3f224a7165 Add private GtkWidget api for action groups
Similar to the just-added action muxer api for enumerating
action prefixes and for getting the action group for a
prefix.

6bf32999b1 widget: Track when the window scale factor changes and notify
The scale-factor property on the widgets will be notified, and the
scale will change on the style property, causing us to pick up
new css assets.

6c49cd0ea6 action stuff: stop abusing GLib's namespace
Rename our internal GActionMuxer, GActionObserver and GActionObservable
classes and interfaces to have names in our own namespace.

These classes were originally intended for GIO but turned out to be too
special-purpose to be useful there, so we never made them public API but
have just been copying them around (without bothering to properly rename
them).  Now that other people will be copying them out of Gtk, it's even
more important to prevent this namespace abuse from spreading further.

bd4d00918e API: Don't export gtk_widget_preferred_size_and_baseline()
gtk_widget_preferred_size() is only useful if you want to quickly port a
widget from GTK2 sizing code to GTK3 but does not properly work with
height-for-width as used in GTK. So we don't want to encourage people to
use it. In particular we want people to convert to height-for-width
before adding baseline support to their widgets.

d22fd7223c Only handle exposes on native window, propagate to children via draw()
We now consider non-native windows non-opaque, which means any invalid
area in a subwindow will also be invalid all the way up to the nearest
native windows. We take advantage of this by ignoring all expose events
on non-native windows (which typically means just the toplevel) and instead
propagating down the draw() calls to children directly via
gtk_container_propagate_draw.

This is nice as it means we always draw widgets the same way, and it
will let us do some interesting ways in the future.

We also clean up the GtkWidget opacity handling as we can now always
rely on the draing happening via cairo.

We can't really just draw by walking down the widget hierarchy, as
this doesn't get the clipping right (so e.g. widgets doing cairo_paint
may draw outside the expected gdkwindow subarea) nor does it let
us paint window backgrounds.

So, we now do multiple draws for each widget, once for each GdkWindow,
although we still do it on the same base cairo_t that we get for the
toplevel native window. The difference is only the clipping, the rendering
order, and which other widgets we propagate into.

We also collect all the windows of a widget so we can expose them inside
the same opacity group if needed.

NOTE: This change neuters gtk_widget_set_double_buffered for
widgets without native windows. Its impossible to disable
the double buffering in this model.

316d450421 Handle non-baseline supporting subclasses overriding baseline supporting classes
If a subclass (say a child of GtkButton) overrides the non-baseline
size request methods we need to call these, rather than the new
get_height_and_baseline_for_width method.

In order to handle this we make the default for this method to be
NULL, and instead check at runtime which method to call. If any
non-baseline vfunc has changed in a class but the baseline one
hasn't, then we can't use the baseline one.

852cbb62b8 Initial support for baselines
This modifies the size machinery in order to allow baseline support.

We add a new widget vfunc get_preferred_height_and_baseline_for_width
which queries the normal height_for_width (or non-for-width if width
is -1) and additionally returns optional (-1 means "no baseline")
baselines for the minimal and natural heights.

We also add a new gtk_widget_size_allocate_with_baseline() which
baseline-aware containers can use to allocate children with a specific
baseline, either one inherited from the parent, or one introduced due
to requested baseline alignment in the container
itself. size_allocate_with_baseline() works just like a normal size
allocation, except the baseline gets recorded so that the child can
access it via gtk_widget_get_allocated_baseline() when it aligns
itself.

There are also adjust_baseline_request/allocation similar to the
allocation adjustment, and we extend the size request cache to also
store the baselines.

8bdff7a564 sizegroup: Construct the set of sizegroup peers as a hash table
This way we don't need a marker on GtkWidgetParivate that needs to be
unset later, so we have all our data in the same place and can avoid
problems with reentrancy and shenanigans like that.

But the main reason I wrote that is cleaner code.

dd6931d1ba sizegroup: Use _gtk_widget_compute_size_for_orientation()
With this function now available, we can do size computation in 2
ways:
(1) Compute size with size groups
(2) Compute size without size groups

And have (1) use (2) instead of setting flags on widgets. This patch
does exactly that.

d30d56452c GtkWidget: Add gtk_widget_insert_action_group()
This allows adding a GActionGroup with a given name at an arbitrary
point in the widget tree.

This patch also adds an internal _get_action_muxer() API.  Calling this
will create a GActionMuxer associated with the widget.  The parent of
the muxer will be the muxer of the widget's conceptual parent.  For
non-menus, that is the normal parent.  For menus, it is the attach
widget.

In this way, we end up with a hierarchy of GActionMuxer that largely
reflects the hierarchy of GtkWidget, but only in places that the action
context has been requested.  These muxers are the ones on which the
inserted actions groups are installed.

A following patch will add a user of this API.

9f4bfff1b0 gtk: Add a way to do event capture
This patch adds a capture phase to GTK+'s event propagation
model. Events are first propagated from the toplevel (or the
grab widget, if a grab is in place) down to the target widget
 and then back up. The second phase is using the existing
::event signal, the new capture phase is using a private
API instead of a public signal for now.

This mechanism can be used in many places where we currently
have to prevent child widgets from getting events by putting
an input-only window over them. It will also be used to implement
kinetic scrolling in subsequent patches.

http://bugzilla.gnome.org/show_bug.cgi?id=641836

We automatically request more motion events in behalf of
the original widget if it listens to motion hints. So
the capturing widget doesn't need to handle such
implementation details.

We are not making event capture part of the public API for 3.4,
which is why there is no ::captured-event signal.

4a18fe7ef2 Introduce gtk_window_get/set_attached_to()
gtk_window_get/set_attached_to() is a new API that allows for windows to
be attached to a GtkWidget.
The attachment is a logical binding between the toplevel window and the
widget that generated it; this kind of information is currently used to
propagate style information from the widget to the window, but is also
useful e.g. for accessibility.

38b5c8cf45 Cache heights-for-range-of-widths instead of height for every width.
This patch optimizes window resizes by assuming that if a widget
has the same height at a width of 50 as with a width of 150, the
height for width 100 will also be the same.

The patch also further optimizes the cache allocator, now there
are 2 pointer arrays of up to a maximum of 5 requests, the arrays
will only be allocated if a request is ever made in that orientation
and the array will be sparse until each request is made (i.e. if a
label can only wrap to 3 lines, there will only be 3 out of a
possible 5 SizeRequest structures allocated to cache it).
