pango.Shape(text$, analysis, glyphs)

Given a segment of text and the corresponding Pango analysis structure returned from pcontext:Itemize(), convert the characters into glyphs. You may also pass in only a substring of the item from pcontext:Itemize().

It is recommended that you use pango.ShapeFull() instead, since that API allows for shaping interaction happening across text item boundaries.

Note that the extra attributes in the analyis that is returned from pcontext:Itemize() have indices that are relative to the entire paragraph, so you need to subtract the item offset from their indices before calling this function.
