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
