    * @Function:

-   * @Description:
-   *   Checks the size of a buffer and reallocates it if necessary.
-   *
-   * @Input:
-   *   memory ::
-   *     A handle to the parent memory object.
-   *
-   *   multiplier ::
-   *     The size in bytes of each element in the buffer.
-   *
-   *   new_max ::
-   *     The new capacity (size) of the buffer.
-   *
-   * @InOut:
-   *   size ::
-   *     The address of the buffer's current size expressed
-   *     in elements.
-   *
-   *   buff ::
-   *     The address of the buffer base pointer.
-   *
-   * @Return:
-   *   FreeType error code.  0 means success.
