Dump in the RTL code that has been simmering waiting for a branch

2005-01-20  Jody Goldberg <jody@gnome.org>

	* src/xml-io.c (xml_sheet_write) : store the rtl flag
	(xml_sheet_read) : read the rtl flag

	* src/workbook-control-gui.c (cb_notebook_switch_page) : set the
	  direction on page change
	(show_gui) : setting it here too.
	(set_dir) : new.
	(wbcg_set_direction) : new

	* src/wbcg-actions.c (cb_direction) : A quick and simple direction
	  setting action.  We need a better icon, and improved state.

	* src/style-border.c (style_border_hmargins) : lots of finicky
	  -1*offset style changes for rtl.

	* src/sheet.c (gnm_sheet_class_init) : Add some as yet unused get/set
	  property routines.
	(gnm_sheet_init) : new to init the direction based on the locale.  Use
	  a gtk routine for now.  There's a bug open to have that moved to
	  glib.
	(sheet_set_direction) : new.

	* src/sheet-view.c (sv_init_sc) : init the direction.
	(sv_direction_changed) : new.

	* src/sheet-object-cell-comment.c (comment_view_set_bounds) : fold the
	  old comment_get_points into here and invert things in RTL mode.

	* src/sheet-control-gui.c (scg_redraw_headers) : col coordinates are
	  negative for rtl mode.
	(scg_resize) : rework for rtl
	(scg_set_zoom_factor) : ditto.
	(bar_set_left_col) : ditto.
	(bar_set_top_row) : ditto.
	(gnm_canvas_set_top_left) : ditto.
	(calc_obj_place) : ditto.  Clarify which coordinate system we're in.
	(scg_direction_changed) : new virtual.
	(scg_scale_changed) :  renamed from scg_set_zoom_factor.

	* src/print.c (print_sheet_objects) : handle rtl. (needs testing)
	(print_page_cells) : simple rtl handling

	* src/mstyle.c : Add a text_dir element that defaults to CONTEXT right
	  now.  This is unused until it is better understood, but it is read
	  and written from xls.  We need to add xml support.

	* src/item-grid.c (item_grid_draw_merged_range) : handle rtl
	(item_grid_draw) : ditto.
	* src/print-cell.c (print_merged_range) : ditto
	(print_cell_range) : ditto.

	* src/item-edit.c (ie_layout) : swap directions in RTL mode.  We still
	  need more work here to honour the alignment better while editing.

	* src/item-cursor.c
	(item_cursor_request_redraw) : delete, we can use foo_canvas_item_request_redraw
	(item_cursor_update) : handle rtl
	(item_cursor_draw) : ditto
	(item_cursor_bound_set) : add some safety to avoid drawing before the
	  position is set, or if it is set to something invalid

	* src/item-bar.c (item_bar_draw) : major rework to handle RTL mode.
	  - swap the the direction for the cells and the outlines
	(is_pointer_on_division) : handle rtl and clarify which coordinate
	  system the various inputs and results use.
	(ib_set_cursor) : simplify
	(outline_button_press) : RTL flips some coordinates.
	(item_bar_event) : ditto

	* src/gnumeric-simple-canvas.c (gnm_simple_canvas_x_w2c) : doh! handle
	  zoom

	* src/gnumeric-pane.c (gnumeric_pane_header_init) : handle rtl
	(gnm_pane_init) : ditto.
	(gnm_pane_colrow_resize_start) : ditto.
	(gnm_pane_colrow_resize_move) : ditto.
	(cb_slide_handler) : ditto.

	* src/gnumeric-canvas.c (gnm_canvas_key_mode_sheet) : Swap the
	  direction of arrow keys in rtl mode.
	(gnm_canvas_key_mode_object) : ditto
	(gnm_canvas_size_allocate) : always recompute visible range.  In RTL
	  mode we want to have things aligned on the left edge whose coord
	  moves.
	(gnm_canvas_find_col) : handle the rtl negation of world coords
	(gnm_canvas_redraw_range) : ditto
	(gcanvas_sliding_callback) : ditto.
	(gnm_canvas_handle_motion) : ditto.
	  NOTE : work around a bug in gtk's use of X.  When dragging past the
	  right edge of the sheet in rtl mode we are operating at the edge of
	  a 32k wide window and the event coords get larger than can be held
	  in a signed short.  As a result we get world coords of -65535 or so.
	  KLUDGE KLUDGE KLUDGE
	    with our current limit of 256 columns it is unlikely that we'll
	    hit -65535 (at appropriate zoom) as a valid coord (it would
	    require all cols to be 256 pixels wide.  it is not impossible, but
	    at least unlikely.  So we put in a kludge here to catch the screw
	    up and remap it.   This is not pretty,  at large zooms this is not
	    far fetched.
	(gnm_canvas_compute_visible_region) : things are more complicated for
	  rtl mode.

	* src/commands.c : Add undo for the rtl vs ltr mode

	* src/cellspan.c (cell_calc_span) : in rtl mode swap the meaning of
	  horizontal alignment.

	* src/GNOME_Gnumeric-gtk.xml.in : Add the rtl toggle action

2004-12-07  Jody Goldberg <jody@gnome.org>

	* ms-excel-write.c (excel_write_WINDOW2) : export sheet level rtl
	  setting (we could move it to SheetView)
	(build_xf_data) : store the text dir.
	(excel_write_XF) : write it.

	* ms-excel-read.c (excel_read_WINDOW2) : read sheet level rtl flag
	(excel_read_XF) : read the text dir.
	(excel_get_style_from_xf) : store the text dir.

	* dialog-sheet-order.c : Support a toggle for rtl
