9b1dcd3872 vulkan: Split out gsk_vulkan_render_pass_append_push_constants() 
Simplifies the code and makes future refactoring easier

c37171f4d6 vulkan: Pass values to push directly 
Don't require a GskVulkanPushConstants there.

c479f93372 vulkan: Add a static assert 
We don't want to make the push constants larger than what the spec
guarantees. And that is 128 bytes, see value for
maxPushConstantsSize in table 55 of
https://registry.khronos.org/vulkan/specs/1.3-extensions/html/vkspec.html#limits-minmax

186e056c56 vulkan: Handle clip properly for offscreens 
This was broken in the last commit.

d8b9c3ae96 vulkan: Track offset in the renderpass 
This avoids emitting lots of push constant updates as most of the
transforms we have are simple translations to adjust drawing for the
next widget.

5de6f12e88 vulkan: Pass scale to offscreens 
Create offscreens with enough pixels for the given scale and ensure
the scale is passed on.

This improves text rendering on offscreens quite a bit.

5422c12577 vulkan: Clean up scale handling 
1. Use a graphene_vec2_t
2. Ensure it's always positive
3. Don't break with fallback

The scale value is nothing more than an indication of how many pixels to
assume per unit of a node.

a55fda0b49 vulkan: Don't store unused matrices 
We can compute it when needed, so do that.

5b93a32f90 vulkan: Remove unneeded argument 
The initial matrix can be computed as needed, so we don't need to
precompute it.

495ee1be3d vulkan: Don't explode without vertex data 
If no buffer has any vertex data (read: if nothing gets drawn), don't
try to allocate a 0 bytes buffer.

8ba5ff98aa vulkan: Don't transform the viewport rect 
We don't want to render the offscreen trnsformed, we want to render it
as-is.

We lose the correct scale factor, but that requires some separate work,
so for now it gets a bit blurry on hidpi.

34f4493c36 vulkan: Make quarks global variables 
I don't want to ensure there's a RenderPass available everywhere and
recreate the quarks in each, I just want to use them.

314923d4b5 vulkan: Split out a function 
We can now create offscreens explicitly.

d2f45dae96 vulkan: offscreens are used as color attachments 
... so set the corresponding flag.

Also name the function "new_for_offscreen()" because thats what this
function is about, "texture" is ambiguous.

af901a10e3 vulkan: Make border shader handle fractional widths 
We were rounding widths properly, make sure we always round up.

3d1a607367 vulkan: Don't round corners when growing rounded rect 
If the corner is set to 0, keep it there.

1be21a33d9 vulkan: Rewrite rounded rectangle to use SDF distance 
We can use this to properly compute distance in scaled situations.
We also now compute coverage with (imperfect) antialiasing.

Benjamin Otte
64bcdb713c vulkan: Start rework on shaders to allow antialiased drawing 
This introduces the rect object and adds a rect_distance() and
rect_coverage() function.

_distance() returns the signed distance tp the rectangle.
_coverage() returns the coverage of a pixel centered at that position.

Note that the pixel size is computed using dFdx/dFdy.

4a868736f9 vulkan: Render whole texture 
When the node bounds were a non-integer size, the texture would get
ceil()ed pixels, but various viewport or scissor computations might
floor() instead, leaving the right/bottom row of pixels untouched.
Make sure those functions ceil(), too.

cfeaa0ac72 renderer: return_if_fail() if the given texture size is 0 
All renderers SEGV currently when that happens.

957fa87fce gsk: Support straight alpha textures 
This is not the optimal way of doing it: we're
reuploading the texture with client-side conversion.
But it fits nicely into our current handling of mipmaps.

We can do better once we use shaders for colorspace
conversions.

0f61c52593 gdk: Simplify gdk_memory_format_gl_format 
Make the callers of this function check for
straight alpha themselves, and only do the
version compatibility check here. This makes
the function usable in contexts where straight
alpha is acceptable.

a4bae6a62d gsk: Use matching memory format 
memory_format_gl_format returns the new memory
format if it made a change, we should not drop
that on the floor.

ef8c835762 gsk: Support swizzle for gray and alpha formats 
Swizzling is needed to display one channel memory formats
as gray etc.

71a231b71d gsk: Stop setting uniforms when we are out of batches 
When the command queue is out of batches, there is
no point in doing further work like allocating uniforms.

This helps us avoid assertions in the uniform code
that we would hit when we run out of uniform space
too.

112fe06323 glrenderer: Remove unused function 
Thanks, macos CI.

(We should have a Fedora clang build.)

9dd83ab354 gsk: Fix a crash 
When we start ignoring batches, we must do it everywhere,
or we may run into assertions. This was triggered by an
enormous text node tree produced by tests/rendernode-create.

2b0ad09423 vulkan: Make projection matrix match GL 
Vulkan has a different initial coordinate system to GL.

GL:
(-1, 1, -1) +------+.
            |`.    | `.
            |  `·--|---·
            |   :  |   :
            +------+.  :
             `. :    `.:
               `·------· (1, -1, 1)

Vulkan:
(-1, -1, 0) +------+.
            |`.    | `.
            |  `·--|---·
            |   :  |   :
            +------+.  :
             `. :    `.:
               `·------· (1, 1, 1)

so adjust the near and far plane we pass to
graphene_matrix_init_ortho() to make it end up with the same
projection as the GL renderer.

d51c92f54d build: Make shaders depend on their includes 
This does not do any proper dependency tracking, it just makes every
shader depend on every include shader.

But that's good enough for now.

1a93efecf3 gsk: Dispose the driver when the display is closed 
This was the intention, but the object data by itself
does not achieve that: We do run dispose on the display
when it is closed, but object data is only cleared in
finalize. So listen to the ::closed signal and remove
the driver ourselves.

Fix up the drivers dispose implementation enough for
that to actually work.
