This slider selects the proportion of shapes in the designs that you want to be of this zoneType. If you select "Proportionate", then this zoneType will want to appear a number of times appropriate to the number of shapes in the design and the number of zoneTypes that are defined. If you select "All", then this zoneType will desire to be all of the shapes in the designs. Note that if there is more than one zoneType that desires to be all of the shapes in the design then there is an inherent conflict of interest, and it may yield an interesting evolutionary tension. If you select "None", then this zoneType will desire not to be present at all in the designs. You can, of course, select any value in between these extremes.
