        Maps a <b>texture</b> onto triangles being built
        from <b>vertices</b> according to the chosen <b>formation</b>.
 </P><P>
        Optional <b>indices</b> can be used to avoid rearrangement of vertex lists,
        otherwise the vertex list is processed consecutively, i.e. as if <b>indices</b>
        are ascending numbers starting at zero.
 </P><P>
        Either the number of <b>indices</b> (if non NULL) or the number of <b>vertices</b> is
        specified by <b>num</b> and has to be three at least. If the chosen <b>formation</b>
        is DTTF_LIST it also has to be a multiple of three.
</P>
