	They fell with their faces to the foe.

	They shall grow not old, as we that are left grow old,
	Age shall not weary them, nor the years condemn.
	At the going down of the sun, and in the morning,
	We will remember them.

	Lest we forget.

	* src/xml-io.c: adapted code to the new XML tree format, however
	  to compile you need to update your libxml from the CVS tree too.
	  Not a definite solution I'm thinking about a more general API
	  for XML tree values encoding/decoding. I modified the endoding
	  format but backward compatibility should be maintained.

	* src/sheet.c (canvas_bar_realized): 
	* src/gnumeric-sheet.c (gnumeric_sheet_realize): Neat X hack:  set
	the window backing pixmap to NULL, so that the window does not get
	cleared when it receives an exposure event.  It will just leave
	whatever bits were on the window when the expose happened.  This
	allows us to avoid flicker.  *** MIGUEL, LOOK AT THIS ***

	* src/gnumeric-sheet.c (gnumeric_sheet_make_cell_visible): Fixed
	width/height confusion (cut&paste bug).

	* src/sheet.c (new_canvas_bar): Set outrageously big scrolling
	limits.  This has to be fixed to use the real sheet's dimensions.
	(sheet_new): Use correct table expansion parameters.

	scrolling region, for now.  This needs to be fixed.

	with or without GMP.
