Fix bug in cell_set_formula_tree_simple

Deep freeze/thaw of cell redraws implemented.
XML-io now freezes / thaws for speed on load.

Speedups using this for ms-excel numbers also gives better precision.

Graphic Wizard touch ups.
Gnumeric got a decent CORBA interface.
Gnumeric got an implmeneation for above cool CORBA interface

Miguel

crashes.  Fixes parts of column/row insert/delete.

More work on the graphics wizard.

	* src/sheet.c (sheet_destroy): No longer destroys the Bonobo
	objects here.

	* src/sheet.h (Sheet): No longer keeps track of the ClientSites
	here.

	* src/sheet-object.c (sheet_finish_object_creation): Invoke new
	class method to signal finalization of object creation.

	* src/sheet-object-container.c, src/sheet-object-container.h: New
	files that implement the Bonobo ClientSites
	(SheetObjectContainers).

	* src/Makefile.am (gnumeric_bonobo_SOURCES): Sources for Bonobo
	compilation.

	* src/sheet-object.c (sheet_object_construct): Create the bounding
	box points here.
	(sheet_set_mode_type): Fix from my previous reorganization:  Only
	stop editing mode if the mode is SHEET_MODE_SHEET.
	(sheet_button_press): Strategy change: now we accept
	sheet->current_object and we stop editing here the object.

	* src/sheet-object.h: points has been renamed to bbox_points.

	* src/sheet-object-graphic.c (sheet_object_filled_realize):
	Simplified this routine.  Also, we now update the bounding box
	here.

Added PTG_AREA_N, Added PTG_ARRAY bits ( untested ),
Standardised number transfer fixing some problems.

	* src/cell.c (cell_destroy): From Morten Wellinder: destroy the
	cell->value only if it does exist.

1999-04-05  Morten Wellinder <terra@diku.dk>

	* src/cell.c (cell_set_rendered_text): Fix for circular
	references.

1999-04-05  Miguel de Icaza  <miguel@nuclecu.unam.mx>

	* src/about.c (dialog_about): Do not make the about box modal.

1999-03-14  Miguel de Icaza  <miguel@nuclecu.unam.mx>

	* src/expr.c (bigger_prec): When decoding left-to-right apply
	parentheses if the two priorities are equal.

1999-03-11  Miguel de Icaza  <miguel@nuclecu.unam.mx>

	* src/clipboard.c (sheet_paste_selection): New routine.  Abstracts
	the paste operation.
	(clipboard_paste_region): Now it uses a clipboard with the active
	X selection instead of defaulting to "request clipboard from X"
	(this is only for inter-workbook copy-paste).

	* src/sheet.c (find_workbook_with_clipboard): Tries to find a
	workbook with clipboard information.  Probably the clipboard
	should be global to all Gnumeric.

	* src/render-ascii.c (cell_region_render_ascii): Free the
	information after we have used it, not before.

	* src/expr.c (eval_expr): Handle new-born recursive references.

Text export filter from Takashi Matsuda.

Cleaned debug output

1999-02-23  Miguel de Icaza  <miguel@nuclecu.unam.mx>

	* src/cell.c (cell_draw): If the cell has a render_color (provided
	by the format specification), use that for the foreground.

fatal bugs fixed.

1999-02-19  Miguel de Icaza  <miguel@nuclecu.unam.mx>

	* src/clipboard.c (paste_cell): Do not render the value if the
	result is an error.

	* src/cell.c (cell_copy): Do not copy the value of a cell when the
	value is NULL (due to the cell having an error).

	* src/expr.c (eval_expr): Evaluate binary operations in parts to
	keep the correct error message on an operation if possible.
	(eval_expr): Propagate errors.

	* src/item-edit.c (item_edit_draw): Sync the before-cursor and
	after-cursor Y-display text cordinate.

	* src/expr.c (eval_funcall): Add type checking for the simple
	functions.

	* doc/C/Makefile.am (install-data-local): use topsrcdir here (fix
	from Ian Campbell <ijc25@cam.ac.uk>

	* src/fn-math.c (gnumeric_not): Implement NOT.

* src/cell.c (cell_draw): Now the function draws the cell
using the cell background color setting. Although it does
the job, I guess there must be a better way to do it. Thanks
to Michael for the hint.

* src/item-grid.c (item_grid_draw_cell): Commented out the lines
involved with patterns display in the cell, for that code is
not ready yet.

* src/dialog-cell-format (create_coloring_page): Reactivated
the background selection panel of the coloring page.

* src/dialog-cell-format (create_background_radio): Commented out
the addition of the pattern selection for a cell.

1999-02-10  Miguel de Icaza  <miguel@nuclecu.unam.mx>

	* src/cell.c (cell_relocate): When relocating a cell with a
	formula, always mark it as changed.  We were doing that before
	only for the case where the location had changed, but we use
	cell_relocate in other cases as well.

	* src/fn-string.c (gnumeric_lower, gnumeric_upper): These
	functions were wrong.  They were never incrementing the pointer
	and they were releasing the wrong pointer.

	* src/clipboard.c (paste_cell): When pasting a cell, mark the
	contents as modified.

	* src/file.c (file_saver_is_default_format): Make sure the saver
	is always set.

	* src/cell.c (cell_draw): Make the clip region one pixel bigger to
	account for the offset.
	(cell_draw): Do not add one to text_base.

	* src/item-edit.c (item_edit_draw): Take into account the margin_b.

1999-02-07  Miguel de Icaza  <miguel@nuclecu.unam.mx>

	* src/cell.c (cell_set_text_simple): Allow a single "=" to
	represent a string.

Coding style fixes;  Indentation fixes

1999-01-10  Miguel de Icaza  <miguel@nuclecu.unam.mx>

	* src/eval.c (add_value_deps): Reorganization.  Hanlde
	VALUE_CELLREF here and make OPER_VAR and OPER_CONSTANT call
	add_value_deps.

	* src/expr.c (do_expr_tree_relocate, expr_tree_relocate): New
	routine that returns an ExprTree relocated.
	(value_copy_to): Handle the VALUE_CELLREF type.

	* src/expr.h: define VALUE_CELLREF

	* src/parser.y (yylex): Type fix.
	When creating values of type VALUE_CELLREF, set this value.

1999-01-09  Miguel de Icaza  <miguel@nuclecu.unam.mx>

	semantics.
	(sheet_shift_row): ditto.
	(sheet_insert_row): ditto.
	(sheet_delete_row): ditto.

	* src/clipboard.c: Update to new cell_relocate semantics.
	Remove the old GTK compatibility code.

	* src/cell.c (cell_relocate): We do not need to reference this
	formula.
	This routine now takes delta-x and delta-y values for the
	relocation, instead of absolute cordinates.  To implement the
	proper semantics of cell movement that other spreadsheets implement

1999-01-04  Miguel de Icaza  <miguel@nuclecu.unam.mx>

	* src/sheet.c (sheet_rename): New routine.

	* src/workbook.c (workbook_attach_sheet): Use a EditableLabel for
	the notebook tab.
	(workbook_rename_sheet): New routine.

	* src/widget-editable-label.c:  New widget.  This is a label that
	can be edited if you double click on it.  This uses the same trick
	of the gnome-icon-item to provide the editing facilities.

1999-01-03  Miguel de Icaza  <miguel@nuclecu.unam.mx>

	* src/workbook.c (workbook_setup_status_area): Use the style font,
	not "fixed".
	(workbook_setup_status_area): One hack down.  Use GTK_ANCHOR_NW to
	achieve the same effect I had with my previous hack.

	* src/dialog-cell-comment.c (dialog_cell_comment): New file.
	Implements the cell comment dialog box.

	* src/cell.c (cell_relocate): Only call cell_comment_reposition is
	there is a cell comment bound to this cell.

	formatting instead of 0.00.

1998-12-28  Miguel de Icaza  <miguel@nuclecu.unam.mx>

	* src/cell.h: cell->entered_text is back, now only used for typo
	correction.  Maybe I will use it for saving.

	* src/fn-string.c (gnumeric_right): Use value_str.

1998-12-28  Miguel de Icaza  <miguel@nuclecu.unam.mx>
