Scrolls the tree view such that the top-left corner of the visible
area is @tree_x, @tree_y, where @tree_x and @tree_y are specified
in tree coordinates. The @tree_view must be realized before
this function is called. If it isn't, you probably want to be
using gtk_tree_view_scroll_to_cell().
If either @tree_x or @tree_y are -1, then that direction isn’t scrolled.
