161ddcfa92 gsk: make render node getters const
This also removes the return if fail macros from these as a good portion
of them didn't have them anyway. I think it's fair to say that access to
these incorrectly is a programmer error.

It significantly reduces the amount of code generated into generally a
movss,ret.

9cec9e4ce2 gsk: Export the glyph serialization privately
We want to use the same serialization in the inspector,
so export this function.

7ea755e206 Add GskGLShaderNode and GskGLShader
A GskGLShader is an abstraction of a GLSL fragment shader that
can produce pixel values given inputs:
 * N (currently max 4) textures
 * Current arguments for the shader uniform
Uniform types are: float,(u)int,bool,vec234)
There is also a builder for the uniform arguments which are
passed around as immutable GBytes in the built form.

A GskGLShaderNode is a render node that renders a GskGLShader inside a
specified rectangular bounds. It renders its child nodes as textures
and passes those as texture arguments to the shader. You also pass it
a uniform arguments object.

2fa9dddea6 gsk: Remember border node uniformity
Lots of border nodes have all the same width and the same color.
Renderers might be able to simplifty that, so keep an extra bit per
border node.

e0323fcdc2 Add get_type() functions for GskRenderNode subclasses
The introspection scanner tries to match a type name with a get_type()
function, in order to correctly identify a type as a class.

If the function is not available, we have two choices:

 - add some special case inside the introspection scanner, similar to
   how GParamSpec subclasses are handled in GObject
 - add a simple get_type() function

The latter is the simplest approach, and we don't need to change that
much, since we still register all render nodes at once.

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.

ba7649b388 inspector: Fix node recording
When attaching renderer-specific data, we need to
make sure that we key it off the renderer that is
in use, and cope with the absence of render data.

This fixes recording nodes in the inspector.

c5af463843 Cache glyph textures in render nodes
This is a quick implementation that avoids many
glyph cache lookups. We keep an array of direct
pointers in the text render node, and throw those
cached pointers away whenever any atlases have
been dropped (since that may invalidate the cached
glyphs).

0d119f81c8 snapshot: Refactor text rendering
The code didn't change, it was just shuffled around to make the

pass through the generic append_node() path.

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.

4f3c7cd48a gsk: Make gsk_text_node_new_with_bounds private
We pulled out the bounds calculation for performance reasons, but the
caller can't know how to properly compute them. Inside gtk+, we can do
that but it's not good enough for public API.

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.

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

b0e8d8483d More work on text nodes
This commit takes several steps towards rendering text
like we want to.

The creation of the cairo surface and texture is moved
to the backend (in GskVulkanRenderer). We add a mask
shader that is used in the next text pipeline to use
the texture as a mask, like cairo_mask_surface does.
There is a separate color text pipeline that uses the
already existing blend shaders to use the texture as
a source, like cairo_paint does.

The text node api is simplified to have just a single
offset, which determines the left end of the text baseline,
like all our other text drawing APIs.

7540702cf0 gsk: Add GskColorMatrixNode
This node essentially implements the feColorMatrix SVG filter. I got the
idea yesterday after looking at the opacity implementation.

It can be used for opacity (not sure if we want to) and to implement a
bunch of the CSS filters.

af917c4ade vulkan: Handle linear gradients
Note: We interpolate premultiplied colors as per the CSS spec. This i
different from Cairo, which interpolates unpremultiplied.

So in testcases with translucent gradients, it's actually Cairo that is
wrong.

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.

colors to transparent for sides with non-matching styles.

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.
