d701a89281 Turn GskRenderNode into a derivable type
Language bindings—especially ones based on introspection—cannot deal
with custom type hiearchies. Luckily for us, GType has a derivable type
with low overhead: GTypeInstance.

By turning GskRenderNode into a GTypeInstance, and creating derived
types for each class of node, we can provide an introspectable API to
our non-C API consumers, with no functional change to the C API itself.

69016825aa render node: Optimize type checks
The GSK_IS_RENDER_NODE macro is a bit silly,
and not worth having in g_return_if_fail checks
in trivial getters.

20d1bc2ccc rendernodeparser: Skip root node when it's a container
When printing, behave the same way as when parsing:
Magically skip a container node if there is one - just like the
parser magically creates a container node to hold all the nodes
it parses.

01a7c7a8b2 Parse render nodes from text files
Instead of the previous approach using GVariant, this new approach uses
human-readable text files as the serialization format for render nodes.

The format is a custom one, but it is inspired by QML and conforms to
the CSS syntax. Because of that, we can use the CSS machinery from GTK
to parse it, and in particular share code to parse properties that GTK's
CSS machinery also supports, such as colors.

This commit breaks all existing usages of node files - such as the
testsuite and various test tools - they will be fixed in further
commits.

c48be6ef96 Revert "Add aligned allocator functions to GSK"
This reverts commit 8e74eb382f.

This code is not necessary. It worked around a bug in graphene where
graphene was requiring stricter alignment than glib allocators could
guarantee.

a394a86151 Use aligned allocators for GskRenderNode
Any data that is later fed to graphene must be
allocated with proper alignment, if graphene
uses SSE2 or GCC vector instructions.

b49dccb86d rendernode: Remove gsk_render_node_set_name()
And of course, gsk_render_node_get_name() is gone, too.
The replacement is of course debug nodes.

As a side effect, GskRenderNode is now *really* immutable.

271820b677 rendernode: Add gsk_render_node_diff()
... and gsk_render_node_can_diff(). Those are vfuncs to compute a region
containing all the pixels that differ between the two nodes.

This is just the plumbing that chains into node classes. No node
implements it yet.

391727bd0d GdkWindow -> GdkSurface initial type rename
This renames the GdkWindow class and related classes (impl, backend
subclasses) to surface. Additionally it renames related types:
GdkWindowAttr, GdkWindowPaint, GdkWindowWindowClass, GdkWindowType,
GdkWindowTypeHint, GdkWindowHints, GdkWindowState, GdkWindowEdge

This is an automatic conversion using the below commands:

git sed -f g GdkWindowWindowClass GdkSurfaceSurfaceClass

git sed -f g GdkWindow GdkSurface
git sed -f g "gdk_window\([ _\(\),;]\|$\)" "gdk_surface\1" # Avoid hitting gdk_windowing
git sed -f g "GDK_WINDOW\([ _\(]\|$\)" "GDK_SURFACE\1" # Avoid hitting GDK_WINDOWING
git sed "GDK_\([A-Z]*\)IS_WINDOW\([_ (]\|$\)" "GDK_\1IS_SURFACE\2"
git sed GDK_TYPE_WINDOW GDK_TYPE_SURFACE
git sed -f g GdkPointerWindowInfo GdkPointerSurfaceInfo

git sed -f g "BROADWAY_WINDOW" "BROADWAY_SURFACE"
git sed -f g "broadway_window" "broadway_surface"
git sed -f g "BroadwayWindow" "BroadwaySurface"
git sed -f g "WAYLAND_WINDOW" "WAYLAND_SURFACE"
git sed -f g "wayland_window" "wayland_surface"
git sed -f g "WaylandWindow" "WaylandSurface"
git sed -f g "X11_WINDOW" "X11_SURFACE"
git sed -f g "x11_window" "x11_surface"
git sed -f g "X11Window" "X11Surface"
git sed -f g "WIN32_WINDOW" "WIN32_SURFACE"
git sed -f g "win32_window" "win32_surface"
git sed -f g "Win32Window" "Win32Surface"
git sed -f g "QUARTZ_WINDOW" "QUARTZ_SURFACE"
git sed -f g "quartz_window" "quartz_surface"

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.

c56419818f gsk: make logging per-renderer
Add a setter for per-renderer debug flags, and use
them where possible. Some places don't have easy access
to a renderer, so this is not complete.
Also, use g_message instead of g_print throughout.

52b1cd40d1 gsk: Remove gsk_render_node_set_scaling_filters()
This is a leftover from the very early rendernode that we forgot to delete.

This can be seen by the fact that it is settable on an immutable object.

230d27b079 GskRenderNode: Use C99 flexible arrays to avoid extra allocation
Instead of a separate allocation for any arrays in the render node
we allocate these as part of the render node itself, using C99
flexible arrays.

This leads to less allocations, which is nice, but the major reason
for this is that it allows us to change the allocation scheme further
in the future. For instance, we want to do stack-like allocation so
that all the render-nodes for an entire frame are allocated in one
(or a few) chunks.

22110ef5a4 gsk: Add bounds member to RenderNode
Instead of constantly recalculating this (especially recursively for
parents!) we do it only on construction, because everything is
immutable anyway. Also, most nodes had a bounds already and can
use the new parent member instead.

We also do direct access to the node bounds rather than calling
gsk_render_node_get_bounds in various places, which means
we do less copying.

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.

4d376c80f3 gsk: Remove gsk_render_node_get_size()
In the brave new world of refactored render nodes, this function doesn't
really make any sense anymore. We could turn it into a vfunc, but I
don't think it's useful.

Especially because even in the brave old world, this function was
causing a vastl overallocation of nodes when the GL renderer needed render
targets.
