	* ms-excel-read.c (ms_excel_read_pane) : new function.
	(ms_excel_read_sheet) : called from here.
	(ms_excel_read_window2) : top left spec is _zero_ based.

	* src/item-cursor.c (item_cursor_in_drag_handle) : bounding coords
	  mark the outside of the drag box, center things before checking.
	(item_cursor_selection_event) : be smarter about handling double
	  clicks.  This could still be improved see comment.

	* src/sheet.c (sheet_cell_calc_span) : clear existing span before
	  recalculating it.
	(sheet_cell_set_text) : clear existing spans for expressions.
	(sheet_cell_set_expr): ditto.

	* src/cellspan.c (cellspan_is_empty) : rename from cell_is_empty
	  and change order of args to make it clear that the Cell in the cell
	  in that arg list is _not_ the one being tested for emptiness.  Do
	  the empty chacek manually because expressions with initial value
	  'empty' are allowing other cells to continue spanning into them.
	  However, since the expressions don't calc spans yet, the cell
	  content is never made visibible.

	* src/sheet-control-gui.c (scg_resize) : increase the size of the
	  header canvases by 1.  I don't especially like the like, but I have
	  no time to track down why the canvas scrolls by 1 pixel if I don't
	  do this.
	(cb_control_point_event) : partially fix sheet object movement.

	* src/gnumeric-sheet.c (gnumeric_sheet_slide_stop) : renamed from
	  gnumeric_sheet_stop_sliding.
	(col_scroll_step) : new function.
	(row_scroll_step) : new function.
	(gsheet_sliding_callback) : rewrite again to manage scrolling for
	  panes more smoothly.  Still needs work.
	(gnumeric_sheet_handle_motion) : handle motin into adjacent panes
	  here.
	(gnumeric_sheet_slide_init) : new routine to set adjacency earlier in
	  process.

	* src/item-bar.c (item_bar_event) : call gnumeric_sheet_slide_init.
	* src/item-cursor.c (item_cursor_selection_event) : ditto.
	(item_cursor_drag_event) : ditto.
	* src/item-grid.c (item_grid_button_1) : ditto.

	* src/gnumeric-pane.c (gnumeric_pane_header_init) : no need to
	  calc_size here.  That will be done when the item is realized.

	* src/sheet-control-gui.c (scg_set_left_col) : And bounds checks and
	  safety.
	(scg_set_top_row) : ditto.

	* src/item-cursor.c (item_cursor_draw) : Add a simple test for pane
	  support when placing the drag handle.
