-- The @PangoGlyphGeometry@ structure contains width and positioning
-- information for a single glyph.
-- 
-- Note that /@width@/ is not guaranteed to be the same as the glyph
-- extents. Kerning and other positioning applied during shaping will
-- affect both the /@width@/ and the /@xOffset@/ for the glyphs in the
-- glyph string that results from shaping.
-- 
-- The information in this struct is intended for rendering the glyphs,
-- as follows:
-- 
-- 1. Assume the current point is (x, y)
-- 2. Render the current glyph at (x + x_offset, y + y_offset),
-- 3. Advance the current point to (x + width, y)
-- 4. Render the next glyph
