	* src/sheet.c (sheet_reposition_comments) : Merged from
	  sheet_reposition_comments_from_row and
	  sheet_reposition_comments_from_col.

	(sheet_update) : New function.  Use the new update flags from
	  SheetPrivate that are set in the col/row resize functions
	  to do delayed resizing and updates.  This allows the resizing to be
	  batched for an entire logical operation.
	(sheet_{col,row}_set_size_pixels) : Set the update flags.

	* src/workbook-cmd-format.c (workbook_cmd_format_{row,column}_auto_fit) : No need to
	  worry about redraws.  Use sheet_update.
	(workbook_cmd_format_{row_height,column_width}) : Ditto.

	* src/sheet-view.c (sheet_view_redraw_cell_region) : No need to
	  recalculate the spans,  Use the pre-calculated versions.
	(sheet_view_col_size_changed) : Use sheet_update.
	(sheet_view_row_size_changed) : Ditto.

	* src/sheet-style.c (re_dimension_cells_cb) : Use cell_calc_dimensions.
	(sheet_cells_update) : No need to redraw per cell and guess the bound.
	  It is simpler and more correct to calc dimension per cell, and
	  redraw the region BEFORE and AFTER to handle spans.

	* src/cell.[ch] (cell_style_changed) : Delete.

	* src/cell-draw.c (cell_draw) : continue syncing with print code.
	  Be even more careful in the possible presence of style bugs.
	* src/item-grid.c (item_grid_draw) : Ditto.
	* src/print-cell.c (print_cell) : Ditto.

	* src/analysis-tools.c (correlation_tool) : Use sheet_update.
	(covariance_tool) : Ditto.
	(ttest_paired_tool) : Ditto.
	(ttest_eq_var_tool) : Ditto.
	(ttest_neq_var_tool) : Ditto.
	(ftest_tool) : Ditto.

	* src/sheet-private.h : Add status flags to accumulate state changes
	  for later redraw.

	* src/commands.c (cmd_format_redo) : Use sheet_update
	  in case the row/col sizes changed due to font size changes.
	(cmd_format_undo) : Ditto.

	* src/widgets/gtk-combo-box.c (cb_state_change) : Only pseudo-prelight
	  the display when over the arrow, not vice versa.
	(gtk_combo_box_init) : Ditto.
	(gtk_combo_box_set_display) : Ditto.

	* src/sheet.c (sheet_row_get_distance_pts) : Enable reversed indicies.
	(sheet_col_get_distance_pts) : Ditto.

	* src/plugin.c (plugin_load) : Add more version checking to ensure
	  that very old plugins that do not check their versions can not be
	  loaded.

	* src/gnumeric-sheet.c (gnumeric_sheet_make_cell_visible) : When
	  forcing a scroll do a hard reset of the visible ranges.
	(gnumeric_sheet_compute_visible_ranges) : Ditto.
	(gnumeric_sheet_set_top_row) : Remove extraneous scroll.
	(gnumeric_sheet_set_left_col) : Remove extraneous scroll.
