+ 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.
