This is similar to funcPango.shape_with_flags, except it takes a
pango.item.Item instead of separate item_text and analysis arguments.
It also takes log_attrs, which are needed for implementing some aspects
of hyphen insertion and text transforms (in particular, capitalization).
Note that the extra attributes in the analyis that is returned from
funcPango.itemize have indices that are relative to the entire paragraph,
so you do not pass the full paragraph text as paragraph_text, you need
to subtract the item offset from their indices before calling
funcPango.shape_with_flags.
Convert the characters in item into glyphs.
