This warning triggers quite a lot when opening
a window while orca is running, which clearly
shows that what it warns about happens in
practice. But fixing it is reentry hell, and
not a battle I'm up for today.
Its been more than a decade since Wayland
has not supported screen coordinates. Clearly
spamming every apps stderr with warnings is
never going to make ATs stop asking for screen
coordinates.
Just give up. Go home
Avoids unaligned accesses when e.g. the key_size is 12 and key_align is
8. We need to round the key size up to 16 to ensure that all keys are
appropriately aligned.
This manifested as a failure in the `gtk:gtk / sorter` unit test on
sparc.

There were two problems here:
First, the code was checking for the abstract
range role, instead of its subclasses.
Second, the code was calling a string value
getter on a number value. Oops.
We can't set the display if we don't have a root,
but the default display is more than good enough
for the tests which otherwise would need to do
quite a bit more setup work to make their test
widgets rooted.
These functions rely on self->accessible_role
being set, and that is only the case for realized
contexts.
In practice, this is not a problem. Contexts are
realized before ATs can get their names or descriptions,
and the inspector realizes contexts too, nowadays.
The only place where this caused a hickup is the
testsuite.
Reimplement the name computation to follow the spec
(https://www.w3.org/TR/accname-1.2) more closely.
Also, unify the functions for name and description,
since their only difference is which property/relation
they use.
Shorten the warnings, and lower some of the
errors to 'not recommended' (where the authoring
guidelines say 'do not label', but aria doesn't
prohibit labels outright).
This is another case of nested control, in this
case it goes two levels deep. Since we already
have this hack, lets use it for all the cases.
This avoids some more complicated workaround.
The group role that we've used before has some
implications of semantic grouping, whereas these
containers are mainly about layout, so use the
generic role instead.
This should not affect the translation to AT-SPI
at all.
The affected containers are: box, grid, centerbox,
scrolledwindow, viewport, windowhandle, aspectframe.
The role of GtkTreeExpander has been changed to
button instead, since it acts as a button.
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.
