 * @brief Initializes the gradient array.
 *
 * If the implementation requires a bigger array, it must return the number of required bytes.
 *
 * The position array may be null; in that case, a linear distribution is set.
 *
 * @param[in] gradient: the array to initialize
 * @param[in] length: the array size
 * @param[in] colors: the colors to store
 * @param[in] count: the available number of colors
 * @param[in] positions: the colors positions or null to set default positions.
 * @param[in] xStart: the x-coordinate for the start of the gradient vector
 * @param[in] yStart: the y-coordinate for the start of the gradient vector
 * @param[in] xEnd: the x-coordinate for the end of the gradient vector
 * @param[in] yEnd: the y-coordinate for the end of the gradient vector
 *
 * @return LLVG_SUCCESS on success or a value that indicates the minimal required size of the array.
