Preload only visible thumbnails and task icons. (Bug 17672056, Bug 18291345) This change ensures that only the number of visible thumbnails and task icons are loaded to minimize the delay required when initializing the stack without the cache. In addition, this change reduces the number of times that the task stack is recomposed when launching recents (in addition to the number of calls to getRecentTasks()). There is also a fix to a regression where the exit trigger is not run when the task stack view is empty. Change-Id: I75834ff3c57c0e5dad6252b982f71c6e740071f2
