	* src/sheet-control-gui.c (resize_pane_pos) : handle motion in frozen
	  areas.
	(sheet_control_gui_new) : use a blank label as a space rather than a
	  scrollbar.  Emmanuel's idea seems more consistent with frozen panes
	  than reseting the pane.
	(set_resize_pane_pos) : new utility to calculate the desired pane
	  position and block the signal.
	(resize_pane_finish) : renamed from cb_resize_pane_finish to be more
	  consistent.  Round the pane position to the col/row bound using
	  set_resize_pane_pos.
	(scg_set_panes) : position the resize panes.  Change the behavior not
	  to short circuit if the freeze status is unchanged.  This seems safe
	  and makes sue that set_resize_pane_pos is called.
