def700739d Use a single compilation symbol
We use a compilation symbol in our build to allow the inclusion of
specific headers while building GTK, to avoid the need to include only
the global header.

Each namespace has its own compilation symbol because we used to have
different libraries, and strict symbol visibility between libraries;
now that we have a single library, and we can use private symbols across
namespaces while building GTK, we should have a single compilation
symbol, and simplify the build rules.

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.

8755d884f3 Remove a lot of Since annotations
4.0 will represent a clean epoch. We don't want to have
lots of noise in the docs about 2.x or 3.x.

353ad30b12 rendernode: Fix serializing
Adding the offset node broke serialization in 2 ways:

1. We store the enum value in the node, so make sure to not change it
   for existing values
2. The offset node was missing in the deserialization lookup table

ce743f28a1 rendernode: Add an offset node
This is a special case of the transform node that does a 2D translation.

The implementation in the Vulkan and GL renderers is crude and just does
the same as the transform node.

Nothing uses that node yet.

481b5d1b89 Partially revert GskTexture → GdkTexture rename
Excessive use of sed when moving GskTexture to GDK; the GskTextureNode
should still live under the GSK namespace.

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

4975aa7920 Add a render node for text
This is just a wrapper around a PangoGlyphString + PangoFont.
Basically, the arguments that are passed to pango_renderer_draw_glyphs.

b993acfe2c gsk: Add GskRepeatNode
Also add gtk_snapshot_push_repeat() and use that to draw backgrounds.

With that change, CSS background snapshots are created without Cairo
nodes.

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.

fcc1f554d6 gsk: Add GskInsetShadowNode
And again lots of shadow code gets copied to GSK. But we're now almost
at a stage where widget-factory does not use cairo nodes anymore.

2480e0d575 gsk: Add GskShadowNode
... and make the icon rendering code use it.

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

75b76af221 gsk: Add GskBorderNode
The node draws a solid CSS border, which can be used to cover everything
but dashed and dotted borders (double, groove, inset, ...).

For different border styles, we overlay multiple nodes and set their
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.

7afdd3fdb5 Initial implementation of GSK rendering pipeline
GSK is conceptually split into two scene graphs:

 * a simple rendering tree of operations
 * a complex set of logical layers

The latter is built on the former, and adds convenience and high level
API for application developers.

The lower layer, though, is what gets transformed into the rendering
pipeline, as it's simple and thus can be transformed into appropriate
rendering commands with minimal state changes.

The lower layer is also suitable for reuse from more complex higher
layers, like the CSS machinery in GTK, without necessarily port those
layers to the GSK high level API.

This lower layer is based on GskRenderNode instances, which represent
the tree of rendering operations; and a GskRenderer instance, which
takes the render nodes and submits them (after potentially reordering
and transforming them to a more appropriate representation) to the
underlying graphic system.
