Given a segment of text and the corresponding pango.analysis.Analysis structure
returned from funcPango.itemize, convert the characters into glyphs. You
may also pass in only a substring of the item from funcPango.itemize.
It is recommended that you use funcPango.shape_full instead, since
that API allows for shaping interaction happening across text item
boundaries.
Some aspects of hyphen insertion and text transformation (in particular,
capitalization) require log attrs, and thus can only be handled by
funcPango.shape_item.
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 need to subtract the item offset from their indices before
calling funcPango.shape.
