+/** Stores frame styles of an array of cells, supports merged ranges.
+
+ This class is able to store the frame styles of an array of cells and to
+ draw the entire array or parts of it to any output device.
+
+ Every cell contains the style of the left, right, top, bottom, top-left to
+ bottom-right, and bottom-left to top-right frame border.
+
+ On drawing, the thicker frame border of neighbored cells is selected
+ automatically. All borders are drawn "connected", that means, the correct
+ start and end coordinates of all lines of the borders are calculated,
+ especially, if they are drawn together with diagonal frame borders.
+
+ This array fully supports merged cell ranges. In a merged range, the frame
+ borders of the top-left cell is extended to the entire range, and all other
+ cells in that range are overlapped. Again, all connected frame borders,
+ also diagonals and frame borders from adjacent merged ranges, are handled
+ automatically.
+
+ Additionally, a clipping range can be set. If such a range is used, all
+ frame borders outside this range are completely ignored, and are not used
+ in the connected border calculation anymore.
+
+ The array can be mirrored in both directions. It is possible to specify,
+ whether to mirror the double frame styles, and whether to swap diagonal
+ frame borders.
