Comment 9 for bug 963448

AFAIK the point of this change in Slingshot is to visually link it to the dock and make them stand out of the rest of the desktop.

I believe something like http://ubuntuone.com/7D7C5HqUCd2D9tJqToSm1n will work better than two distinct launchers and that tweak won't be needed, but that's L+1 item obviously.

If Slingshot transparency can't be implemented for Luna, I'd rather fall back to a dock theme that's consistent with Wingpanel.
