The low level window traps they use are (to the best of my recollection)
documented in IM.  I know this does not guarantee that those traps will be
present in the future but Apple does try to let documented things stand.
As to direct manipulation of window regions, I do not recall any of that 
being done but I could be wrong.

As for licensing fees, there is a note at the bottom of the page in MacTutor
where the source code disks are listed that says in part "the code contained
[on the disks] may be included, if properly acknowledged, in commercially
marketed products at no additional charge to the developer."
