cadf6a9d3c cssnode: Add gtk_css_node_invalidate_style_provider()
This function not just invalidates the current node, but also all
children.

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.

c0f6e746a0 cssnode: Implement a way to properly track invalidations
See the comment in gtkcssnodeprivate.h for how this works.

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.

9b73b39f9a cssnode: Treat transient nodes as invisible nodes
Making transient nodes invisible allows us to remove special cases
without any bad side effects and they continue working just like they
did before.

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.

507016cafc cssnode: Refactor node tree modification code
This allows adding more API for it.

It also includes code that tracks modifications and invalidates siblings
and their positions whenever nodes get added or removed.

... and use that matcher by default - ie for transient nodes.

2bf7bdd651 cssmatcher: Allow widget path matcher to take a node declaration
The node declaration has the same functionality as
gtk_css_node_declaration_add_to_widget_path(). So instead of using that
function on a path, you can use the original path and the declaration in
a matcher.

630f0f199e cssnode: Split out a function
So far the vfunc is kinda quirky (the path argument is an out argument
for something you have to free when you're done with the matcher), but
  I'm about to change that.

28043f0a92 cssnode: Refactor invalidation propagation

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.

a589f98821 cssnode: Implement refcounting
The parent refs the child, so gtk_css_node_set_parent() adds/removes a
reference.

We should probably refactor this so that we name the function
parent.add(node) instead of node.set_parent(parent) - makes the
refcounting more clear.

e2f6d4db43 cssnode: Split into 3 objects
- GtkCssWidgetNode
  for style contexts owned by a widget
- GtkCssPathNode
  for style contexts using a GtkWidgetPath
- GtkCssTransientNode

be596f3967 stylecontext: Split out GtkCssNode into own file
The functionality of it is supposed to grow, so better put it in a
custom file early.

This is just a naive split so far, the next patches will split things
further.
