_D_e_s_c_r_i_p_t_i_o_n:

     This function can be used to generate a viewport path for use in
     'downViewport' or 'seekViewport'.

     A viewport path is a list of nested viewport names.

_U_s_a_g_e:

     vpPath(...)

_A_r_g_u_m_e_n_t_s:

     ...: Character values which are viewport names. 

_D_e_t_a_i_l_s:

     Viewport names must only be unique amongst viewports which share
     the same parent in the viewport tree.

     This function can be used to generate a specification for a
     viewport that includes the viewport's parent's name (and the name
     of its parent and so on).

     For interactive use, it is possible to directly specify a path,
     but it is strongly recommended that this function is used
     otherwise in case the path separator is changed in future versions
     of grid.

_V_a_l_u_e:

     A ' vpPath ' object.

     'viewport', 'pushViewport', 'popViewport', 'downViewport',
     'seekViewport', 'upViewport'
