*** macosx-8-4-branch merged into the mainline [tcl patch #602770] ***macosx_8_4_merge_2002_08_31_trunk

	* generic/tk.decls:
	* generic/tkInt.decls: added new "aqua" specific entries to the
	stubs tables. Changed all "unix" entries to "x11" to allow us to
	distinguish and build both "aqua" on MacOSX and "x11" on MacOSX.

	* generic/tk.h: added a #ifnded RESOURCE_INCLUDED so that tk.h can
	be passed to the resource compiler.

	* generic/tkCmds.c (Tk_TkObjCmd): added [tk windowingsystem]
	subcommand: returns "x11" when running on X11, "win32" on Windows,
	"classic" on MacOS9 and "aqua" on MacOSX Aqua (i.e. Carbon)

	* generic/tkFont.c (TkFontGetFirstTextLayout): new private function
	returning the first chunk of a Tk_TextLayout, i.e. until the first
	font change on the first line (or the whole first line if there is
	no such font change).

	* generic/tkMain.c: made Tcl_ThreadDataKey static

	* library/demos/puzzle.tcl: fixed button metrics for aqua

	* tests/cursor.test: check for presence of arrow cursor instead of
	heart cursor

	* xlib/xcolors.c: changed xColors static initialization to more
	standard C

	* macosx/Wish.pbproj/jingham.pbxuser (new):
	* macosx/Wish.pbproj/project.pbxproj (new): project for Apple's
	ProjectBuilder IDE.

	* macosx/Makefile (new): simple makefile for building the project
	from the command line via the ProjectBuilder tool 'pbxbuild'.

	* macosx/tkMacOSXAppInit.c (new): macosx specific AppInit looking
	for a AppMain.tcl file in its bundled Resources/Scripts folder. If
	present, argv[1] is set to that file and the Scripts folder is
	added to the auto_path. This allows tk apps to embed scripts within
	their bundle directory structure.

	* macosx/tkMacOSXInit.c (new): macosx adapted version of
	tkUnixInit.c: we initialize & cache the Carbon native encoding
	(e.g. 'macRoman') and try to find the tk script library files
	inside Tk packaged as a framework.

	* macosx/tkMacOSXNotify.c (new): new macosx specific merged
	Carbon/select-based notifier.

	* macosx/tkMacOSXEvent.c (new):
	* macosx/tkMacOSXEvent.h (new):
	* macosx/tkMacOSXKeyEvent.c (new):

	handling functionality.

	implementation in tk/mac.

	implemented currently.

	* macosx/tkMacOSXDebug.h (new):

	debugging MacOS events, regions, etc.
