Array containing 0-based indices of words' first chars into the "text" string. If the "p" array is null or empty, this array must also be null or empty. If the "p" array is not empty, and this array has exactly one element "-1", the "p" array is assumed to contain coordinates of all individual chars in "text". In all other cases, this array must have the same number of elements as the "p" array, and must contain indices into "text" string of subsequent words' first chars. In that case the first element of this array must contain "0" (index of the first char of the first word in the text run). The length of a word is determined by the starting indices of that and next word.
