	* gal/widgets/e-reflow.c (reflow_columns): enable this function to
	reflow the view from a particular column onward.  This is useful
	if you have a huge model and the only changes are happening at the
	end (as is normally the case if you're appending to a large
	model.)
	(item_changed): calculate the height of the changed item here, so
	we aren't doing it as we reflow the model.  For now, reflow the
	entire model.  Further optimization can be done here.
	(item_removed): new function.  remove the item and reflow from the
	column that contained it.
	(items_inserted): calculate the heights of the new items, and
	calculate the lowest numbered column containing one of the
	inserted items.  reflow from there.
	(model_changed): calculate the heights of everything here.
	(comparison_changed): new function, clear the sorter and reflow.
	(disconnect_model): disconnect comparison_changed and
	model_item_removed.
	(connect_model): connect comparison_changed and
	model_item_removed.
	(adjustment_changed): use queue_incarnate here, instead of forcing
	the reflow model to incarnate as we scroll.  Not sure if this is
	actually the right solution, but it does make the scrollbar more
	responsive at the cost of redraw speed.

	* gal/widgets/e-reflow.h (struct _EReflow): add slots for the new
	signal ids, as well as "reflow_from_column".

	* gal/widgets/e-reflow-model.c (e_reflow_model_class_init): create
	the comparison_changed and model_item_removed signals.
	(e_reflow_model_comparison_changed): new function, emit the
	comparison_changed signal.
	(e_reflow_model_item_removed): new function, emit the
	model_item_removed signal.

	* gal/widgets/e-reflow-model.h: add comparison_changed and
	model_item_removed signals.
