Computes a PangoLogAttr for each character in text. The log_attrs
array must have one PangoLogAttr for each position in text; if
text contains N characters, it has N+1 positions, including the
last position at the end of the text. text should be an entire
paragraph; logical attributes can't be computed without context
(for example you need to see spaces on either side of a word to know
the word is a word).
