a5f8a74ec1 vulkan: Only render minimal region 
It's faster to render once for every rectangle in the clip region than
rendering the outline of the clip region.
Especially because this reduces the time necessary to build up the frame
data.

In widget-factory (where we have 3 rectangles), this leads to a 5x
speedup in the rendering time rendering alone.
Snapshotting time goes from 10ms to ~1ms, which is another huge
improvement.

293248c1d3 gdkvulkan: Track changes per swapchain image 
... and use those in begin_frame() to ensure all of the invalid area
gets invalidated.

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.

573ceb0340 tests: Add a patternspec argument for test creation 
That way, I don't need to recreate all the tests I don't care about.

This is particularly useful when I want to change the size of the
testcase.

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.

599cc995f3 css: Handle repeating gradients with only one offset 
Example:
  repeating-linear-gradient(red 50%, blue 50%)

Those gradients in Firefox draw a solid image of the last color, so do
the same here.

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

texture is not at (0, 0).

71bbd8881f Box: avoid recalc/reassignments, improve var names 
Homogeneous branches repeated the calculation/assignment of the initial
space available to children. This avoids that by shuffling some code.

Perhaps more importantly, in doing that, I ended up with some ambiguous
names, and Company and I realised how vague the pre-existing naming was.
"size" becomes "extra_space", as this is what it represents. Conversely,
"extra" becomes "size_given_to_child" (albeit still given out in two
different ways depending on whether the Box is homogeneous). My hope is
that these sections of code are now somewhat less baffling than before!

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.

b0d5224de5 tests: Use gsk_renderer_render_texture() 
Only keep the version that calls gsk_render_node_draw() if people
specify the --fallback option.

The actual renderer selection works just as for regular GTK. The easiest
way to influence it is setting the GSK_RENDERER environment variable.
