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).
