When a preferred density is specified, prune all but the closest matching density when the exact density resource does not exist. If a preferred density resource does not exist and a higher density resource exists, prune all but the resource with the next highest density relative to the preferred density. If a preferred density resource does not exist and there is no higher density resource, prune all but the resource with the next lowest density relative to the preferred density. bug:11224465 Change-Id: I99b3950fe3d8116a5625968ed383442315ae8526
