Set Size to the Positional Extent of a Previous Gadget

A new gadget's size component can be specified as the distance from its placement position co-ordinate to the Positional Extent of another gadget (MINimum, CENtre or MAXimum), for example:

frame .fr2 |Frame 2| at ymax.fr1 Width To min.fr1 Height To cen

frame .fr3 |Frame 3| at ymax.fr2 Width To max.fr1 Height To max Form

The width of fr2 extends from its implied X-position (XMIN of last placed gadget) to the minimum X-position of gadget fr1. Its height extends from its specified Y-position (YMAX of fr1) to the center position of the most recently defined gadget.
