[<code><a rd-options="" href="/link/PangoRectangle?package=RGtk2&version=2.20.31" data-mini-rdoc="RGtk2::PangoRectangle">PangoRectangle</a></code>]  rectangle in which to store the position of the grapheme

<code>pos</code>

Converts from an index within a <code><a rd-options="" href="/link/PangoLayout?package=RGtk2&version=2.20.31" data-mini-rdoc="RGtk2::PangoLayout">PangoLayout</a></code> to the onscreen position
corresponding to the grapheme at that index, which is represented
as rectangle.  Note that <code>pos->x</code> is always the leading
edge of the grapheme and <code>pos->x + pos->width</code> the trailing
edge of the grapheme. If the directionality of the grapheme is right-to-left,
then <code>pos->width</code> will be negative.
