get_background_area
Description:
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.
