcode
 * </pre>
 * 
 *
 * @param pBiDiTransform A pointer to a <code>UBiDiTransform</code> object
 * allocated with <code>ubiditransform_open()</code> or
 * <code>NULL</code>.
 * This object serves for one-time setup to amortize initialization
 * overheads. Use of this object is not thread-safe. All other threads
 * should allocate a new <code>UBiDiTransform</code> object by calling
 * <code>ubiditransform_open()</code> before using it. Alternatively,
 * a caller can set this parameter to <code>NULL</code>, in which case
 * the object will be allocated by the engine on the fly.
 * @param src A pointer to the text that the Bidi layout transformations will
 * be performed on.
 * Note: the text must be (at least)
 * <code>srcLength</code> long.
 * @param srcLength The length of the text, in number of UChars. If
 * <code>length == -1</code> then the text must be zero-terminated.
 * @param dest A pointer to where the processed text is to be copied.
 * @param destSize The size of the <code>dest</code> buffer, in number of
 * UChars. If the <code>U_SHAPE_LETTERS_UNSHAPE</code> option is set,
 * then the destination length could be as large as
 * <code>srcLength * 2</code>. Otherwise, the destination length will
 * not exceed <code>srcLength</code>. If the caller reserves the last
 * position for zero-termination, it should be excluded from
 * <code>destSize</code>.
 * <code>destSize == -1</code> is allowed and makes sense when
 * <code>dest</code> was holds some meaningful value, e.g. that of
 * <code>src</code>. In this case <code>dest</code> must be
 * zero-terminated.
 * @param inParaLevel A base embedding level of the input as defined in
 * <code>ubidi_setPara</code> documentation for the
 * <code>paraLevel</code> parameter.
 * @param inOrder An order of the input, which can be one of the
 * <code>UBiDiOrder</code> values.
 * @param outParaLevel A base embedding level of the output as defined in
 * <code>ubidi_setPara</code> documentation for the
 * <code>paraLevel</code> parameter.
 * @param outOrder An order of the output, which can be one of the
 * <code>UBiDiOrder</code> values.
 * @param doMirroring Indicates whether or not to perform character mirroring,
 * and can accept one of the <code>UBiDiMirroring</code> values.
 * @param shapingOptions Arabic digit and letter shaping options defined in the
 * ushape.h documentation.
 * Note: Direction indicator options are computed by
 * the transformation engine based on the effective ordering schemes, so
 * user-defined direction indicators will be ignored.
 * @param pErrorCode A pointer to an error code value.
 *
 * @return The destination length, i.e. the number of UChars written to
 * <code>dest</code>. If the transformation fails, the return value
 * will be 0 (and the error code will be written to
 * <code>pErrorCode</code>).
