/** Contains the widths of primary and secondary line of a frame style.
In the following, "frame style" is a complete style of one frame border,
i.e. the double line at the left side of the frame. A "line" is always a
trivial single line, i.e. the first line of a double frame style.
The following states of the members of this struct are valid:
mnPrim mnDist mnSecn frame style
-------------------------------------------------
0 0 0 invisible
>0 0 0 single
>0 >0 >0 double
The behaviour of the member functions for other states is not defined.
Per definition the primary line in double frame styles is:
- The top line for horizontal frame borders.
- The left line for vertical frame borders.
- The bottom-left line for top-left to bottom-right diagonal frame borders.
- The top-left line for bottom-left to top-right diagonal frame borders.
The following picture shows the upper end of a vertical double frame
border.
