How do I get back the application icon in the window title?

http://askubuntu.com – I recently installed 12.04 and switched to Gnome-Classic. I am used to the old gnome interface so I wanted to change the window title bar. So far I have moved the title bar buttons to the right but I cant seem to find a way to get back the application icon instead of the little dot for the window menu button. Some themes seem to have this by default, like Bright. But I don't like the other looks of Bright... Why do I want this?! Just because I think it's pretty... (HowTos)
