PlutoResizePushAndPull<T> class

Changes the size of the object to be changed by offset and pushes or pulls the size of the remaining items.

Change the width of the item corresponding to isMainItem by offset. Negative or positive.

items are all siblings that will be affected when the size of the item corresponding to isMainItem is changed.

isMainItem is a callback that should return whether or not the item is subject to resizing.

getItemSize is a callback that should return the size of item.

getItemMinSize is a callback that should return the minimum width of item.

setItemSize is a callback that should change the size of item to size.

update finishes resizing and returns whether or not to change.
