If the Folder is not closed on on the first page, we animate the
current page items as if they are in the preview.
When the Folder finishes closing, the first page preview items
slide in as the current page preview items slide out.

Before, with the FolderIconPreviewVerifier, we would
adjust which items are displayed in the FolderIcon.
This caused some issues where the apps in the folder
icon would jump to whatever was in the upper left quadrant.
Now, we always display the 4 first items in the icon by
modifying the XY positions of the items within the Folder.

This class verifies whether an item in a Foder is displayed in
the FolderIcon preview, based on the item's rank.
We use this class to determine which items in a Folder will be
displayed in the preview.
