* macosx/tkMacOSXWindowEvent.c (GenerateUpdateEvent): complete all

	pending idle-time redraws before newly posted Expose events are
	processed; add bounds of redrawn windows to update region to ensure all
	child windows overdrawn by parents are redrawn.

	* macosx/tkMacOSXWindowEvent.c:	centralize clip and window invalidation
	* macosx/tkMacOSXSubwindows.c:	after location/size changes in the
	* macosx/tkMacOSXWm.c:		BoundsChanged carbon event handler;
	correct/add window invalidation after window attribute changes.

	* macosx/tkMacOSXSubwindows.c (XResizeWindow, XMoveResizeWindow,
	XMoveWindow): factor out common code dealing with embedded and
	non-toplevel windows; remove unnecessary clip and window invalidation.

	* macosx/tkMacOSXButton.c (TkpDisplayButton): move clip setup closer to
	native button drawing calls.

	* macosx/tkMacOSXWm.c (TkMacOSXIsWindowZoomed, TkMacOSXZoomToplevel):
	correct handle gridded windows in max size calculations.

	* macosx/tkMacOSXEvent.c (TkMacOSXFlushWindows): use HIWindowFlush API
	when available.

	* macosx/tkMacOSXColor.c:	cleanup whitespace and formatting.
	* macosx/tkMacOSXDraw.c:
	* macosx/tkMacOSXSubwindows.c:
	* macosx/tkMacOSXWm.c:
