[NEW] Start restoring compatiblity with 10.4.
This builds and works under 10.5, and works under 10.4 - except for a crash in -mouseDown (Symbol not found: _objc_assign_weak). The code also builds under 10.4, with a couple of tweaks, and does not crash in this case, but also is missing some features and will not build universal for some reason. (Michael Baltaks)
