Summary:
Using a QLPreviewView in a view hierarchy that is layer-backed doesn't display some types of files.

Steps to Reproduce:
1) Make a view hierarchy that is layer-backed, and contains a QLPreviewView.
2) Set a that view's previewItem to a txt, rtf, doc, xls, or ppt file.


Expected Results:
The QLPreviewView should show a QuickLook preview of that file.


Actual Results:
The QLPreviewView is just an empty, white rectangle.


Notes:
Making the view hierarchy not be layer-backed makes it work fine.
