Hmm, I was considering using this to create top-level dialogs in Windows Aura
with the Windows Classic theme (no Aero DWM Glass), as the pictures in comments
#3 and #4 at http://crbug.com/323278#c3 (I had to revert to the old style for
the hung renderer dialog). But since I'm not sure I'll end up using this, I
guess you can remove it for now.
