40d7092f4a widget: Queue a draw when we need to
The code in gtk_widget_real_css_changed assumes that
queue_resize > queue_allocate > queue_draw, but the
second one is not really true. These days, we happily
keep reusing the same render node even when the child
allocation is changed.

So, if a css change has flags that tell us we should
redraw, we need to queue a draw, otherwise we might
end up reusing an outdated render node.

This fixes spinners staying visible when they stop
spinning, despite the theme setting their opacity
to 0.

cab1dcb696 gdk: Conflate GDK devices
Make GdkEvents hold a single GdkDevice. This device is closer to
the logical device conceptually, although it must be sufficient for
device checks (i.e. GdkInputSource), which makes it similar to the
physical devices.

Make the logical devices have a more accurate GdkInputSource where
needed, and conflate the event devices altogether.

c63087a563 Remove ATK
To build a better world sometimes means having to tear the old one down.
        -- Alexander Pierce, "Captain America: The Winter Soldier"

ATK served us well for nearly 20 years, but the world has changed, and
GTK has changed with it. Now ATK is mostly a hindrance towards improving
the accessibility stack:

 - it maps to a very specific implementation, AT-SPI, which is Linux and
   Unix specific
 - it requires implementing the same functionality in three different
   layers of the stack: AT-SPI, ATK, and GTK
 - only GTK uses it; every other Linux and Unix toolkit and application
   talks to AT-SPI directly, including assistive technologies

Sadly, we cannot incrementally port GTK to a new accessibility stack;
since ATK insulates us entirely from the underlying implementation, we
cannot replace it piecemeal. Instead, we're going to remove everything
and then incrementally build on a clean slate:

 - add an "accessible" interface, implemented by GTK objects directly,
   which describe the accessible role and state changes for every UI
   element
 - add an "assistive technology context" to proxy a native accessibility
   API, and assign it to every widget
 - implement the AT context depending on the platform

f401b05e7b gtkwidget: Avoid poking surfaces and events in gtk_widget_list_devices()
This got stuck in ancient times when widgets were windowed, so the devices
in a window to know the devices in that widget would pan out. We do only
want here the devices that are inside the widget, not spread over the
surface, so rewrite this helper function to poke the toplevel foci, and
look they are contained inside the widget.

We expect widgets to use their own derived GtkWidgetAccessible type,

6b096e5c5b Make tooltip properties idiomatic
The tooltip handling in GtkWidget is "special":

 - the string is stored inside the qdata instead of the private
   instance data
 - the accessors call g_object_set() and g_object_get(), and the
   logic is all inside the property implementation, instead of
   being the other way around
 - the getters return a copy of the string
 - the setters don't really notify all the involved properties

The GtkWidgetAccessible uses the (escaped) tooltip text as a source for
the accessible object description, which means it has to store the
tooltip inside the object qdata, and update its copy at construction and
property notification time.

We can simplify this whole circus by making the tooltip properties (text
and markup) more idiomatic:

 - notify all side-effect properties
 - return a constant string from the getter
 - if tooltip-text is set:
   - store the text as is
   - escape the markup and store it separately for the markup getter
 - if tooltip-markup is set:
   - store the markup as is
   - parse the markup and store it separately for the text getter

The part of the testtooltips interactive test that checks that the
getters are doing the right thing is now part of the gtk testsuite, so
we ensure we don't regress in behaviour.

d3e0a1f68c Avoid quadratic slowdown in gtk_widget_add()
If you add a widget to a parent, this will invalidate the css nodes
for parent/siblings. Afterwards, if the parent is mapped, we will
realize the new child. This calls gtk_widget_update_alpha() which
needs the css opacity, so it revalidates the css.

Thus, for each widget_add (while visible) will trigger a full
revalidation of each sibling. If you add N children to a parent that
leads to O(N^2) revalidations.

To demo this I changed gtk-demo to always double the count
(independent of the fps) and print the time it took. Here is the
results (after a bit):

Setting fishbowl count=256 took 3,4 msec
Setting fishbowl count=512 took 10,1 msec
Setting fishbowl count=1024 took 34,1 msec
Setting fishbowl count=2048 took 126,3 msec
Setting fishbowl count=4096 took 480,3 msec
Setting fishbowl count=8192 took 1892,7 msec
Setting fishbowl count=16384 took 7751,0 msec
Setting fishbowl count=32768 took 38097,7 msec
Setting fishbowl count=65536 took 191987,7 msec

To fix this we drop gtk_widget_update_alpha() and just
calculate it when needed (which is only in a single place).
It was really only necessary because we previously set
the alpha on the surface.

With this fix the above becomes:

Setting fishbowl count=256 took 1,0 msec
Setting fishbowl count=512 took 1,9 msec
Setting fishbowl count=1024 took 3,7 msec
Setting fishbowl count=2048 took 7,4 msec
Setting fishbowl count=4096 took 18,1 msec
Setting fishbowl count=8192 took 31,0 msec
Setting fishbowl count=16384 took 66,3 msec
Setting fishbowl count=32768 took 126,7 msec
Setting fishbowl count=65536 took 244,6 msec
Setting fishbowl count=131072 took 492,2 msec
Setting fishbowl count=262144 took 984,3 msec

56e590bd31 widget: Drop the ::size-allocate signal
This signal is mainly used for bad things, and we
don't want to emit signals during layout if we can
avoid it.

If you are subclassing, you should either use a
layout manager or override the size_allocate vfunc.

If you are using a GtkDrawingArea or GtkGLArea,
use their ::resize signals to learn about size
changes.

cb94c7d69e Explicitly update widget a11y bounds when allocating
The a11y machinery is using signal subscription to get notified of size
changes and notify listeners in turn. This is suboptimal for a couple of
reasons:

 - if something connects to the GtkWidget::size-allocate signal we need
   to emit it; currently, we have an optimization in place that will
   skip the signal emission if there are no handlers, and it would be
   nice to go through the fast path
 - the accessibility implementation is part of GTK, and should not go
   through additional hoops like any out-of-tree API consumer

Alexander Larsson
c6104fe7fd Drop parent->realized => child->realized invariant
We already dropped this invariant in gtk_widget_verify_invariants()
because it was not true in all cases. Also, it is not really useful
these days as we extended what it means to be a "child" to also
include widgets in different toplevels.

For example, a popup in a popup button need not be realized just
because the button is in a realized window. The main invariants
we want are:

 * Parent is realized before child
 * Widget is realized before it is mapped

This sounds like its not a huge deal, but in fact it is a massive win
for things like menus, because when we go between menus in a menubar
each switch between two open menus involves a lot of intermingled
crossing events to different surfaces and for each of these the
tooltip window of the toplevel gets assigned to the new surface.  This
shouldn't be a huge deal, as the tooltip window is not even visible,
but due to the realized invariant it get re-realized each time it gets
re-assigned.

f28aa1ba02 Restructure the GdkEvent type hierarchy
GdkEvent has been a "I-can't-believe-this-is-not-OOP" type for ages,
using a union of sub-types. This has always been problematic when it
comes to implementing accessor functions: either you get generic API
that takes a GdkEvent and uses a massive switch() to determine which
event types have the data you're looking for; or you create namespaced
accessors, but break language bindings horribly, as boxed types cannot
have derived types.

The recent conversion of GskRenderNode (which had similar issues) to
GTypeInstance, and the fact that GdkEvent is now a completely opaque
type, provide us with the chance of moving GdkEvent to GTypeInstance,
and have sub-types for GdkEvent.

The change from boxed type to GTypeInstance is pretty small, all things
considered, but ends up cascading to a larger commit, as we still have
backends and code in GTK trying to access GdkEvent structures directly.
Additionally, the naming of the public getter functions requires
renaming all the data structures to conform to the namespace/type-name
pattern.

ccac404f28 widget: fix class private data usage to be _init() safe
Before this commit, adding GtkWidgetAction to class private data would
require copying the actions to each subclass as they were built or
modified. This was convenient in that it is a sort of "copy on write"
semantic.

However, due to the way that GTypeInstance works with base _init()
functions, the "g_class" pointer in GTypeInstance is updated as each
_init() function is called. That means you cannot access the subclasses
class private data, but only the parent class private data.

If instead we use a singly linked list of GtkWidgetAction, each subclass
has their own "head" yet all subclasses share the tail of the
GtkWidgetAction chain.

This creates one bit of complexity though. You need a stable way to know
which "bit" is the "enabled" bit of the action so we can track enabled
GAction state. That is easily solved by calculating the distance to the
end of the chain for a given action so that base classes sort ahead of
subclasses. Since the parent class always knows its parent's actions, the
position is stable.

A new dynamic bitarray helper also helps us avoid allocations in all the
current cases (up to 64 actions per widget) and dynamically switches to
malloc if that is to ever be exceeded.

Managed scope so far is unimplemented.

This is supposed to be used to replace accelerators and mnemonics.

This is a very barebones controller that currently does nothing but

And because we have bindings on every widget (Yes, a GtkGrid has a
keybinding - 2 in fact), we need that controller everywhere.

5e099e2606 Remove incorrect rename-to annotations
The `rename-to` annotation is used to "shadow" a symbol with another
one, which means both symbols need to exist. It can't be used to rename
a symbol to something else.

a411959c91 droptarget: Redo
This is a huge reorganization of GtkDropTarget. I did not know how to
split this up, so it's unfortunately all one commit.

Highlights:

- Split GtkDropTarget into GtkDropTarget and GtkDropTargetAsync
  GtkDropTarget is the simple one that only works with GTypes and offers
  a synchronous interface.
  GtkDropTargetAsync retains the full old functionality and allows
  handling mime types.

- Drop events are handled differently
  Instead of picking a single drop target and sending all DND events to
  it, every event is sent to every drop target. The first one to handle
  the event gets to call gdk_drop_status(), further handlers do not
  interact with the GdkDrop.
  Of course, for the ultimate GDK_DROP_STARTING event, only the first
  one to accept the drop gets to handle it.
  This allows stacking DND event controllers that aren't necessarily
  interested in handling the event or that might decide later to drop
  it.

- Port all widgets to either of those
  Both have a somewhat changed API due to the new event handling.
  For the ones who should use the sync version, lots of cleanup was
  involved to operate on a sync API.

6f73a750a7 widget: Simplify adjust_allocation()
And in particular, only do it if the widget doesn't use ALIGN_FILL.

This avoids lots of measuring in the common case and speeds up
size_allocate() by about 25%.

And because size_allocate() is the bottleneck in the fishbowl, this also
gets ~25% more fishies.

612ba7ec15 widget: Don't check for natives
It's the native's job to request a 1px x 1px size, not the job of
gtk_widget_size_allocate()

Also saves 10% of size_allocate() time because checking for an interface
is really expensive.
