* changes: updates for 8.5a5 release.

	* macosx/tkMacOSXDraw.c: fix numerous issues in CG and QD drawing procs
	so that they now match X11 drawing much more closely [Bug 1558051];
	use Tiger ellipse drawing API when available; fix comments & whitespace.

	* macosx/tkMacOSXInit.c: set default linewidth limit for CG
	antialiasing to 0 as thin horizontal/vertical lines look good now.

	* generic/tkCanvLine.c (ConfigureLine):     on TkAqua, pass outline
	* generic/tkCanvPoly.c (ConfigurePolygon):  linewidth in gc even for
	* generic/tkRectOval.c (ConfigureRectOval): fills (as it controls AA).
