 OS X has one, too. Used during drag & drop, I think.

 This sounds like a job for IconKit. In MacOS 9, you could have 
different "icon transforms" applied to an icon. Those included 
"selected" and "open". "selected" was just darkened, and "open" was the 
icon's opaque area filled with a dark bluish-grey and outlined, so it 
looked like a hole.

 Would probably be a smart idea to have such "transforms" in IconKit as 
well (don't forget combinations of those). If a theme provides "open" or 
"selected" variants of its icons, those are used, otherwise a transform 
is applied to them.

 Note that on MacOS X, all this stuff is only available via Carbon. 
Which means while an IconKit version for MacOS X would be possible (and 
I think there's a third-party "icon suite" wrapper class around the 
Carbon stuff), there is no Cocoa API one could be compatible to -- yet.
