+// (1) variable row heights during live resizes
+// HBQueueOutlineView exists solely to get around a bug in variable row height outline
+// views in which row heights get messed up during live resizes. See this discussion:
+// http://lists.apple.com/archives/cocoa-dev/2005/Oct/msg00871.html
+// However, the recommeneded fix (override drawRect:) does not work. Instead, this
+// subclass implements viewDidEndLiveResize in order to recalculate all row heights.
+//
+// (2) prevent expanding of items during drags
+// During dragging operations, we don't want outline items to expand, since a queue
+// doesn't really have children items.
+//
+// (3) generate a drag image that incorporates more than just the first column
+// By default, NSTableView only drags an image of the first column. Change this to
+// drag an image of the queue's icon and desc columns.
