From 370d7890a333ca002af41884cde93ca62231debb Mon Sep 17 00:00:00 2001
From: Stefan Schimanski <sts@lyx.org>
Date: Fri, 15 Jun 2007 18:26:35 +0000
Subject: [PATCH] * Added the kerning method to a macro to inherit the kerning
 from the expanded form. * Moreover the marker metrics calls are removed as
 they are not drawn anyway. (fixes #3705)
