Render a <link linkend="PangoLayout"><type>PangoLayout</type></link> onto a FreeType2 bitmap, with he
location specified in fixed-point Pango units rather than
pixels. (Using this will avoid extra inaccuracies from
rounding to integer pixels multiple times, even if the
final glyph positions are integers.)</para>
