* BACKPORTED FROM 8.4 (HEAD) BRANCH:

	* tests/button.test:
	* generic/tkButton.c: Added -activeforeground, -activebackground
	for labels, for the -state option.

	* doc/label.n: Added -disabledforeground to list of options [Bug:
	6053].

	* tests/focus.test (focusSetupAlt): removed wm withdraw from proc
	as it would cause a hang for tkwait visibility

	* tests/menu.test:
	* generic/tk3d.c:
	* generic/tkColor.c:
	* generic/tkCursor.c: corrected handling of 3DBorder, Cursor and
	Color objects on multiple screens. [Bug: 5454]

	* generic/tkCursor.c: Added initialization for nextPtr field of
	TkCursor, patch from Nijtmans/Howlett.

	* canvas.test: added test for 5783.
	* generic/tkCanvPoly.c (DisplayPolygon): added checks for the
	polygon fillGC not being empty to prevent segfault. [Bug: 5783]

	* generic/tkImgGIF.c: Applied patch from Jan Nijtmans to fix a
	problem with the GIF writing code [Bug:	5823].
	* generic/tkImgGIF.c: Changed defines for GIF87a/GIF89a to be
	static char arrays with integer initialization, to address EBCIDIC
	vs. ASCII encoding issues and to handle compilers that don't deal
	with "\xAB" syntax for specifying hex values in strings.

	* generic/tkMenu.c (DeleteMenuCloneEntries): Applied fix from
	[Bug: 5275], which corrected a segfault-causing indexing problem
	when deleting entries from torn-off menus.

	* generic/tkPlace.c (Tk_PlaceCmd): reworked place master/slave
	table init'n to prevent seg fault when using place on multiple
	displays.

	* tests/text.test: Added tests for -regexp -nocase searches with
	backslash character classes.
	* tests/text.test: Added tests for searching when text is elided.
	* generic/tkText.c (TextSearchCmd): Text search did not work
	properly when -regexp and -nocase were used, in combination with
	backslash character classes represented by capital letters (ie,
	\W, \M); altered implementation of -regexp -nocase searches to use
	new regexp interfaces to fix this problem.  [Bug: 5988].
	* generic/tkText.c (TextSearchCmd): Text search was not returning
	the correct index when the search covered (but did not search)
	elided characters; corrected this by adjusting the match index by
	the number of elided characters preceeding the start of the match,
	just as is done with embedded windows, etc. [Bug: 5470].
	* generic/tkText.c (TextSearchCmd): Added a test for a NULL
	segment pointer when doing backwards searches for "" on an empty
	text widget. [Bug: 6007].

	* library/focus.tcl: fixed calling of takeFocus proc [Bug: 5372]

	* win/tkWinMenu.c (ReconfigureWindowsMenu): Added MF_GRAYED bit
	for disabled menu entries, to ensure that those which are drawn by
	the system are shown grayed (such as entries on menubars) [Bug: 4372].
	* win/tkWinMenu.c (ReconfigureWindowsMenu): Added code to add the
	MF_SEPARATOR bit for SEPARATOR_ENTRY menu items.  This causes
	separator entries on the system menu to be drawn correctly [Bug: 5451].
	* win/tkWinMenu.c (GetMenuSeparatorGeometry): Tweaked height
	requested for separator bars to be (linespace - (2*descent))
	instead of just (linespace); this makes the separator occupy a
	more correct amount of vertical space. [Bug: 5303].
