      	* src/eval.c (cell_eval): Use the formating routine now.
      
      	* src/expr.c (value_format): Format a Value with a StyleFormat.
      
      	* src/item-cursor.c (item_cursor_set_bounds_visibly): Force a
      	canvas update after moving the selection.
      
      	* src/sheet.c (sheet_selection_to_list): New function: generates a
      	list of cells from the sheet->selections list.
      
      	* src/style.c: Now styles have a "valid_flag" that has a bit
      	turned on for those parts of the style that are actually used.
      	This is required for adding the regions of style application in a
      	Sheet.
      	(style_destroy): destroy only those valid parts in a style.
      
      	* src/dialog-cell-format.c: New file.   Implements the cell/format
      	dialog box.
      
      	* src/cell.c (cell_render_value): new routine used to render the
      	cell->value into cell->text.
      	(cell_queue_redraw): new routine to queue individual redraws of
      	the screen.  I believe it is buggy, as the screen does not update
      	after an apply in the cell/format dialog box.
      	(cell_set_format): New routine to change the format of an existing
      	cell.
      
      	* src/format.c (format_number): Added color argument;  smaller
      	fixes to use it within gnumeric.
      
      	* src/main.c (main): Include i18n setup as per namsh's suggetion.

      Various little fixes here and there:
      
      	- Basic support for dragging the selection is in (still does
      	  not do anything, will do the action binding later).
      
      	- Fixes to the cell-selection-code-when-you-type-a-formula code
      
      	- ExprTrees are now properly refcounted (instead of only
      	  refcounting the root node).  This is required for the
      	  Paste special/with-arithmetic operation feature.
      
      	- Expression decoding (for pasting a formula with relative
      	  references) now takes into account operator precedence to
      	  avoid cluttering the pasted expression with extra paretheses.
      
      	Other smallish fixes which I forget now.
      
      Miguel.

      It autocalcs!
      
      My technique is incredibly cool!  The engine should support
      most excel features for recursive computations (we just need
      the dialog boxes now).
      
      It still has a wierdo crash from a mismatched string ref/unref
      but that is going to be trivial to fix.
      
      Next step:  Functions in Perl.

      Today it probably does not compile, but I have to leave now.
      
      This is basically the framework for getting computations working.
      
      My current approach is to register areas of interest for a cell.
      This is not perfect, but good enough:
      
      	The idea is to walk the expression tree and look for
      	cell references (cell references or ranges) and register
      	those areas of "interest" for a cell.
      
      	When a new text is entered into a cell, the "regions" of
      	interest list is checked and if a match is found, then
      	the cells on that region of interest are queued for
      	recomputation.
      
      Of course, I do not know yet how to handle the recursive references.
      
      One option is to keep a counter (that starts at zero) during
      recomputation, ie something like:
      
      eval_cell (Cell *cell)
      {
      	cell->use_count++;
      	if (cell->use_count > threshold)
      		return "Cycle too depth";
      	...
      	on value lookup:
      		eval_cell (cell);
      	...
      	cell->use_count--;
      }

      Lots of things today:
      
      - New functions implemented:
      	SELECTION(),  SUM(),  IF()
      
      - Autocompute of an expression that applies to the selection.
      
      - Added comparission to the expression grammar.
      
      - Added array values.
      
      Bug fixes as usual and lots other thingies I forget.

      Weee!  Regular strings are now treated as values (so they
      can be used in cell expressions).  This means you can actually
      start typing expressions and they will actually make sense
      (note that no recalc is yet supported).
      
      The code to do interactive selections is there, but for some
      reason the cursor is not paying much attention to me.
      
      This feature lets you select a cell for an expression if you
      type in a formula in the spreadsheet (just type '=' and use
      the arrow keys to see my buggy code).
