We were missing surfaces in a few places.

Cairo borders fixage

See merge request !765

This fixed the reftest introduced in the previous commit.

I'm using a mesh gradient here instead of drawing 4 individual sides to
avoid artifacts when those sides overlap in rounded corners.

c18d2872 introduced a misrendering in
the Cairo fallback rendering code while fixing another one.

This test exposes that problem.

We must still reset cursors.

Cursor things

We have convenience api for this.

Style prop change

Thats the point. And we were missing the proper
flags to make GTK do the right thing when
changing font-kerning in the inspector.

Minor corrections to the AFFECTS flags docs.

css: Letterspacing affects text size

gdk/wayland: Listen to wl_surface events on tablet cursors

Closes #1675

See merge request !761

It does. And we were missing the proper
flags to make GTK do the right thing when
changing letter-spacing in the inspector.

And update the surface accordingly (eg. scale on hidpi). The mechanism
that did that for wl_pointer has been made generic so it can be shared
with tablets too.

gdkdevice-wayland: Update pointer scale on tablet tool proximity events

See merge request !582

wayland: Avoid using uninitialized memory

Closes #1328

See merge request !757

_gdk_wayland_cursor_get_buffer was not initializing
its out variables in the 'not found' case. This
was showing up in protocol traces as garbage hotspots
being sent to the compositor.

Closes: #1328

The test just loads all of GTK's themes and makes sure they cause no
errors or warnings from the CSS parser.

Seems to have been forgotten a few times.

gtk_css_provider_get_named() is the old GTK3 style API to load themes.

Instead, export the function we currently use,
gtk_css_provider_load_named().

As a side effect we allow people to load a theme as often as they want
without conflicting with GTK's theme.

We can't guarantee that we can load svgs, so
we shouldn't spew criticals when some of our
own resources fail to load due to that reason.

gtk_css_image_recolor_load_texture may leave
recolor->text as NULL without setting error.
No need to crash for that.

The new css parser complains about an unknown pseudo-class
here.

The touch popup was meant to have linked buttons.

Otherwise, we get a spinning missing-image without
librsvg.

CI: Build with --werror

This turns on --werror in the Fedora CI builds.

Add more gcc error flags

gtk-demo: Add a gear menu

See merge request !753

The centered labels just look disorderly.

When we moved content_area to a sibling of action area,
it changed orientation from vertical to horizontal.
Adapt to this change.

Modernize the about dialog, and make it available
from a gear menu, together with a way to bring up
the inspector.
