At the moment of launching/activating an application, the
keyboard focus may be on a transient surface that quickly
disappears after activation. If this happens, and the
compositor handles surface destruction before the activated
application gets to reply, the activation request may be
deemed outdated, and the "demands attention" paths be taken.
Peek the toplevel from the focus surface, as that has larger
guarantees to remain valid for the whole duration of the
operation.

We need to inist on the nonuniform access beuing available and that
requires Vulkan 1.2.
Also simplifies the descriptor indexing stuff, because that's all part
of Vulkan 1.2, too.
This function is deprecated, but we should still document it properly.
It appends, not prepends. This is clear enough from its implementation,
but also we have practical experience with WebKit in:

Matthias prefers to avoid the prepend, append, start, and end
terminology altogether.
Texture downloads can be initiated due to the weirdest reasons - and if
they cause a GL context to be changed, it'd be basically unpredictable
when the GL context changes.
An example is the Cairo renderer - if it needs to draw a GL texture, it
will download it.
Now that no longer changes the GL context.
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.
