/**
* PangoGlyphItem:
* @item: corresponding `PangoItem`
* @glyphs: corresponding `PangoGlyphString`
* @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 `PangoGlyphItem` is a pair of a `PangoItem` and the glyphs
* resulting from shaping the items text.
*
* As an example of the usage of `PangoGlyphItem`, the results
* of shaping text with `PangoLayout` is a list of `PangoLine`,
* each of which contains a list of `PangoGlyphItem`.
