It's necessary now that we use storage buffers for gradients:
[ VUID-VkDescriptorSetLayoutBindingFlagsCreateInfo-descriptorBindingStorageBufferUpdateAfterBind-03008 ] Object 0: handle = 0x1e72d70, type = VK_OBJECT_TYPE_DEVICE; | MessageID = 0x943cc552 | vkCreateDescriptorSetLayout(): pBindings[0] can't have VK_DESCRIPTOR_BINDING_UPDATE_AFTER_BIND_BIT for VK_DESCRIPTOR_TYPE_STORAGE_BUFFER since descriptorBindingStorageBufferUpdateAfterBind is not enabled. The Vulkan spec states: If VkPhysicalDeviceDescriptorIndexingFeatures::descriptorBindingStorageBufferUpdateAfterBind is not enabled, all bindings with descriptor type VK_DESCRIPTOR_TYPE_STORAGE_BUFFER must not use VK_DESCRIPTOR_BINDING_UPDATE_AFTER_BIND_BIT (https://www.khronos.org/registry/vulkan/specs/1.3-extensions/html/vkspec.html#VUID-VkDescriptorSetLayoutBindingFlagsCreateInfo-descriptorBindingStorageBufferUpdateAfterBind-03008)
If a node has a higher depth, pick the RGBA format that has that depth
as the texture format we're renderig to with render_texture().
Support for adapting the swapchain is not part of this.
When a GdkMemoryFormat isn't supported, pick close formats that have a
higher chance of being supported.
Make sure this works recursively and the whole loop always ends up at
R8G8B8A8_UNORM because that one is mandatory.
Roughly, follow these rules:
1. Drop the unpremultiplied
2. Expand channels to include all of RGBA
3. pick swizzle that is RGBA
4. pick next largest depth
5. pick R8G8B8A8_UNORM
This way, we unify the code paths for memory access to textures.
We also technically gain the ability to modify images, though I have no
use case for this.
That way, the offscreen can create images of different types.
Its not used in this commit, but will come in handy when we want to
support high bit depth.
Pretty much copy what GL does and just use the default display to create
GPU-related resources without the need for a display.
This also adds gdk_display_create_vulkan_context() but I've
kept it private because the Vulkan API is generally considered in flux,
in particular with our pending attempts to redo how renderers work.
Fixes a bug introduced in d1135f9e3c.
Luckily the buffer was large enough that all my testing didn't catch it
because it took a few minutes to overflow.
The result of calling update_property needs
to be that the property is marked as set
afterward, even if the value we pass happens
to match the default value.
After this change, scrollbars have value-now
show up as zero in the accessiblity page of
the inspector, even when that matches the lower
bound.
Test included.
Fixes: #5886
Replace gdk_memory_format_prefers_high_depth with the more generic
gdk_memory_format_get_depth() that returns the depth of the individual
channels.
Also make the GL renderer use that to pick the generic F16 format
instead of immediately going for F32 when uploading textures.
Special-case nested buttons in our name computation,
since it is hard to reconcile all the a11y attributes
being on the wrapper, but the focus ending up on the
button inside.
This is a pragmatic approach that works. The only
downside is that the wrapper and the button end up
with the same name+description, but at least orca
seems to only read the focus elements' ones.
This reverts commit 343b9d246f.
Unfortunately, this makes it so that the focus ends up on
the 'generic' accessible, not the one with the label, and
orca remains quiet.
This reverts commit 5ec0b07baf.

Make the internal toggle button generic, so that
the a11y checker doesn't complain about it not
having a label. And mark the icons in the popup
as presentational.
Make the color button itself take the button role,
and make the internal toggle button just be generic.
This solves the problem that labelled-by relations
that are set up in ui files via mnemonics point at
the toplevel, not the toggle button.
