/**
* 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`.
