- Use DASH_ON_OFF to correctly handle borders for cells with a background
  colour.

- Prefer Top/Left vs Bottom/Right.  This works around problems with borders
  for cells with backgrounds..  BUT does not solve it for importing.  That
  will require the next generation border code that has yet to be designed.

- A crappy implementation of double borders.  Does NOT handle cells with
  backgrounds, or the myriad intersection cases.

- Improve handling of undo and redraw for borders.

	* src/sheet.c (sheet_cursor_set) : Be religous about handing edit_pos
	  changes.

	* src/commands.c (cmd_format) : save for formats for a range 1 cell
	  thick around the selection so that borders are handled.

	* src/sheet-view.c (sheet_view_redraw_cell_region) : Redraw a border
	  around the selected region to handle thick borders */

	* src/sheet-object.c (sheet_object_canvas_event) : Ignore mouse wheel
	  events.

	* src/border.c (style_border_set_gc_dash) : Use GDK_LINE_ON_OFF_DASH
	  so that background colours show through.

	* src/sheet-style.c (sheet_range_set_border) : Prefer top vs bottom
	  and left vs right.  This will simplify drawing eventually.
