Need location of image for preference pane "PREF" icon I have a stack in my Dock with aliases to my most-used preference panes. In the past, the icons that appear in the grid when I click on the stack have been the large descriptive icons shown in Finder. Since upgrading to Lion, instead, I'm getting new icons. The descriptive icon is small, surrounded by a gear, and the word PREF is under it. At a glance, it's no longer possible to tell which preference pane is which.

Finder doesn't show these large "gear/PREF" icons; the stack and QuickLook do.

Where might I find the image for this icon so I can start figuring out how to replace it? It's nowhere inside the packages for the individual preference panes, System Preferences.app, or Dock.app.
You lift the the icon of any prefpane by the "get info trick"

Also I'm seeing icons in the prefpane bundles in Contents/Resource/xxxx.icns
