\brief Computes closest polygon of the convex hull geometry for a given impact point
and impact direction. When doing sweeps against a scene, one might want to delay
the rather expensive computation of the hit face index for convexes until it is clear
the information is really needed and then use this method to get the corresponding
face index.
\param[in] convexGeom The convex mesh geometry.
\param[in] geomPose Pose for the geometry object.
\param[in] impactPos Impact position.
\param[in] unitDir Normalized impact direction.
\return Closest face index of the convex geometry.
