     Moves the alignments of 'tree.view' to the position specified by
     'column' and 'path'.  If 'column' is 'NULL', then no horizontal
     scrolling occurs.  Likewise, if 'path' is 'NULL' no vertical
     scrolling occurs.  At a minimum, one of 'column' or 'path' need to
     be non-'NULL'.  'row.align' determines where the row is placed,
     and 'col.align' determines where 'column' is placed.  Both are
     expected to be between 0.0 and 1.0. 0.0 means left/top alignment,
     1.0 means right/bottom alignment, 0.5 means center.

_U_s_a_g_e:

     gtkTreeViewScrollToCell(object, path, column = NULL, use.align = FALSE, row.align = 0, col.align = 0)

_A_r_g_u_m_e_n_t_s:

'object': ['GtkTreeView']  A 'GtkTreeView'.

  'path': ['GtkTreePath']  The path of the row to move to, or 'NULL'.

'column': ['GtkTreeViewColumn']  The 'GtkTreeViewColumn' to move
          horizontally to, or 'NULL'.

'use.align': [logical]  whether to use alignment arguments, or 'FALSE'.

'row.align': [numeric]  The vertical alignment of the row specified by
          'path'.

'col.align': [numeric]  The horizontal alignment of the column
          specified by 'column'.

_D_e_t_a_i_l_s:

     If 'use.align' is 'FALSE', then the alignment arguments are
     ignored, and the tree does the minimum amount of work to scroll
     the cell onto the screen. This means that the cell will be
     scrolled to the edge closest to its current position.  If the cell
     is currently visible on the screen, nothing is done.

     This function only works if the model is set, and 'path' is a
     valid row on the model.  If the model changes before the
     'tree.view' is realized, the centered path will be modified to
     reflect this change.
