The ngl renderer has good support for fractional scaling, so we
can enable this by default now.
If you are using the gl renderer, you can disable fractional
scaling with the
GDK_DEBUG=gl-no-fractional
environment variable.
When a toplevel is focused programmatically and there is no
underlying seat, we cannot attempt to focus it with no
focus to be obtained, nor serials serials to use.

In GLES, BGRA is still done by GL_EXT_texture_format_BGRA8888 which is
an extension that is older than GLES 2.0.
And back then, internal formats had to be specified unsized. And when
that was changed with GLES3, nobody updated the extension.
However, on OpenGL, this extension doesn't exist, and internal formats
need to be sized.
So let's use different internal formats depending on GL version.
Fixes#6333
Whether or not switches include shapes to indicate their ON/OFF
state is currently controlled by the stylesheet (in particular
the HighContrast style).
However there are use cases for both using the HighContrast style
without shapes, and for using shapes with the regular stylesheet,
so follow the newly added "show-status-shapes" setting instead.

For tablet tools if we have NULL cursor, we use the default cursor
instead. This provides us with a tablet cursor when an application never
sets the cursor.
However, on proximity out when we clear said cursor we also
need to toggle off cursor_is_default, otherwise on the next proximity in
we assume we already have a cursor and never update it again.
This leads to an invisible cursor over GTK application when the tablet
tool is brought into proximity over the widget (but not when moving into
the widget from the outside).
Closes: #6312
If shaders don't support nonuniform indexing, we emulate it via if/else
ladders (or switch ladders) which get inlined by the GLSL compiles and
massively blow up the code.
And that makes compilation of the shaders take minutes and results in
shader code that isn't necessarily faster.
So we disable it on GL entirely and on Vulkan if the required features
aren't available.
As it's only an optimization and does not fall back to Cairo anymore,
this should be fine.
gdk_texture_save_to_png_bytes() cannot fail, so ensure that it doesn't.
Testsuite has been updated to check for this case.
Note that we do not load the PNG file that we generate here.
Loading is a lot more scary than saving after all.
If people want to load oversized PNG files, they should use a real PNG
loader.
This is using the Vulkan renderer.
It also allows claiming support for all the formats that only Vulkan
supports, but that neither GL nor native mmap can handle.
I did it because it unifies the code.
But it also gains the benefit of being debuggable because it can
now be turned off via GDK_VULKAN_SKIP=incremental-present
This ensures both that we signal a semaphore for a dmabuf when we export
an image and that we import semaphores for dmabufs and wait on them.
Fixes Vulkan node-editor displaying the Vulkan renderer in the sidebar.
This code does not add a downloader, so we do not claim support for all
the new formats.
It just queries the formats. But this can be used to import dmabufs
directly into the Vulkaan renderer.
use it to collect the optional features we are interested in and turn
them on only if available.
For now we add the dmabuf features, but we don't use them yet.
According to EXT_color_buffer_half_float it should be renderable, but it
fails to glGenerateMipmap() with Mesa 23.3 so just pretend it's not
renderable until that is fixed.
Fixes CI from failing.
I naively assumed the EXT_color_buffer_float and
EXT_color_buffer_half_float extensions would mirror each other, but they
do not. The float extension explicitly excludes RGB32F from the
renderable formats.
