                                            int row,
                                            int depth,
                                            boolean expanded,
                                            Rectangle bounds)

Returns, by reference in bounds, the size and x origin to place value at. The calling method is responsible for determining the Y location. If bounds is null, a newly created Rectangle should be returned, otherwise the value should be placed in bounds and returned.

Parameters:
value - the value to be represented
row - row being queried
depth - the depth of the row
expanded - true if row is expanded, false otherwise
bounds - a Rectangle containing the size needed to represent value
Returns:
a Rectangle containing the node dimensions, or null if node has no dimension
