/*! \brief Draw a line on screen.
* \par Function Description
* This function is used to draw a line on screen. The line is described
* in the object which is referred by <B>o_current</B>. The line is displayed
* according to the current state, described in the GSCHEM_TOPLEVEL object pointed
* by <B>w_current</B>.
*
* It first checks if the object is valid or not. If not it returns and do
* not output anything. That should never happen though.
*
* \param [in] w_current The GSCHEM_TOPLEVEL object.
* \param [in] o_current The line OBJECT to draw.
