Draws the glyphs in glyph_item with the specified PangoRenderer,
embedding the text associated with the glyphs in the output if the
output format supports it (PDF for example).
Note that text is the start of the text for layout, which is then
indexed by glyph_item->item->offset.
If text is NULL, this simply calls pango_renderer_draw_glyphs().
The default implementation of this method simply falls back to
pango_renderer_draw_glyphs().
