xcode4 - What do these Xcode 4 debugger icons mean?

Question

I haven't been able to find what these Xcode icons mean. Some you can deduce (cup icon is cocoa, person icon is your code) but other's are more mysterious.

UPDATE 1:

I was able to find the icon files under:

.../Xcode.app/Contents/PlugIns/DebuggerFoundation.ideplugin/Contents/Resources

There's a total of 13 different icons and they are all clearly labeled. In the screenshot that I posted we have:

• Person icon is User
• Mug icon is AppKit (or UIKit)
• Briefcase icon is Frameworks
• Gear icon is System
• Morse code icon is Foundation
• Spider web looking icon is Web

Update 2:

A while back I wrote a blog post that's easier to read: http://jlmendezbonini.com/2013/03/27/Xcode-4-debugger-icons.html

Update 3:

Looks like Apple finally documented it in the Process View Display section. Here's a link to the image:

Answer 1

Here's a quick screen shot of the folder mentioned. The names explain the meaning of each icon. This is from xcode 5 beta 2.
