	* src/main.c: Add print_debugging variable / debug_print startup
	option.
	(gnumeric_main): Make stdout line buffered - we only use it for
	debug info.

	* src/print-cell.[ch] (print_make_rectangle_path): New function: make
	a rectangular gnome-print path.
	* src/print-cell.c (print_cell): Use it.

	* src/print.c (print_empty_pages variable): Remove. This variable
	is never set. With the new repeated row/column handling, the logic
	will have to be rewritten anyway if needed.
	(print_page_repeated_rows): Remove unused parameters start_row and
	end_row.
	(print_page_repeated_cols): s/row/col/. Fix bug - was repeat_left,
	corrected to repeat_top.
	(print_page_object): Remove unused parameters page_width /
	page_height and end_col / end_row.
	(print_hf_element): Rename from print_hf
	(print_hf_line): New function. Logic shared by print_header and
	print_footer. Clip to header region. if print_debugging != 0, draw
	a box around header region.
	(print_headers): Use print_hf_line. Place at correct y position -
	ascenders flush with inside of top margin.
	(print_footers): Descenders flush with inside of bottom
	margin. Otherwise like headers.
	(print_page): Include logic for repeated rows and columns: They
	are only repeated after the start of the repeating range has been
	seen in the regular page flow. Fix grid size bug when centering
	horizontally or vertically. Use print_make_rectangle_path.  Remove
	print_empty_pages logic.
	(compute_group): New function. Old compute groups changed to only
	compute one page. Rationale: Available space on page for normal
	cell flow changes once repeated rows/columns kick in, so there is
	no gain in precomputing a list.
	(render_sheet_objects): New function. Factored out of
	print_sheet_range.
	(print_range_down_then_right): New function. Used to be the row
	major loop of print_sheet_range. Include logic for repeated rows
	and columns (see print_page).
	(print_range_right_then_down): s/row major/column major/
	(print_sheet_range): Restructure into a small function that calls
	render_sheet_objects, print_range_down_then_right,
	print_range_right_then_down.
	(compute_sheet_pages): Remove print_empty_pages logic. The
	variable is never set. With the new repeated row/column handling,
	the logic will have to be rewritten anyway if needed.
	(compute_sheet_pages, print_sheet): Remove "key" parameter because
	we are now called from g_list_foreach instead of
	g_hash_table_foreach.

	(compute_pages): Use list returned by workbook_sheets instead of
	wb->sheets so sheets are processed in order.
	(workbook_print_all): Print sheets in display order. To do so, use
	list returned by workbook_sheets instead of wb->sheets.
	(sheet_print): Use changed print_sheet signature.

	* src/workbook.h (struct _Workbook): Rename "sheets" to
	sheet_hash_private.

	* src/workbook.c (workbook_do_destroy, workbook_do_destroy,
	workbook_set_dirty, workbook_is_dirty, workbook_is_pristine,
	workbook_init, workbook_rename_sheet, workbook_sheet_count,
	workbook_attach_sheet, workbook_detach_sheet,
	workbook_sheet_lookup): s/wb->sheets/wb->sheet_hash_private/
	(cb_assemble_selection, workbook_selection_to_string): Not in
	use. Remove.

	* src/workbook-view.c (workbook_view_pref_visibility):
	s/wb->sheets/wb->sheet_hash_private/
