* macosx/tkMacOSXDraw.c: replace all (internal) use of QD region

	* macosx/tkMacOSXSubwindows.c:	API by HIShape API, with conversion to
	* macosx/tkMacOSXWindowEvent.c	QD regions only when required by legacy
	* macosx/tkMacOSXPrivate.h:	Carbon or Tk API.
	* macosx/tkMacOSXRegion.c:
	* macosx/tkMacOSXDebug.c:
	* macosx/tkMacOSXDebug.h:

	* macosx/tkMacOSXInt.h:		replace MacDrawable's QD RgnHandles
	* macosx/tkMacOSXEmbed.c:	clipRgn, aboveClipRgn & drawRgn by
	* macosx/tkMacOSXMenu.c:	HIShapeRefs visRgn & aboveVisRgn and
	* macosx/tkMacOSXSubwindows.c:	CGRect drawRect.

	* macosx/tkMacOSXWindowEvent.c:	remove use of QD port vis rgn in window
	* macosx/tkMacOSXSubwindows.c:	update rgn calculation, manually excise
	* macosx/tkMacOSXWm.c:		growbox from toplevel clip rgn instead.

	* macosx/tkMacOSXDraw.c:	replace use of QD port clip rgn by new
	* macosx/tkMacOSXPrivate.h:	clipRgn fld in TkMacOSXDrawingContext;
					handle QD/CG drawing mismatches in
					XCopyArea, XCopyPlane and TkPutImage;
					cleanup/speedup CGContext setup in
					TkMacOSXSetupDrawingContext().

	* macosx/tkMacOSXDraw.c:	change TkMacOSXSetupDrawingContext() to
	* macosx/tkMacOSXEntry.c:	return boolean indicating whether
	* macosx/tkMacOSXFont.c:	drawing is allowed (and was setup) or
	* macosx/tkMacOSXMenu.c:	not (e.g. when clipRgn is empty).
	* macosx/ttkMacOSXTheme.c:

	* macosx/tkMacOSXSubwindows.c:	signal that drawable is a pixmap via
	* macosx/tkMacOSXInt.h:		new explicit TK_IS_PIXMAP flag instead
					of a NULL cligRgn field.

	* macosx/tkMacOSXRegion.c:	add wrappers for missing/buggy HIShape
	* macosx/tkMacOSXPrivate.h:	API, and private helpers to operate on
					HIShapeRefs & convert to/from TkRegion.

	* macosx/tkMacOSXRegion.c:	add Tkp{Retain,Release}Region() API for
	* macosx/tkMacOSXInt.h:		TkRegion.
