/**
 * 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`.
