3261 
    * The values of $col_start and $row_start are passed in from the calling

3264

3272

3273 
    *       Where:  X is distance from the left side of the underlying cell
3274 
    *               Y is distance from the top of the underlying cell
3275 
    *               W is the width of the cell
