+/**
+ * Pango2GlyphItem:
+ * @item: corresponding `Pango2Item`
+ * @glyphs: corresponding `Pango2GlyphString`
+ * @y_offset: shift of the baseline, relative to the baseline
+ *   of the containing line. Positive values shift upwards
+ * @start_x_offset: horizontal displacement to apply before the
+ *   glyph item. Positive values shift right
+ * @end_x_offset: horizontal displacement to apply after th
+ *   glyph item. Positive values shift right
+ *
+ * A `Pango2GlyphItem` is a pair of a `Pango2Item` and the glyphs
+ * resulting from shaping the items text.
+ *
+ * As an example of the usage of `Pango2GlyphItem`, the results
+ * of shaping text with `Pango2Layout` is a list of `Pango2Line`,
+ * each of which contains a list of `Pango2GlyphItem`.
