css: Break the selector tree into many

Since we can only match one name, doing a hash
by matcher name lets us quickly discard most
initial selectors, and having much smaller trees.

We can apply the same idea for style classes,
as well, by looking up a tree for each class.

Comparing the number of gtk_css_selector_match() calls
while moving the pointer outside the window, I see:

Before:
65773 selector matches (12863 positive)

After:
32704 selector matches (12278 positive)

So this cuts the numer of selectors we need to check
roughly in half, at the cost of a handful of hash table
lookups.

-/* Menus
- *
- * There are several widgets involved in displaying menus. The
- * GtkMenuBar widget is a menu bar, which normally appears horizontally
- * at the top of an application, but can also be layed out vertically.
- * The GtkMenu widget is the actual menu that pops up. Both GtkMenuBar
- * and GtkMenu are subclasses of GtkMenuShell; a GtkMenuShell contains
- * menu items (GtkMenuItem). Each menu item contains text and/or images
- * and can be selected by the user.
- *
- * There are several kinds of menu item, including plain GtkMenuItem,
- * GtkCheckMenuItem which can be checked/unchecked, GtkRadioMenuItem
- * which is a check menu item that's in a mutually exclusive group,
- * GtkSeparatorMenuItem which is a separator bar, GtkTearoffMenuItem
- * which allows a GtkMenu to be torn off, and GtkImageMenuItem which
- * can place a GtkImage or other widget next to the menu text.
- *
- * A GtkMenuItem can have a submenu, which is simply a GtkMenu to pop
- * up when the menu item is selected. Typically, all menu items in a menu bar
- * have submenus.

-HANDLING WIDGET STYLES
-======================
-
-
-A widget gets created with a default style.
-The global default style can be affected by gtk_widget_set_default_style()
-and can be queried by gtk_widget_get_default_style().
-The initial style that is assigned to a widget as default style upon
-creation can be affected by wrapping the widget's creation as follows:
-gtk_widget_push_style (my_style);
-widget = gtk_type_new (gtk_button_get_type ());
-gtk_widget_pop_style ();
-
-There are certain functions to affect widget styles after a widget's
-creation:
-
-gtk_widget_set_style ()
-  Save the default style and set a user style.
-  This will override a previously set user style or
-  previously set rc styles.
-
-gtk_widget_reset_rc_styles ()
-  Descends through a widget hierarchy and sets the rc style
-  on all widgets that don't have a user style set.
-
-gtk_widget_ensure_style ()
-  Ensure that the widget either has a user style set, or an rc lookup
-  has been performed.
-
-gtk_rc_get_style ()
-  Return an rc style for a widget if there is one.
-
-gtk_widget_set_name ()
-  Change widget name, and perform a new rc lookup if no user style
-  is set.
-
-gtk_widget_realize ()
-  Besides realizing the widget this function will:
-  - perform an rc lookup if necessary,
-  - attach a widget's style.
-
-gtk_widget_get_style ()
-  Return a widgets style, this function will perform an rc lookup
-  if necessary.
-
-gtk_widget_set_parent ()
-  This function will perform rc lookups recursively for all widgets
-  that do not have a user style set.
-
-gtk_style_copy ()
-  This function can be used to copy a widget's style.
-  The style can subsequently be changed (e.g., by modifications to the
-  red/green/blue values of a certain color) and then be applied to the
-  widget via gtk_widget_set_style().
-
-
-GtkWidget::style_set
-  This signal will be emitted for a widget once its style changes with
-  an additional argument previous_style which will hold the widget->style
-  value from a previous emission.
-  The initial emission of this signal is guaranteed to happen prior
-  to any GtkWidget::size_request emission, and will have the previous_style
-  argument set to NULL.
-  The GtkWidgetClass implements a default handler for this signal that
-  will set the widget's window's background of widgets that provide their
-  own windows according to the new style.
-  Derived widgets need to override this default handler, if:
-  - their size requisition depends on the current style.
-    (e.g., on the style's fonts)
-  - they set the background of widget->window to something other than.
-    style->bg. (e.g., GtkListItem)
-  - the widget provides windows other than widget->window.
-  - the widget has any other stored dependencies on the style.
-                   
-
-
-Flag indications:
-
-!GTK_RC_STYLE && !GTK_USER_STYLE:
-  The widget has its default style set, no rc lookup has been
-  performed, the widget has not been size requested yet and is
-  therefore not yet realized.
-
-GTK_USER_STYLE:
-  GTK_RC_STYLE is not set.
-  The widget has a user style assigned, and its default style has been
-  saved.
-
-GTK_RC_STYLE:
-  GTK_USER_STYLE is not set.
-  If the widget has a saved default style, it has been assigned an
-  rc style. If the widget does not have a saved default style, it still
-  has its default style but an rc lookup has already been performed.

-Notes about the inner workings of the widget system of GTK
-==========================================================
-
-This file contains some notes as to how the widget system does
-and should work. It consists of three parts:
-
- I) A description of the meaning of the various flags
-
- II) A list of invariants about the states of the widgets. 
-    (Throughout this document, we refer to the states of the
-     widgets by referring to the flags for GtkWidget)
-
- III) Some notes about the ways that a widget changes states
-
- IV) A list of responsibilities of various widget signals when
-    the states change.
-
-Any action necessary to maintain the invariants in II which is not
-explicitly mentioned in IV), is the responsibility of the core GTK
-code, which is roughly defined as:
-
-  gtkobject.c
-  gtkwidget.c
-  gtkcontainer.c
-  gtkmain.c
-  gtksignal.c
-
-Section II is mostly of interest to those maintaining GTK, the
-other sections may also be interesting to people writing
-new widgets.
-
-Main outline:
-	- Owen Taylor <owt1@cornell.edu>
-	  1998/02/03
-
-Flag descriptions:
-	- Tim Janik <timj@gimp.org>
-	  1998/02/04
-
-I. Flags
---------
-
-GtkObject:
-
-GTK_DESTROYED:
-	This flagged is set for a GtkObject right before its
-	destruction code is executed. Its main use is the
-	prevention of multiple destruction invocations.
-	
-GTK_FLOATING:
-	This flag reflects the fact that the holder of the
-	initial reference count is unknown. Refer to refcounting.txt
-	for further details.
-
-GTK_RESERVED_1:
-GTK_RESERVED_2:
-	Reserved flags.
-
-
-GtkWidget, public flags:
-
-GTK_TOPLEVEL:
-	Widgets without a real parent, as there are GtkWindows and
-	GtkMenus have this flag set throughout their lifetime.
-	Toplevel widgets always contain their own GdkSurface.
-	
-GTK_NO_WINDOW:
-	This flag is indicative for a widget that does not provide
-	its own GdkSurface. Visible action (e.g. drawing) is performed
-	on the parent's GdkSurface.
-
-GTK_REALIZED:
-	Set by gtk_widget_realize, unset by gtk_widget_unrealize.
-	Relies on ((widget->parent && widget->parent->window)
-	           || GTK_WIDGET_TOPLEVEL (widget));
-	Means: widget has an associated GdkSurface (XWindow).
-
-GTK_MAPPED:
-	Set by gtk_widget_map, unset by gtk_widget_unmap.
-	May only be set if GTK_WIDGET_REALIZED (widget).
-	Means: gdk_surface_show() has been called on the widgets window(s).
-
-GTK_VISIBLE:
-	Set by gtk_widget_show.
-	Implies that a widget will be flagged GTK_MAPPED as soon as its
-	parent is mapped.
-!GTK_VISIBLE:
-	Set by gtk_widget_hide.
-	Implies that a widget is not onscreen, therefore !GTK_MAPPED.
-
-GTK_CHILD_VISIBLE
-        Set by gtk_widget_set_child_visible, and if FALSE indicates that 
-        the widget should not be mapped even if the parent is mapped
-        and visible. Containers like GtkNotebook use this flag.
-        A private flag, not a public flag, so if you need to check
-        this flag, you should call gtk_widget_get_child_visible().
-        (Should be very rarely necessary.)
-
-GTK_SENSITIVE:
-	Set and unset by gtk_widget_set_sensitive.
-	The sensitivity of a widget determines whether it will receive
-	certain events (e.g. button or key presses). One premise for
-	the widgets sensitivity is to have GTK_SENSITIVE set.
-
-GTK_PARENT_SENSITIVE:
-	Set and unset by gtk_widget_set_sensitive operations on the
-	parents of the widget.
-	This is the second premise for the widgets sensitivity. Once
-	it has GTK_SENSITIVE and GTK_PARENT_SENSITIVE set, its state is
-	effectively sensitive. This is expressed (and can be examined) by
-	the GTK_WIDGET_IS_SENSITIVE macro.
-
-GTK_CAN_FOCUS:
-	There are no directly corresponding functions for setting/unsetting
-	this flag, but it can be affected by the GtkWidget::has_focus argument
-	via gtk_widget_set_arg.
-	This flag determines whether a widget is able to handle focus grabs.
-
-GTK_HAS_FOCUS:
-	This flag will be set by gtk_widget_grab_focus for widgets that also
-	have GTK_CAN_FOCUS set. The flag will be unset once another widget
-	grabs the focus.
-	
-GTK_CAN_DEFAULT:
-GTK_HAS_DEFAULT:
-	These two flags are mostly equal in functionality to their *_FOCUS
-	counterparts, but for the default widget.
-
-GTK_HAS_GRAB:
-	Set by gtk_grab_add, unset by gtk_grab_remove.
-	Means: widget is in the grab_widgets stack, and will be the preferred
-	one for receiving events other than ones of cosmetic value.
-
-GTK_BASIC:
-	The GTK_BASIC flag is an attempt at making a distinction
-	between widgets that handle user input e.g. key/button presses
-	and those that don't. Subsequent parent<->child relation ships
-	of non `basic' widgets should be avoided. The checking for
-	this is currently not properly enforced in the code. For
-	example GtkButton is a non `basic' widget, that will therefore
-	disallow to act as a container for another GtkButton. Now the
-	gnit is, one can add a GtkHBox (which is a `basic' widget) to
-	the first button, and put the second into the box.
-
-GTK_RESERVED_3:
-
-GTK_RC_STYLE:
-	This flag indicates that its style has been looked up through
-	the rc mechanism. It does not imply that the widget actually
-	had a style defined through the rc mechanism.
-
-
-GtkWidget, private flags:
-
-GTK_USER_STYLE:
-	A widget is flagged to have a user style, once gtk_widget_set_style
-	has been invoked for it. The use of this flag is to tell widgets
-	which share a global user style from the ones which got a certain
-	style assign from outside the toolkit.
-	
-GTK_RESIZE_PENDING:
-	First, this is only valid for GtkContainers.
-	[some of the code should move to gtkcontainer.c therefore]
-	Relies on GTK_WIDGET_REALIZED(widget)
-	[this is not really enforced throughout the code, but should
-	 be. it only requires a few checks for GTK_WIDGET_REALIZED and
-	 minor changes to gtk_widget_unrealize, we can then remove the check
-	 in gtk_widget_real_destroy]
-	Means: there is an idle handler waiting for the container to
-	resize it.
-
-GTK_RESIZE_NEEDED:
-	Relies on GTK_WIDGET_REALIZED(widget)
-	[this is not really enforced throughout the code, but should
-	 be. once this is done special checking in gtk_widget_real_destroy
-	 can be avoided]
-	Means: a widget has been added to the resize_widgets list of
-	its _toplevel_ container (keep this in mind for GtkViewport).
-	Remark: this flag is also used internally by gtkwindow.c during
-	the evaluation of resizing worthy widgets.
-
-GTK_LEAVE_PENDING:
-	A widget is flagged as such if there is a leave_notify event
-	pending for it. It will receive this event regardless of a grab
-	through another widget or its current sensitivity.
-	[this should be made relying on GTK_REALIZED]
-
-GTK_HAS_SHAPE_MASK:
-	Set by gtk_widget_shape_combine_mask if a widget got a shape mask
-	assigned (making use of the X11 shaped window extension).
-
-GTK_IN_REPARENT:
-	During the act of reparentation widgets which are already
-	realized and will be added to an already realized parent need
-	to have this flag set to prevent natural unrealization on the
-	process of getting unparented.
-
-GTK_NEED_REQUEST:
-	This flag is set if the widget doesn't have an up to date 
-	requisition. If this flag is set, we must actually emit ::size-request
-        when gtk_widget_size_request() is called. Otherwise, we can
-        simply widget->requisition. We keep track of this all the time
-        however, widgets with this flag set are only added to the resize 
-	queue if they are viewable.
-
-GTK_NEED_ALLOCATION:
-	This flag is set if the widget doesn't have an up to date 
-	allocation. If this flag is set, we must actually emit ::size-allocate
-        when gtk_widget_size_allocate() is called, even if the new allocation
-        is the same as the current allocation.
- 
-Related Macros:
-
-GTK_WIDGET_DRAWABLE:
-	This macro examines whether a widget is flagged as GTK_WIDGET_VISIBLE
-	and GTK_WIDGET_MAPPED.
-	Means: it _makes sense_ to draw in a widgets window.
-
-GTK_WIDGET_IS_SENSITIVE:
-	This macro tells the real sensitivity state of a widget. It returns
-	whether both the widget and all its parents are in sensitive state.
-
-
-II. Invariants:
----------------
-
-This section describes various constraints on the states of 
-the widget:
-
-In the following
-
-  A => B     means  if A is true, than B is true
-  A <=> B    means  A is true, if and only if B is true
-                    (equivalent to A => B and A <= B)
-
-
-1)  GTK_WIDGET_DESTROYED (widget) => !GTK_WIDGET_REALIZED (widget)
-                                  => !GTK_WIDGET_VISIBLE (widget)
-[ The latter is not currently in place, but it should be ] 
- 
-2) GTK_WIDGET_MAPPED (widget) => GTK_WIDGET_REALIZED (widget)
-
-3) if GTK_WIDGET_TOPLEVEL (widget):
-   GTK_WIDGET_VISIBLE (widget) <=> GTK_WIDGET_MAPPED (widget)
-
-4) if !GTK_WIDGET_TOPLEVEL (widget):
-  widget->parent && GTK_WIDGET_REALIZED (widget->parent) <=>
-     GTK_WIDGET_REALIZED (widget)
-
-5) if !GTK_WIDGET_TOPLEVEL (widget):
-
-   GTK_WIDGET_MAPPED (widget) => GTK_WIDGET_VISIBLE (widget)
-                              => GTK_WIDGET_CHILD_VISIBLE (widget)
-                              => GTK_WIDGET_REALIZED (widget)
-
-   widget->parent && GTK_WIDGET_MAPPED (widget->parent) && 
-     GTK_WIDGET_VISIBLE (widget) && GTK_WIDGET_CHILD_VISIBLE 
-       <=> GTK_WIDGET_MAPPED (widget)
-
-Note:, the definition
-
-[  GTK_WIDGET_DRAWABLE = GTK_WIDGET_VISIBLE && GTK_WIDGET_MAPPED
-   is made in gtkwidget.h, but by 3) and 5), 
-     
-      GTK_WIDGET_MAPPED => GTK_WIDGET_VISIBLE
-]
-
-6) GTK_REDRAW_PENDING => GTK_WIDGET_REALIZED
-   GTK_RESIZE_PENDING =>         "
-   GTK_LEAVE_PENDING  =>         "
-   GTK_RESIZE_NEEDED  =>         "
-
-III. How states are changed:
-----------------------------
-
-How can the user control the state of a widget:
------------------------------------------------
-
-(In the following, set flag means set the flag, do appropriate
-actions, and enforce above invariants) 
-
-gtk_widget_show: 
- if !GTK_DESTROYED sets GTK_VISIBLE
-
-gtk_widget_hide:
- if !GTK_VISIBLE for widget
-
-gtk_widget_destroy:
- sets GTK_DESTROYED
- For a top-level widget
-
-gtk_widget_realize:
- if !GTK_DESTROYED sets GTK_REALIZED
-- Calling gtk_widget_realize when the widget is not a descendant
-  of a toplevel is an ERROR.
-
-gtk_container_add (container, widget) [ and container-specific variants ]
- Sets widget->parent 
-
-gtk_container_remove (container, widget)
- unsets widget->parent
-
-gtk_widget_reparent (widget, new_parent)
- Equivalent to removing widget from old parent and adding it to
- the new parent, except that the widget will not be temporarily 
- unrealized if both the old parent and the new parent are realized.
-
-
-gtk_widget_unrealize
-gtk_widget_map
-gtk_widget_unmap
-
-These functions are not meant to be used by applications - they
-are used only by GTK and widgets to enforce invariants on the
-state.
-
-When The X window corresponding to a GTK window is destroyed:
--------------------------------------------------------------
-
-gtk_widget_destroy is called (as above).
-
-
-
-IV. Responsibilities of widgets
---------------------------------
-
-Adding to a container
----------------------
-
-When a widget is added to a container, the container:
-
-  1) calls gtk_widget_set_parent_surface (widget, window) if 
-     the widget is being added to something other than container->window
-  2) calls gtk_widget_set_parent (widget, container)
-
-Removing from a container
--------------------------
-
-When a widget is removed to a container, the container:
-
-  1) Calls gtk_widget_unparent (widget)
-  2) Queues a resize.
-
-Notes:
-
- gtk_widget_unparent unrealizes the widget except in the 
-   special case GTK_IN_REPARENT is set.
-
-
-At widget creation
-------------------
-
-Widgets are created in an unrealized state. 
-
- 1) The widget should allocate and initialize needed data structures
-
-
-The Realize signal
-------------------
-
-When a widget receives the "realize" signal it should:
-
- NO_WINDOW widgets: (probably OK to use default handler)
-
-  1) set the realized flag
-  2) set widget->window
-      widget->window = gtk_widget_get_parent_surface (widget);
-      g_object_ref (widget->window);
-  3) attach the widget's style
-
-  widget->style = gtk_style_attach (widget->style, widget->window);
-
- widget with window(s)
-
-  1) set the REALIZED flag
-  2) create windows with the parent obtained from
-      gtk_widget_get_parent_surface (widget);
-  3) attach the widget's style
-  4) set the background color for the new window based on the style
-
-The Map signal
---------------
-
-  1) Set the MAPPED flag
-  2) If the widget has any windows, gdk_surface_show those windows
-  3) call gtk_widget_map for all child widgets that are 
-     VISIBLE, CHILD_VISIBLE and !MAPPED. (A widget will only
-     be !CHILD_VISIBLE if the container set it that way, so
-     most containers will not have to check this.)
-  3) Do any other functions related to putting the widget onscreen.
-     (for instance, showing extra popup windows...)
-
-The Unmap signal
-----------------
-
-When a widget receives the unmap signal, it must:
-
- 1) If the widget has a window, gdk_surface_hide that window, 
- 2) If the widget does not have a window, unmap all child widgets
- 3) Do any other functions related to taking the widget offscreen
-     (for instance, removing popup windows...)
- 4) Unset GTK_MAPPED
-
-
-The Unrealize signal
---------------------
-
-When a widget receives the unrealize signal, it must
-
- 1) For any windows other than widget->window do:
-
-    gdk_surface_set_user_data (window, NULL);
-    gdk_surface_destroy (window);
-
- 2) Call the parent's unrealize handler
-
-
-The Widget class unrealize handler will take care of unrealizing
-all children if necessary. [should this be made consistent with
-unmap???]
-
-
-The Destroy Signal
-------------------
-
-Commentary:
-
-  The destroy signal probably shouldn't exist at all. A widget
-  should merely be unrealized and removed from its parent
-  when the user calls gtk_widget_destroy or a GDK_DESTROY event
-  is received. However, a large body of code depends on
-  getting a definitive signal when a widget goes away.
-
-  That could be put in the finalization step, but, especially
-  with language bindings, the cleanup step may need to refer
-  back to the widget. (To use gtk_widget_get_data, for instance)
-  If it does so via a pointer in a closure (natural for
-  Scheme, or Perl), then the finalization procedure will never
-  be called. 
-
-  Also, if we made that the finalization step, we would have
-  to propagate the GDK_DESTROY event in any case, since it is
-  at that point at which user-visible actions need to be taken.
-
-
-When a widget receives the destroy signal, it must:
-
-  1) If the widget "owns" any widgets other than its child
-     widgets, (for instance popup windows) it should
-     call gtk_widget_destroy () for them.
-
-  2) Call the parent class's destroy handler.
-
-
-The "destroy" signal will only be received once. A widget
-will never receive any other signals after the destroy
-signal (but see the section on "Finalize" below)
-
-The widget must handle calls to all publically accessible
-functions in an innocuous manner even after a "destroy"
-signal. (A widget can assume that it will not be realized 
-after a "destroy" signal is received, which may simplify
-handling this requirement)
-
-
-The Finalize Pseudo-signal
---------------------------
-
-The finalize pseudo-signal is received after all references
-to the widget have been removed. The finalize callback
-cannot make any GTK calls with the widget as a parameter.
-
-1) Free any memory allocated by the widget. (But _not_
-   the widget structure itself.
-
-2) Call the parent class's finalize signal
-
-
-A note on chaining "destroy" signals and finalize signals:
----------------------------------------------------------
-
-This is done by code like:
-
-  if (GTK_OBJECT_CLASS (parent_class)->destroy)
-    (* GTK_OBJECT_CLASS (parent_class)->destroy) (object);
-
-It may not be completely obvious why this works. Note
-that parent_class is a static variable on a per-class
-basis. So say: we have
-
-  GtkFoo <- GtkBar <- GtkWidget <-GtkObject
-
-And that Foo, Widget, and Object all have destructors, but
-not Bar.
-
-Then gtk_foo_destroy will call gtk_widget_destroy (because
-it was not overridden in the Bar class structure) and
-gtk_widget_destroy will call gtk_object_destroy because
-the parent_class variable referenced by gtk_foo_destroy is the 
-static variable in gtkwidget.c: GtkObjectClass.
