/**
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 .
