+ * generic/tkCanvUtil.c (TkSmoothParseProc): recognize the built-in
+ bezier method by name. [Bug #578654]
+ * doc/canvas.n: update to note that -smooth really doesn't take
+ or return just booleans.
+
* win/tkWinMenu.c (TkpSetWindowMenuBar): fixed logic bug in when
to idle call ReconfigureWindowsMenu.

It indicates whether or not the line should be drawn as a curve.
If so, the line is rendered as a set of parabolic splines: one spline
is drawn for the first and second line segments, one for the second
