-		A DirectionalLight is a type of [Light] node that emits light constantly in one direction (the negative z axis of the node). It is used lights with strong intensity that are located far away from the scene to model sunlight or moonlight. The worldspace location of the DirectionalLight transform (origin) is ignored, only the basis is used do determine light direction.

It is used for lights with strong intensity that are located far away from the scene to model sunlight or moonlight. The worldspace location of the DirectionalLight transform (origin) is ignored. Only the basis is used do determine light direction.

+ *
+ *              For OFB, you must set up the context with
+ *              mbedtls_aes_setkey_enc(), regardless of whether you are
+ *              performing an encryption or decryption operation. This is
+ *              because OFB mode uses the same key schedule for encryption and
+ *              decryption.
+ *
+ *              The OFB operation is identical for encryption or decryption,
+ *              therefore no operation mode needs to be specified.
+ *
+ * \note        Upon exit, the content of iv, the Initialisation Vector, is
+ *              updated so that you can call the same function again on the next
+ *              block(s) of data and get the same result as if it was encrypted
+ *              in one call. This allows a "streaming" usage, by initialising
+ *              iv_off to 0 before the first call, and preserving its value
+ *              between calls.
+ *
+ *              For non-streaming use, the iv should be initialised on each call
+ *              to a unique value, and iv_off set to 0 on each call.
+ *
+ *              If you need to retain the contents of the initialisation vector,
+ *              you must either save it manually or use the cipher module
+ *              instead.
+ *
+ * \warning     For the OFB mode, the initialisation vector must be unique
+ *              every encryption operation. Reuse of an initialisation vector
+ *              will compromise security.
+ *
+ * \param ctx      The AES context to use for encryption or decryption.
+ * \param length   The length of the input data.
+ * \param iv_off   The offset in IV (updated after use).
+ * \param iv       The initialization vector (updated after use).

+ *
+ * The platform lacks support for 32x32 -> 64-bit multiplication.
+ *
+ * Used in:
+ *      library/poly1305.c
+ *
+ * Some parts of the library may use multiplication of two unsigned 32-bit
+ * operands with a 64-bit result in order to speed up computations. On some
+ * platforms, this is not available in hardware and has to be implemented in
+ * software, usually in a library provided by the toolchain.
+ *
+ * Sometimes it is not desirable to have to link to that library. This option
+ * removes the dependency of that library on platforms that lack a hardware
+ * 64-bit multiplier by embedding a software implementation in Mbed TLS.
+ *
+ * Note that depending on the compiler, this may decrease performance compared
+ * to using the library function provided by the toolchain.

+ * \brief           Callback type: start external signature operation.
+ *
+ *                  This callback is called during an SSL handshake to start
+ *                  a signature decryption operation using an
+ *                  external processor. The parameter \p cert contains
+ *                  the public key; it is up to the callback function to
+ *                  determine how to access the associated private key.
+ *
+ *                  This function typically sends or enqueues a request, and
+ *                  does not wait for the operation to complete. This allows
+ *                  the handshake step to be non-blocking.
+ *
+ *                  The parameters \p ssl and \p cert are guaranteed to remain
+ *                  valid throughout the handshake. On the other hand, this
+ *                  function must save the contents of \p hash if the value
+ *                  is needed for later processing, because the \p hash buffer
+ *                  is no longer valid after this function returns.
+ *
+ *                  This function may call mbedtls_ssl_set_async_operation_data()
+ *                  to store an operation context for later retrieval
+ *                  by the resume or cancel callback.
+ *
+ * \note            For RSA signatures, this function must produce output
+ *                  that is consistent with PKCS#1 v1.5 in the same way as
+ *                  mbedtls_rsa_pkcs1_sign(). Before the private key operation,
+ *                  apply the padding steps described in RFC 8017, section 9.2
+ *                  "EMSA-PKCS1-v1_5" as follows.
+ *                  - If \p md_alg is #MBEDTLS_MD_NONE, apply the PKCS#1 v1.5
+ *                    encoding, treating \p hash as the DigestInfo to be
+ *                    padded. In other words, apply EMSA-PKCS1-v1_5 starting
+ *                    from step 3, with `T = hash` and `tLen = hash_len`.
+ *                  - If `md_alg != MBEDTLS_MD_NONE`, apply the PKCS#1 v1.5
+ *                    encoding, treating \p hash as the hash to be encoded and
+ *                    padded. In other words, apply EMSA-PKCS1-v1_5 starting
+ *                    from step 2, with `digestAlgorithm` obtained by calling
+ *                    mbedtls_oid_get_oid_by_md() on \p md_alg.
+ *
+ * \note            For ECDSA signatures, the output format is the DER encoding
+ *                  `Ecdsa-Sig-Value` defined in
+ *                  [RFC 4492 section 5.4](https://tools.ietf.org/html/rfc4492#section-5.4).

+ * \param ssl             The SSL connection instance. It should not be

+ *
+ *                  This function typically checks the status of a pending
+ *                  request or causes the request queue to make progress, and
+ *                  does not wait for the operation to complete. This allows
+ *                  the handshake step to be non-blocking.
+ *
+ *                  This function may call mbedtls_ssl_get_async_operation_data()
+ *                  to retrieve an operation context set by the start callback.
+ *                  It may call mbedtls_ssl_set_async_operation_data() to modify
+ *                  this context.
+ *
+ *                  Note that when this function returns a status other than
+ *                  #MBEDTLS_ERR_SSL_ASYNC_IN_PROGRESS, it must free any
