	* ms-formula-read.c (ms_excel_parse_formula) : add support for
	    FORMULA_PTG_REF_ERR.
	    FORMULA_PTG_AREA_ERR.

	* ms-obj.c (ms_read_OBJ) : add protection against missing virtuals.
	  If the object is a graph read it even if we do not support them in
	  this context (embedded in another object) or if we do not support
	  graphs at all.  This enables us to read embedded graphs without
	  throwing off the rest of the parsing.

	* src/clipboard.c (clipboard_paste_region) : transpose merges too.

	* src/colrow.c (colrow_compute_pixels_from_pts) : ensure that things
	  do not get too small.

	* src/commands.c (cmd_autofill_redo) : clear merges before filling.

	* src/sheet.c (sheet_clear_region) : Add CLEAR_MERGED.

	* src/clipboard.c (clipboard_paste_region) : use sheet_clear_region to
	  remove the merges.

	* src/sheet-autofill.c (fill_item_new) : init the merge sizze to 1x1
	  if we are not merged.  This simplifies logic later.  Remove the
	  'is_merged' flag it was redundant.
	(autofill_create_fill_items) : rename region_count -> region_size
	  it is clearer.  If a cell is merged be smarter about incrementing
	  in a way consistent with what the user sees.
	(sheet_autofill_dir) : ditto.

	* src/workbook-cmd-format.c (sheet_dialog_set_row_height) : honour
	  minima.
	(sheet_dialog_set_column_width) : ditto.

	* src/colrow.c (colrow_compute_pixels_from_pts) : don't let the pixel
	  size shrink below the margin size.
