+/**
+    Class computing border widths shared between Line style listbox and the
+    SvxBorderLine implementation.
+
+    This class doesn't know anything about units: it all depends on the different
+    values set. A border is composed of 2 lines separated by a gap. The computed
+    widths are the ones of each line and the gap and they can either be fix or vary.
+
+    The #m_nflags member will define which widths will vary (value 0 means that all
+    widths are fixed). The available flags are:
+     - CHANGE_LINE1
+     - CHANGE_LINE2
+     - CHANGE_DIST
+
+    For each line, the rate member is used as a multiplication factor is the width
+    isn't fixed. Otherwise it is the width in the unit expected by the client code.
