+/*  [Description]
+
+    Left/Right margin and first line indent
+
+    SvxLRSpaceItem offers two interfaces for views from the left margin and
+    first line indent. The get methods return the member, with the layout also
+    as expected: the left edge shifts to the negative first line indent to the
+    left. The SetTxt/Gettxt methods assume that the left side represents the
+    0 coordinate for the first line indent:
