* macosx/tkMacOSXCarbonEvents.c: add window event target carbon event

	* macosx/tkMacOSXEvent.c:	 handler for all kEventClassWindow and
	* macosx/tkMacOSXEvent.h:	 kEventClassMouse events; move all
	* macosx/tkMacOSXNotify.c:	 remaining events except for
	* macosx/tkMacOSXWindowEvent.c:	 kEventClassKeyboard from dispatcher to
	application event handler; pass event handler callRef downstream; fix
	debug event tracing; process all tcl event types in carbon event timer;
	delay carbon event timer first fire; add TkMacOSXTrackingLoop() to mark
	enter/exit of event tracking loop during which all tcl events but only
	carbon update events should be processed by the timer (replaces various
	calls to Tcl_SetServiceMode()); rename TkMacOSXReceiveAndProcessEvent()
	to TkMacOSXReceiveAndDispatchEvent(), move it from tkMacOSXEvent.c to
	tkMacOSXCarbonEvents.c and modify it to dequeue only update events
	during a tracking loop; add TkMacOSXRunTclEventLoop() to standardize
	the various ways in use to run the tcl event loop; add handling of
	kEventClassAppearance events (for ScrollBarVariantChanged event).

	* macosx/tkMacOSXDialog.c:	use new TkMacOSXTrackingLoop() around
	* macosx/tkMacOSXEvent.c:	blocking API that puts up modal dialogs
	* macosx/tkMacOSXMenu.c:	or when entering/exiting menu/control
	* macosx/tkMacOSXMouseEvent.c:	tracking, window dragging and other
	* macosx/tkMacOSXScale.c:	mouse tracking loops.
	* macosx/tkMacOSXScrlbr.c:
	* macosx/tkMacOSXWindowEvent.c:
	* macosx/tkMacOSXWm.c:

	* macosx/tkMacOSXDialog.c:	use new TkMacOSXRunTclEventLoop()
	* macosx/tkMacOSXScale.c:	instead of Tcl_DoOneEvent(),
	* macosx/tkMacOSXScrlbr.c:	Tcl_ServiceAll(), TclServiceIdle()
	* macosx/tkMacOSXWindowEvent.c:	and Tcl_GlobalEval("update idletasks").

	* macosx/tkMacOSXColor.c: make available as Tk system colors all
	* macosx/tkMacOSXPort.h:  appearance manager brushes, text colors and
	backgrounds with new and legacy names, as well as the fully transparent
	color "systemTransparent"; add TkMacOSXSetColorIn{Port,Context}() to
	directly set an X pixel color value in the current QD port resp. the
	given CG context without requiring passage through rgb representation
	(lossy for most system colors); modernize/remove Classic-era code;
	replace crufty strcmp() elseifs by Tcl_GetIndexFromObjStruct().

	* macosx/tkMacOSXButton.c:	use new TkMacOSXSetColorInPort()
	* macosx/tkMacOSXDraw.c:	instead of setting rgb color directly
	* macosx/tkMacOSXMenubutton.c:	to allow for non-rgb system colors.

	* macosx/tkMacOSXCursor.c: implement "none" cursor as on other
	platforms [Patch 1615427]; add all missing appearance manager cursors.

	* macosx/tkMacOSXDefault.h: set SELECT_FG_COLORs to None to match aqua
	L&F; use standard system color names; use new 'menu' system font;
	correct default scrollbar width.

	* macosx/tkMacOSXDraw.c:	standardize initialization, use and
	* macosx/tkMacOSXInt.h:		emptying of various static temp rgns
	* macosx/tkMacOSXRegion.c:	onto two global RgnHandles; in debug
	* macosx/tkMacOSXSubwindows.c:	builds, verify emptiness of these temp
	* macosx/tkMacOSXWindowEvent.c:	rgns before use.

	* macosx/tkMacOSXDraw.c: add TkMacOSX{Setup,Restore}DrawingContext() to
	* macosx/tkMacOSXInt.h:  abstract common setup & teardown of drawing
	environment (for both CG and QD); save/restore QD theme drawing state;
	handle GC clip region; add TkpClipDrawableToRect() to allow clipped
	drawing into drawable regardless of GC used; use new system color
	"systemWindowHeaderBackground" to setup background in themed toplevels;
	correct implementation of TkMacOSXMakeStippleMap().

	* macosx/tkMacOSXEntry.c: use new TkMacOSXSetupDrawingContext() and
	* macosx/tkMacOSXFont.c:  TkMacOSXRestoreDrawingContext() instead of
	various setup/teardown procs like TkMacOSX{SetUp,Release}CGContext(),
	TkMacOSXQuarz{Start,End}Draw(), TkMacOSXSetUpGraphicsPort() etc.

	* macosx/tkMacOSXEmbed.c: add CG context and drawable clip rgn fields
	* macosx/tkMacOSXInt.h:   to MacDrawable struct.
	* macosx/tkMacOSXSubwindows.c:

	* macosx/tkMacOSXDialog.c: make -parent option of tk_getOpenFile et al.
	use the sheet version of NavServices dialogs; ensure native parent win
	exists before using StandardSheet API for tk_messageBox [Bug 1677611];
	force sheets to behave like app-modal dialogs via WindowModality() API;
	use more modern ColorPicker API.

	* macosx/tkAboutDlg.r: use themed movable modal dialog, fix (c) year.

	* macosx/tkMacOSXEntry.c:  take xOff/yOff of MacDrawable into account
	when computing locations/bounds to ensure correct posititioning when
	not drawing into intermediate pixmap.

	* macosx/tkMacOSXFont.c: use appearance manager API to map system font
	* macosx/tkMacOSXFont.h: names to TkFonts; add "menu" system font for
	menu item text drawing from MDEF; disable broken QD stippling.

	* macosx/tkMacOSXMenu.c:		large-scale rewrite of custom
	* macosx/tkMacOSXMenu.r (removed):	MDEF and related code that
	* unix/Makefile.in:			restores many longtime-MIA
	features to working order (e.g. images, custom colors & fonts in menus
	etc); implement compound menu items; use Appearance Mgr and ThemeText
	APIs to mimic native MDEF as closely as possible when default "menu"
	system font is used; remove now obsolete SICN drawing code and
	resources.

	* macosx/tkMacOSXCarbonEvents.c: handle additional menu carbon events
	* macosx/tkMacOSXEvent.c:	 in order to support <<MenuSelect>> in
	* macosx/tkMacOSXMenu.c:	 the menubar and in menus that are not
	* macosx/tkMacOSXMenus.c:	 using the custom MDEF [Bug 1620826];
	fix early and missing clearing of current Tk active menu entry; fix
	extraneous sending of <<MenuSelect>> during active menu entry clearing.

	* macosx/tkMacOSXMouseEvent.c: add support for async window dragging by
	the window server; set the corresponding window attribute by default.

	* macosx/tkMacOSXMouseEvent.c: rationalized handling order of
	non-mousedown events; add TkMacOSXModifierState() to retrieve the
	current key modifiers in carbon format.

	* macosx/tkMacOSXScrlbr.c: use appearance manager API to retrieve
	scrollbar component metrics; add awareness of multiple possibilites for
	scrollbar arrow position in aqua and handle user changes to arrow
	position pref; handle difference in metrics of small & large scrollbar
	variants; handle aqua "jump to here" scrollbar behaviour; correct
	computation of scroll view size and position; enforce min scrollbar
	height to avoid scrollbar component overlap; erase scrollbar area
	outside of standard width; remove broken auto-adjust code; account for
	window class when leaving space for grow box; remove code to manually
	draw grow box; use modern API for thumb scroll proc; replace
	HiliteControl() by modern API; replace control mgr constants with
	appearance mgr equivalents.

	* macosx/tkMacOSXSubwindows.c: use SetWindowBounds() API instead of
	SizeWindow(); invalidate clip regions after X{Map,Unmap}Window as fix
	for [Bug 940117] made them dependent on mapping state; remove unneeded
	calls to TkMacOSXInvalClipRgns() and unnecessary setting of QD port;
	use native-endian pixmap on intel; remove obsolete pixmap pix locking.

	* macosx/tkMacOSXWindowEvent.c: handle only the first of a batch of
	kEventAppAvailableWindowBoundsChanged events sent per transaction;
	handle kEventWindowBoundsChanged event to support live window resizing
	and centralized sending of location/size changed ConfigureNotify
	events; ensure HIGrowBox is redrawn after bounds change; constrain
	window after dragging to ensure titlebar is not inacessible
	offscreen or under dock/menubar; handle kEventWindowGetRegion and
	kEventWindowDrawContent for transparent windows to mark resp. paint
	content region as transparent; handle kEventWindowConstrain for
	fullscreen windows to ensure bounds match new screen size; enter/exit
	fullscreen UIMode upon activation/deactivation of fullscreen window.

	* macosx/tkMacOSXWm.c: use live-resize and async-drag carbon window
	* macosx/tkMacOSXWm.h: attributes for toplevels by default; implement
	new [wm attributes] -topmost, -transparent and -fullscreen; refactor
	WmAttributesCmd() parallelling the tkUnixWm.c implementation, use thus
	factored proc to set proxy icon from [wm iconbitmap]; dynamically
	determine default values for toplevel min and max sizes (similar to
	tkWinWm.c impl): min sizes depend on window class & attributes to
	ensure visibility of all titlebar widgets and grow box, max sizes
	depend on maximal window bounds for all active displays; factor out
	code that puts into effect changes to master or override_redirect; use
	RepositionWindow() API to determine staggered initial window bounds;
	correct resize limit calculations, handle gridding and use modern
	resize API in TkMacOSXGrowToplevel(); remove sending of ConfigureNotify
	after resize or zoom (now handled by BoundsChanged handler); correct
	composite carbon window attribute handling, remove currently unusable
	attributes and add new attributes in [tk::unsupported::MacWindowStyle];
	ensure validity of window class and attributes before use; apply
	changes to window class when handling carbon window attribute changes
	(if HIWindowChangeClass() API available); add debug build warning
	message when deprecated window style is used instead of window class;
	use transparent HIGrowBox for resizable windows; avoid unnecessary
	calls to window structure width API; use tcl time API in TkpGetMS();
	add TkMacOSXEnterExitFullscreen() to enter/exit UIMode with dock and
	menubar hidden; restrict wmTracing output to debug builds; remove
	unneeded calls to TkMacOSXInvalClipRgns() and unnecessary setting of QD
	port; workaround GetWindowStructureWidths() Carbon bug (bogus results
	for never-mapped floating windows).

	* macosx/tkMacOSXXStubs.c (TkMacOSXDisplayChanged): add maximal window
	bounds field to Screen record (in ext_data), computed as the union of
	available window positioning bounds of all graphics devices (displays).

	* macosx/tkMacOSXBitmap.c: fix macRoman encoding leak.
	* macosx/tkMacOSXCursor.c:

	* macosx/tkMacOSXDebug.c (TkMacOSXCarbonEventToAscii): use static
	* macosx/tkMacOSXDebug.h: buffer to simplify callers; const fixes.

	* macosx/tkMacOSXBitmap.c: use more efficient QDSwapPort() instead of
	* macosx/tkMacOSXButton.c: GetPort()/SetPort()/GetGWorld()/SetGWorld().

	* macosx/tkMacOSXInit.c (TkpInit): reorder initialization steps.

	* macosx/tkMacOSXKeyEvent.c: remove pre-10.2 support.

	* macosx/tkMacOSXMenus.c: remove now useless call to
	TkMacOSXHandleTearoffMenu(); use \x.. quoting for non-latin1 macroman
	literar chars to allow file to be edited as utf-8.

	* macosx/tkMacOSXScale.c: replace TrackControl() by modern
	* macosx/tkMacOSXScrlbr.c: HandleControlClick() API (using new
	TkMacOSXModifierState()).

	* macosx/tkMacOSXInt.h:		move all constant #defines needed to

	* macosx/tkMacOSXEvent.h:	to a central location in tkMacOSXInt.h.
