A DESCRIPTION OF THE REQUEST :
Currently, setRowHeight(int) and setRowHeight(int, int) throw an IllegalArgumentException if the row height is less than 1. However, we need to be able to set the row height to 0.

JUSTIFICATION :
In our use of the JTable we have a need to hide the row but still have
the data contained in the row available for calculation purposes. The
simplest way to do this is by setting the row height to zero.
