3c8518dce3 gsk: Add missing Mozilla copyright header 
I stole one of their shader functions, and if I steal, I might as well
do it right.

5017c3be65 gsk: Insist on ordered color stops 
I don't want to sort them later for the shader preparation, so make
sure they come in ordered.

3a79b17309 vulkan: Fix coordinate setup 
This makes rendering textures work when the top left of the rendered
texture is not at (0, 0).

b30225e67c vulkan: We use VK_FORMAT_B8G8R8A8_UNORM 
... not SRGB. SRGB messes up alpha compositing, GdkRGBA and everything
else.

aa0ec774bf vulkan: Add proof-of-concept clip implementation 
We can now clip to cicular rounded rectangles when drawing colors.

81c487b841 vulkan: Fold clip into push constants 
As a side effect, the clipping data is now available inside shaders.

Not that any shader would use them yet, but they could!

18b65a2378 vulkan: Change handling of push constants 
Instead of storing the wire format, store the true structs and only
convert to the wire format when needed.

b11b7dfb1a gsk: Add debug category for fallbacks 
... and use it for the cases in Vulkan where we fall back to Cairo.

2bca24c455 gsk: Add GskVulkanClip 
This is now tracking the clips added by the clip nodes.
If any particular node can't deal with a clip, it falls back to Cairo
rendering. But if it can, it will render it directly.

89d38ae93f vulkan: Try combining draw calls 
This gives a 5-7% speedup in the case where we're just drawing N colors
and nothing else. So it;s not tremendously useful, but noticeable.

node...

087ea8e531 gsk: Warn on cairo errors during gsk_render_node_draw() 
It's the same warning we use inside GTK for when stuff weirdly goes
wrong.

08f9a6078b gsk: Include config.h 
The more you know:
Not including config.h causes the public API implemented in this file to
not be exported in the resulting library.

2d2209859e gsk: Rename to gsk_texture_download_surface()

actual bytes.

373e08d6d4 gsk: Add gsk_renderer_render_texture() 
... and implement it for the Cairo renderer.

It's an API that instructs a renderer to render to a texture.
So far this is mostly meant to be used for testing, but I could imagine
it being useful for rendering DND icons.

d2622d93ad gsk: Don't overdraw with transparent 
That code doesn't do anything.

And what the code should be doing (clearing the abckground) isn't
necessary as cairo drawing is guaranteed to clear the surface.

814b66e1a8 gsk: Remove nonexisting functions 
The function was removed when gsk_render_node_draw() was and
gsk_renderer_realize() was refactored respectively.

c88d279416 gsk: Add gsk_render_node_serialize/deserialize() 
This does a conversion to/from GBytes and is intended for writing tests.

It's really crude but it works.
And that probably means Alex will (ab)use it for broadway.

3a38bc9bf7 gsk: Remove spread member from GskShadow 
I had originally thought I'd use GskShadow for box-shadow, but didn't in
the end.

So now it's only used for text-shadow and icon-shadow, and those don't
have a spread.

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.

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.

1760e0d3f3 vulkan: Get rid of color in push constants

b04eecf860 vulkan: Pass color rects in instance data 
This way, we don't need push constants or per-vertex data, we can render
colored rectangles completely via instance data.
