	* ms-escher.c (excel_write_MS_O_DRAWING_GROUP) : merge the xp and 2k
	  versions and tidy up.  This will likely need some work for blips

	* ms-chart.c (chart_write_plot) : implement the plot types we can
	  import.
	(chart_write_axis) : provide a default for inverted and
	  log-scale so that we only set them if lookup succeeds.
	(ms_excel_write_chart) : more work.  gnumeric and OOo can
	  now import the basic column charts.  XL does not like the colours
	  and gets the formating wrong, but it can at least read a single
	  chart happilly.

	* ms-excel-write.c (excel_write_chart) : put the spid in the write
	  spot I was off by two bytes.
	(excel_write_autofilter_objs) : Move the container wrapper from here
	(excel_write_objs) : to this new routine so that it can be shared by
	  filters and charts.  We are now close to bit perfect matches to XP.
