/**
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.
