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 node not found in the tree, 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 returned rectangle is equivalent to the background_area
passed to render. These background areas tile to cover the
entire bin window. Contrast with the cell_area, returned by
get_cell_area, which returns only the cell itself, excluding surrounding borders and the tree expander area.
