e18c5534 gpu: Consider scissor when intersecting with recangle

Merge branch 'wip/otte/for-main' into 'main'

People were experiencing some issues when running GTK 4.16 apps
under kwin, which now enables the experimental Wayland protocol
by default. While the testing is valuable, we don't want to
make users of the stable GTK guinea pigs, so switch color
management from opt-out to opt-in. Use

GDK_DEBUG=color-mgmt

to enable use of the xx-color-manager-v4 protocol.

On Windows, we build a lot a subprojects. And some of them require
meson 1.3.0 now, so use that.

Make color management opt-in

We had code trying to handle the case of focus coming from a
child, but it is running too late to be effective. Instead,
keep a flag that tells us if the Emoji picker is still open.

And use the format from `gdkcolordefs.h` for good measure.

Lots of newer apps that use their appid as their icon name don't set
window icons, since they aren't used in GNOME. Instead of setting it
manually in every app, just default to it.

Only set the icon if it exists in the icon theme.

Remove manually set default icons in the demo.

No tests as GtkApplication doesn't have any in the first place.

The expander window is not a dialog anymore, so attempting connecting to
its "response" is invalid and throws a critical:
  signal 'response' is invalid for instance '<PTR>' of type 'GtkWindow'

Right now, child is NULL when starting a drag in the main area and
moving the pointer onto the colors, there releasing it.
To avoid gtk_widget_get_ancestor thowing a critical, early exit if child
is NULL.

To limit the amount of files installed by meson install, users can
specify specific classes of files they actually want to install.

Most to be installed files are automatically tagged by meson correctly
based on what function produced them, but it can't for some (esp. those
installed using install_data/subdir).

As gschema files *should typically* be available at runtime, give them
the "runtime" tag.

See https://mesonbuild.com/Installing.html#installation-tags

Pixiewood expects well-formed XML files, whose tags match the AppStream
namespace. Note that AppStream itself does not do this, so picking a
prefix for the namespace is fine for pixiewood but not AppStream.

There were several places where unnecessarily big minimum sizes
were hardcoded. Instead, set a reasonable default size for the
dialog and the let window shrink further.

Helps for mobile situations.

This is in line with what most tools do when printing --help
(and GOptionContext alike)

We can reach here in early exit paths when the shortcut_files have not
been initialized yet.

I want to include this header from DirectX C++ code.

We return an empty format list when dmabufs aren't supported, not NULL.

And the sink was treating the empty format list by setting no fourccs
on the caps, which GStreamer conveniently interpreted as "any",
not as "none".

Instead of looking at availability of a GL context, check the
memory's type.

That's what we do everywhere else and GL is not special.

That was a copy/paste error in 2ad2bae1.

Thanks to Anders Jonsson for spotting it.

Doing otherwise risks that the focus is moved back to the entry,
causing everything to be selected, and then replaced by the Emoji
we insert. Which is not the desired effect!

Code to grab focus when closing the chooser was added to fix #3112,
but it seems the issue has been fixed elsewhere since. Since this
code is now redundant, remove it.

Also reverts 1d1ef311, since it,
as far as I can tell, tried to fix a selection issue caused by the
explicit focus grab when closing the chooser. It no longer made
any difference in my testing.

Since we're no longer requesting a fixed height for the emoji
chooser, we need to add top/bottom margins to the placeholder to
prevent it from touching the edges.

The atspi.Value:Text property is a string; if the valuetext property is
unset, we should return an empty string.

The 3 * underline thickness that Pango gives us for the height
of error underlines is just too big for the dotted line we use
now. Shrink it down.

`g_variant_get ("as")` gives a heap-allocated `GVariantIter` pointer,
not a `GStrv`, so the free function being used here was wrong. However,
the `event_types` variable wasn’t actually read at all, so it’s better
to just drop it completely.

This fixes heap corruption seen in valgrind when using GTK with
assistive technologies (such as a screen reader) turned on.

On half the code paths in this function, the `sender`/`event_name` won’t
be passed anywhere which requires ownership, so there’s no need to make
a copy of them by default. Only copy them when needed.

This fixes a leak of the `sender` on the control flow paths where it’s
not inserted into the hash table.
