/**
* pango_glyph_string_get_logical_widths:
* @glyphs: a #PangoGlyphString
* @text: the text corresponding to the glyphs
* @length: the length of @text, in bytes
* @embedding_level: the embedding level of the string
* @logical_widths: an array whose length is the number of characters in
* text (equal to g_utf8_strlen (text, length) unless
* text has NUL bytes)
* to be filled in with the resulting character widths.
*
* Given a #PangoGlyphString resulting from pango_shape() and the corresponding
* text, determine the screen width corresponding to each character. When
* multiple characters compose a single cluster, the width of the entire
* cluster is divided equally among the characters.
*
* See also pango_glyph_item_get_logical_widths().
