The protocol spec isn't clear about the relationship
between the capability enum and the uint in the capability
event.
Fix things to use the same relationship as mutter.
This is implemented using a new xdg_toplevel `suspended` state, and is
meant for allowing applications to know when they can stop doing
unnecessary work and thus save power.
In the other backends, the `suspended` state is set at the same time as
`minimized` as it's the closest there is to traditional windowing
systems.
The relevant question here is about details, because we have to choose
if we declare alpha-only formats as having their (nonexistant) color
channels premultiplied or not, so that the code paths using them can do
the right thing.
Because we are premultiplied by default, it makes sense to treat alpha
like that, because then the alpha-only code doesn't need to do
workarounds for straight alpha.
Where this is relevant of course is when expanding the alpha channel
into color channels, where we want to end up with white.
So make sure we do color = alpha there instead of color = 1 like we did
before.
We need them for mask-only textures.
For tiffs, we convert the formats to RGBA (the idea that tiff can save
everything needs to be buried I guess) as tiffs can't do alpha-only.
Basically, memcpy() asap if possible.
This happens a lot in Vulkan, where we gdk_memory_conert() image
data from memory textures straight into the VulkanBuffer.
And usually we support the format.
Have a resource path => vkShaderModule hash table instead of doing fancy
custom objects.
A benefit is that shader modules are now shared between all renderers
and pipelines.
Wait for device to be idle because this function is also called in
window resizes.
And if we destroy old swapchain it also destroy the old VkImages,
those images could be in use by a vulkan render.
This fixes a issue reported in Mesa repository when running
GTK with Xe KMD.

This mapping of stylus evdev input event codes into GDK button numbers
makes gdk/wayland inconsistent with gdk/x11, so depending on the backend
the same button middle-click pastes or right-click pops up menus.
Make the wayland backend consistent with X11, so that a GNOME wayland
session gets these buttons consistently mapped across all kinds of
clients.

Make the display handle the cache, because we only need one.
We store the cache in
$CACHE_DIR/gtk-4.0/vulkan-pipeline-cache/$UUID.$VERSION
so we regenerate caches for each different device (different UUID) and
each different driver version.
We also keep track of the etag of the cache file, so if 2 different
applications update the cache, we can detect that.
Vulkan allows merging caches, so the 2nd app reloads the new cache file
and merges it into its cache before saving.
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)
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.
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.
The GDK_SEAT_CAPABILITY_TABLET_PAD stood awkwardly out of the
ALL value. Even though it's not a keyboard, its focus has more
resemblance to it, so it should be part of this group together
with keyboards.
We were creating the pad device on wp_tablet_pad.done, but
at that time we do not know what tablet it is associated with,
thus we cannot get appropriate vid/pid/name properties for it.
To get that, we need to wait for the pad to enter a surface,
at that time we do know what tablet it is associated with, so
we can get better information about the device.
There are pads that may plausibly "change" tablet between
one .enter event and the next (e.g. Wacom Express Key Remote),
but this situation is highly unlikely. The pad devices created
are thus persistent until that situation happens.
