target:  Calculate the requirements for the minor axis.  This is called by the superclass whenever the requirements need to be updated (i.e. a preferenceChanged was messaged through this view). <p> This is implemented to calculate the requirements as the sum of the requirements of the columns and then adjust it if the CSS width or height attribute is specified and applicable to the axis.
