ac333d712d snapshot: Make append_node_internal transfer-full
There is only one case where we do *not* directly unref the node again
after calling this.

bd113aa85c transform: Redo querying API
Make the API expect a tranform of the proper category instead of
doing the check ourselves and returning TRUE/FALSE.

The benefit is that the mai use case is switch (transform->category)
statements and in those we know the category and don't need to check
TRUE/FALSE.

Using the wrong matrix will now cause a g_warning().

b391aea2b3 widget: Make transform a GskTransform
This concludes pushing transforms down into GskTransform.

What's remaining is potentially pushing it further into the renderers.

51fac44ba5 snapshot: Introduce transform APIs
Instead of gtk_snapshot_offset(), provide a full set of functions
kept in sync with GtkTransform APIs.

On top of that, add gtk_snapshot_save() and gtk_snapshot_restore()
mirroring cairo_save()/restore() that allow saving a snapshot's
transform state.

4a293aa762 snapshot: Store an actual GtkTransform
Instead of just tracking 2 integer translate_x/y coordinates, tracka a
full GtkTransform.

When creating actual nodes, if the transform is simple enough, just
create the node in a way that makes use of the transform. If the
node, can't represent the transform, just push a transform node instead
and automatically pop that node with the next gtk_snapshot_pop() call.

6a4bf2b993 gsk: Remove offset nodes
They were a neat idea while they lasted. But now, it's time for
categorized transform nodes, where matrices with
GSK_MATRIX_CATEGORY_2D_TRANSLATE are the exact replacement.

Renderers have not been adapted for this purpose, so they (continue to)
run slow paths.

c44c44ee25 css: Pass boxes to the render functions
Instead of style + rect_of_one_box, pass the new GtkCssBoxes object.
This has the nice side effect that when drawing background + border +
outline, we only compute all the boxes we need once.

cf1526cca6 snapshot: Add gtk_snapshot_from_parent
Most of the time, the GtkSnapshot objects we create while snapshotting
widgets don't end up containing all that many nodes or states in their
respective node or state stack. This undermines the amortized allocation
behavior of the G(Ptr)Array we use for the stacks. So instead, use the
(until now unused) parent_snapshot GtkSnapshot* passed to
gtk_widget_create_render_node and reuse its node and state stack.

We do not avoid allocating a new GtkSnapshot object, but we do avoid
allocating a ton of G(Ptr)Array objects and we also avoid realloc'ing
their storage.

c02bc22cc5 Use aligned allocators for GtkSnapshot
Any data that is later fed to graphene must be
allocated with proper alignment, if graphene
uses SSE2 or GCC vector instructions.

This adds custom array code (a streamlined copy
of GArray with all unnecessary bells and whistles removed),
which is then used for the state_stack instead of GArray.

There's also a runtime check for the size of GtkSnapshotState
itself being a multiple of 16. If that is not so, any array
elements past the 0th element will lose alignment.
There are probably struct attributes that can
make GtkSnapshotState always have size that is a multiple
of 16, but we'll burn that bridge if we cross it.

622a150bb4 snapshot: merge container nodes
A container node inside another container node doesn't make a lot of
sense, we can instead just use the parent container node and add the
child container node's children to it directly.

2db43edbd6 snapshot: Don't handle clip anymore
If widgets want to clip things, they now need to do it themselves.

By not taking care of clip, we avoid the need to track clip. And by not
tracking clip, we can avoid all unnecessary cache invalidations that we
were doing for render nodes whenever the clip changed.

And when you are scrolling, the clip changes *a lot*.

47ea3a9452 snapshot: Don't cause invalid reads
1. Pass clip rectangles to gtk_snapshot_push_state() that point into
   the state array.
2. g_array_set_size(len+1) the state array
3. Make that function realloc() the state array.
4. The clip rectangle now points into invalid memory
5. Use the clip array

This patch fixes things by moving step 5 to before step 2.

ffc7b2bb0a snapshot: Allow passing the bounds of the created paintable
This allows being more specific about the size.
It's useful in particular when the resulting render nodes might be
too small for the size, not only when they are too large. For the
latter case, using a clip node would be enough.

It also requires adding a clip node when rendering the resulting
paintable, but that should be optimized out by GtkSnapshot when not
necessary.

29111a16d4 widget: Cache the render node
This requires a bunch of refactorings:

1. Don't pass the current clip region to gtk_widget_snapshot()
   so we don't create full widget contents
3. Have a widget->priv->draw_needed that we invalidate on every
   queue_draw() call and set on every snapshot()
2. In queue_draw(), walk the widget chain to invalidate the
   render nodes of all parents
