The bounding rectangle of the receiver.
The view that manages the cell.
An array of
NSDragging objects representing the cell.
The default implementation generates an image from the cell and return two components: one for
label and another for
icon. This is done by capturing the portion from the
image methods respectively.
This method can be subclassed and overridden to provide a custom set of
NSDragging to create the drag image for the cell. This method is generally used by NSTableView/NSOutlineView.
