Code review comment for lp:~bilalakhtar/unity/fix-queuedraw-after-addlaunchericon

@Michal: Yes, it doesn't sound right because it's a workaround to an Intel Atom driver bug (see bug #981168). Just move the OnLauncherAddRequestSpecial call to the same place where we're calling QueueDraw right now, and boom, the launcher is broken for all Intel Atom netbooks.
