9b83116fcb snapshot: Export gtk_snapshot_append_layout()
This is the equivalent snapshot function to pango_cairo_show_layout().

Not to be confused with gtk_snapshot_render_layout(), which is the
equivalent to gtk_render_layout().

1cfa88ed91 snapshot: Remove renderer
Now that there's no longer a need to keep the renderer around for Cairo
rendering, don't do that then.

ea84e974e6 snapshot: Turn into GObject
This makes GdkSnapshot the base class for GtkSnapshot and hopefully
stops confusing bindings.

C code should see no difference to before.

e23f641e49 GtkSnapshot: Implement the builder pattern
Make GtkSnapshot a refcounted boxed type, and add
public API that follows the builder pattern described
here: https://blogs.gnome.org/otte/2018/02/03/builders/

4c150d8eb5 The big versioning cleanup
Remove all the old 2.x and 3.x version annotations.
GTK+ 4 is a new start, and from the perspective of a
GTK+ 4 developer all these APIs have been around since
the beginning.

19871cfd68 snapshot: Add & use API for linear gradient nodes
This way, we can also clip the created node bounds to the current clip
of the GtkSnapshot. This works as long as we don't modify the start and
end points, and happens all the time while rendering.

ca3c23662c GskTexture => GdkTexture
We want this thing to replace GdkPixbuf, so it has to live in GDK.

d6be42203b Add gtk_snapshot_push_blur()
This function is similar to the other push functions.
This one uses the newly created blur node.

6055028c96 snapshot: Rename append APIs
Instead of having gtk_snapshot_append_foo_node(), just have
gtk_snapshot_append_foo(). Nobody needs to know that this internally

b58de2d16c snapshot: Redo pop() API
gtk_snapshot_pop() => removed
gtk_snapshot_pop_and_append() => gtk_snapshot_pop()

So now there is no way to get a rendernode out of the snapshotting API
until you gtk_snapshot_finish().

d9b0685b49 Add gtk_snapshot_push_cross_fade()
... and use it.

The function is a bit awkward because it requires 2 calls to
gtk_snapshot_pop(), but once you accept that, it's very convenient to
use, as can be seen by the 2 implementations.

c00f8dce9f GtkSnapshot: Always use int for the translation
We already take ints when setting the translation, so it can't
currently take any other values. Additionally, I was seeing large
costs in int -> double -> int for the rects in
gtk_snapshot_clips_rect(), as all callers really are ints (widget
allocations) and the clip region is int-based.

This change completely cleared a 2% rectangle_init_from_graphene from
the profile and is likely to have nice performance effects elsewhere
too.

2480e0d575 gsk: Add GskShadowNode

This requires moving even more shadow renering code into GSK, but so be
it. At least the "shadows not implemented" warning is now gone!

1137483d15 snapshot: Work on pushing and popping again
It is now possible to call push() subfunctions for simple container
nodes with just a single child. So you can for example
gtk_snapshot_push_clip() a clip region that all the nodes that get
appended later will then obey.

gtk_snapshot_pop() will then not return a container node, but a clip
node containing the container node (and similar for the transform
example).

This is implemented internally by providing a "collect function" when
pushing that is called when popping to collects all the accumulated
nodes and combine them into the single node that gets returned.

To simplify things even more, gtk_snapshot_pop_and_append() has been
added, which pops the currently pushed node and appends it to the
parent.

The icon rendering code has been converted to this approach.

c258ee403a snapshot: Make gtk_snapshot_get_renderer() private
Public API doesn't need to be concerned with renderers. Worst case, they
can use NULL instead of the actual renderer.

02131d590e snapshot: Change how gtk_snapshot_push/pop works
Instead of appending a container node and adding the nodes to it as they
come in, we now collect the nodes until gtk_snapshot_pop() is called and
then hand them out in a container node.

The caller of gtk_snapshot_push() is then responsible for doing whatever
he wants with the created node.

Another addigion is the keep_coordinates flag to gtk_snapshot_push()
which allows callers to keep the current offset and clip region or
discard it. Discarding is useful when doing transforms, keeping it is
useful when inserting effect nodes (like the ones I'm about to add).

67fb129ed7 gsk: gsk_render_node_set_transform() => GskTransformNode
Instead of having a setter for the transform, have a GskTransformNode.

Most of the oprations that GTK does do not require a transform, so it
doesn't make sense to have it as a primary attribute.

Also, changing the transform requires updating the uniforms of the GL
renderer, so we're happy if we can avoid that.

3eb7c4719b gsk: Remove gsk_render_node_set_bounds()
gsk_render_node_get_bounds() still exists and is computed via vfunc
call:
- containers dynamically compute the bounds from their children
- surface and texture nodes get bounds passed on construction

8830a1a1ad gtk: Remove gtk_snapshot_append()

d1b80a6baa gtk: Don't push cairo nodes
We want to split nodes into containers and nodes that do actual drawing.
So pushing nodes that do drawing is exactly the wrong thing.

Also fix up GtkPopover. There's no need for it to push anything.

d1fec79c00 snapshot: Completely reengineer API
We now try to emulate cairo_t:

We keep a stack of nodes via push/pop and a transform matrix.

So whenever a new node is added to the snapshot, we transform it
by the current transform matrix and append it to the current node.
