2954417335 cssnode: Change the way we start animations 
We now have a flag for "invalidate animations", use that to restart
animations and decide if we want to start transitions.

172f345d01 cssnode: Return NULL as frame clock when animations are disabled 
This is a crude hack, but it works.

FIXME: Hook it up to the GtkSettings so that we properly update when the
setting changes.

dbe5058b86 cssnode: Add API to query the timestamp 
... and pass it to the API that computes new styles.

A special timestamp of 0 means "please don't animate" and is used when
no frame clock is available for a node.

16b8972bee cssnode: Change get_style_provider() vfunc 
Instead of always returning a provider, allow the vfunc to return NULL
to mane "use same provider as parent". This allows a bunch of
optimizations.

13fd368781 cssnode: Change vfunc 
This is mainly an attempt to merge the update_style() and validte()
vfuncs. Code is not there yet, but that's the idea.

Also, gtk_css_node_set_style() should not be public. And this gets
closer to that goal, too.

75b633ae08 cssnode: Only pass a boolean for parent changes 
Nobody cares what changed in the parent, so don't track it.

e95985da26 cssstyle: Remove unused optimization 
After measuring it, I realized the optimization never triggers for
Adwaita and rarely ever triggers for simple themes. So it is not
useful to keep it around.

2694545468 cssnode: Add visibility concept 
This allows hiding nodes of invisible widgets.
And that in turn makes sure :nth-child() works as expected.

ee91fb71ca box: Use CSS nodes instead of widget paths 
This is a very simple patch that causes a bunch of overhead. But it
works.

310f9f40da cssnode: Add hackery to allow bypassing widget paths 
If we know the parent's get_path_for_child() implementation is safe to
be used with GtkCssNode because it doesn't do anything special, we do
that. Unfortunately that requires whitelisting vfuncs because the vfunc
is public API so anyone can override it.

2a5194b635 cssnode: Make widget node not copy the path 
Instead, use gtk_widget_get_path() which makes GtkWidget cache the path.
This is a temporary solution until we can get rid of widget paths.

This increases memory usage quite noticably.

020f3f11c8 cssnode: Handle invalidate queueing differently 
Instead of directly requesting the layout phase, register a tick
callback. This is what the docs suggest for animations and it's what we
need for the next commit.

cdd964a3af cssnode: Change way invalidation is handled 
Have a queue_validate() vfunc and a dequeue_validate() vfunc that are
called only on root nodes so they can queue a validation on their frame
clocks.

219e52f7e1 cssnode: Automatically recreate style on get_style() call 
When the style is invalid, redo it.

Make this a vfunc, so the widget nodes can opt out.

e2f6d4db43 cssnode: Split into 3 objects

- GtkCssPathNode
  for style contexts using a GtkWidgetPath
- GtkCssTransientNode
