	* gtk/gtktreeview.c (gtk_tree_view_class_init): Replace the
	expander_height and expander_width properties with a single
	property, expander_size.
	(gtk_tree_view_init): Set the tab_offset to expander_size
	plus some padding.
	(gtk_tree_view_unrealize): Remove the expand/collapse
	timeout if it exists.
	(coords_are_over_arrow): Fix a small bug.
	(gtk_tree_view_motion_draw_column_motion_arrow): Use
	expander_size.
	(gtk_tree_view_draw_focus): Use "treeview" instead of
	"add-mode" as detail when drawing the focus.
	(gtk_tree_view_bin_expose): Use "treeview-drop-indicator"
	instead of "add-mode" as detail when drawing the focus.
	(gtk_tree_view_deleted): If we have a node currently being
	expanded or collapsed, remove the timeout and set the node
	to NULL.
	(gtk_tree_view_queue_draw_arrow): New function that just
	redraws the arrow of a node.
	(gtk_tree_view_draw_arrow): Use expander_size instead of
	expander_width/expander_height, also pass a different
	expander_style to gtk_paint_expander depending on the
	state of the node being drawn.
	(expand_collapse_timeout): New function for expanding
	or collapsing a node depending on the previous state.
	(gtk_tree_view_real_expand_row): Add timeout and set
	correct state for node being expanded.
	(gtk_tree_view_real_collapse_row): Add timeout and set
	correct state for node being collapsed.

	* gtk/gtktreeprivate.h (struct _GtkTreeViewPrivate): Add
	information about the node currently being expanded or
	collapsed, and also a timeout id.

	* gtk/gtkstyle.h (struct _GtkStyleClass): Replace is_open
	with expander_style for draw_expander.

	* gtk/gtkstyle.c (gtk_draw_expander): Replace is_open with
	expander_style.
	(create_expander_affine): New function for creating an
	expander affine.
	(apply_affine_on_point): New function for applying an
	affine to a point.
	(gtk_default_draw_expander): Modified to take expander_style
	instead of is_open, and to draw the rectangle rotated differently
	depending on the expander style.
	(gtk_paint_expander): Replace is_open with expander_style.

	* gtk/gtkrbtree.h: Add expander states to GtkRBNodeColor.

	* gtk/gtkenums.h: Add expander style enum.
