For what Bayon is using NSTrackingArea, see ImagePreviewCell class in
Apple's sample PhotoSearch. From what I remember, it's exclusively
used in that place. It's currently available on this URL:

For those interested in NSTrackingArea and too lazy to look it up:

Precisely because it's used in such basic sample code I suspect it's
going to be used in a lot of post-10.5 OS X code. Also, based on the
following link, and looking quickly at GNUstep source code, it looks
like we can rename the private GSTrackingRect class (possibly adding
a
same-named subclass, for compatibility).

The real deal here is probably supporting correctly all the flags
passed in NSTrackingAreaOptions.
And then:
* NSRunLoopCommonModes shouldn't be that hard, given that
gnustep-corebase supports it already. BTW, Apple's documentation in this
case is quite weak, it reminds me of ALSA.
* "Common File System Resource Keys" in NSURL can't be to difficult, I
could try to add it myself.
* Grand Central Dispatch - I've successfully compiled
https://github.com/nickhutchinson/libdispatch/ with a few changes to
make use of libobjc2's Blocks support. Wouldn't it we worthwhile to move
objc/blocks_runtime.h and objc/blocks_private.h to a more OS X-like
location/naming "Block_private.h"/"Block.h"? Symlinks would work too...
With that and a working NIB loader, we could get it to work finally.
