Fills the bounding rectangle in bin_window coordinates for the cell at the
row specified by path and the column specified by column. If path is
NULL, or points to a path not currently displayed, the y and height fields
of the rectangle will be filled with 0. If column is NULL, the x and width
fields will be filled with 0. The sum of all cell rects does not cover the
entire tree; there are extra pixels in between rows, for example. The
returned rectangle is equivalent to the cell_area passed to
CellRenderer.render. This function is only valid if tree_view is
realized.
