Take the has_mipmap boolean in our internal constructor.
The code is still in a bit of flux - we still try to
determine if we have a mipmap while poking at formats.
Eventually, that code should probably be moved to the
builder side.
Building GL textures is complicated, so create an object to make them.
So far, this object just contains the functionality of
gdk_gl_texture_new(), but that will change in the future.
BuilderListItemFactory isn't quite suited for our purposes, primarily
because you can't pass user data to BuilderListItemFactory. Because
we can't get the data we are using a workaround to get the
GtkFileChooserWidget ancestory, which used to work, but with the
recent list view changes no longer doesn't. Use GtkSignalListItemFactory
with the GtkFileChooserWidget as the user data.
It's not enough to sanitize values when starting an animation, as the
adjustment can reconfigure itself while the animation runs.
So as a simple way to handle this, we sanitize every value right before
setting it, too.
In the future we might also want to look at sanitizing start/end values
of the animation.

There are a lot of cases where properties are implemented in classes but
the getters for these exist in an interface that class implements.
A common Example is g_list_model_get_n_items() being the getter for
GtkWhateverListModel::n-items.
But also property implementations that don't use override_property()
(usually because they have a different default) are handled by this.
When adding mask nodes, I overlooked that
we have two separate functions for determining
what transforms a node supports without offlines.
Since we claim that mask nodes support general
transform, they must certainly support 2d transforms
as well.

Part of #5725
The test doesn't hold 2 references, it holds only one.
The reason one unref can cause a leak is that some backends - like X11 -
only destroy the surface once the DestroyNotify event from the X server
has come in.
X11 does add an extra reference to surfaces that gets released when the
DestroyNotify event arrives.
Wayland doesn't ave such an event, so that reference never gets
released.
This fixes a copy/paste error introduced in commit 590f3dfa1f.
We want to remove the event queue from the list of event queues, not the
surface.
Otherwise the freed queue stays in the list and the next time an event
comes in, we access invalid memory.
Fixes thinko introduced in commit 7fafa5133b.
Luckily, we leak all surfaces, so this problem never occured.
We want to support GLES 2, so make sure we test that support.
Also force-disable common extensions we don't explicitly check for and
don't want to accidentally use.
They're not needed and GLES doesn't technically support them, even
though GTK had been using them via epoxy sneakily using the
GL_OES_vertex_array_object extension behind our back.
Cache the last looked up item and use it for looking up the next item if
it's closest. This massively speeds up iteration over the model, because
each call to get_item() will be adjacent to the previous one.
Improves performance of the inspector quite a bit.
When the variant-editor emits a callback, it might not actually have
edited the value in question. Try to detect that by only emitting
signals if the value changed.
gsk_vulkan_render_download_target() currently resets the uploader
objects before downloading the image that it produces. This is
problematic because there might be unreleased buffers and images
in the command queue.
In particular, this can make validation layers complain about the
glyph atlas - of all things! - upload buffer being released while
still being used by the command queue.
Fix that by resetting the uploader after downloading the image.
Check if the driver supports MAILBOX and prefer using it; in its
absense, checkif the driver supports IMMEDIATE and prefer using

the interface isn't supported at all, since the proxy

Fixes: #5733
We want to keep the wl_surface around, because surfaces create their
resources on construct and keep them until destroyed. See the HWND ond
Windows and the XWindow on X11.
This is relevant for graphics resources, where we want to have access
to the VkSurface and eglSurface while the GdkSurface is hidden.
We also want these surfaces to be permanent and not change during the
lifetime of the GdkSurface.
What we can - and must - destroy however are the xdg surfaces, because
those handle visibility on screen.
And we also need to ensure no buffer is attached, so that during the
next creation of the xdg surface we don't get a protocol error.
gdk_wayland_surface_maybe_resize() just calls
gdk_wayland_surface_update_size(), so make all callers call that one
instead.
The check that it does is done by the other function again.
This workaround - were it ever to trigger - is broken today. It destroys
the wl_surface and all associated structs but does not recreate the
xdg_popup or xdg_toplevel struct, so it would cause a hidden window.
The workaround looked a lot different when it was introduced in commit
83b54bab57, too - both in what it did and
in what the vfuncs did that it called.
.view does absolutely nothing in Default style since the whole box is
covered with a GtkNotebook which has its own background, and adds an
unwanted background onto the tab strip in Adwaita.
Some bindings (GJS!) could add temporary references to the GAsyncResult
argument that we return, and thus to the GTask, which may cause the
dialog not to close when the finish function is called (but at garbage
collection instead!).
To prevent this, just manually destroy the window (by removing the task
data), so that we are not bound to the GTask lifetime anymore.

If we click close enough between lines, and with the maximum distances applied
by GtkGestureClick we could jump between lines when handling double/triple
click for word/line selection.
Ensure that the whole operation stays in the same line and reset the
gesture/counter if we do move between lines, so we start from scratch in the
new line.
The date/time column relies on the filechooserwidget to format the date
properly. During bind, the filechoosercell, get the filechooserwidget
ancestor, but now due to changes in the listview, the cell isn't a
child of the filechooserwidget at that point. Since this is deeply
ingrained into the filechooserwidget, let's keep the same behavior,
but move it to filechoosercell in realize. Alternatively, we could have
used a signal factory (with the file chooser widget as the user data),
but that would have been a major overhaul.
The format of the type column depends on the the type_format, which
is stored in the filechooserwidget. We get that setting by looking
for the filechooserwidget ancestor, which no longer works after recent
changes to the list views (it was fragile to begin with). At one point,
the setting appears to have been dynamic, but now it is only loading
from GSettings, so let's simply do the same within FileChooserCell.
32247bc50e made several changes to account for the
fact that we no longer have a NULL editable at the beginning of the list
model. The commit mistakenly left out one change in remove_file(),
which causes the wrong file to be removed.
Now that the paint demo lets us test this, it has
become apparent that this condition is wrong, and
we don't get the expected events if stylus-only is
FALSE.
The current implementation of the glyph cache deals with atlases by
padding them with 1 pixel at the beginning, at the end, and between
each glyph.
That's cool and all, however, there's a very subtle problem with
this approach: the contents of the atlas are garbage, so this padding
is filled with garbage memory!
Rework the Vulkan glyph cache to draw each and every glyph in a
surface that has 1 pixel border of padding around it. Ensure the
surface is completely black by drawing a rectangle before handing
it to Pango to draw the glyph. Update tx and ty to pick the texture
position adjusted to the 1 pixel padding. The atlas now starts at
position (0, 0), since each glyph individually contains its own padding.
To improve legibility, add a PADDING define and use it everywhere.
Vulkan renders text using VK_BLEND_FACTOR_ONE_MINUS_SRC_ALPHA and
VK_BLEND_FACTOR_SRC_ALPHA, but that implies per-channel alpha
blending, which currently produces the wrong results when blending
glyphs with the images beneath them.
Use the default pipeline constructors, which implies using the
ONE and ONE_MINUS_SRC_ALPHA.
When determining double-clicks, don't use the distance
threshold for touch events. It is very hard to double
touch reliably within a few pixels of the same position.
Fixes: #5580
Typically, a popover gets mapped when shown and unmapped when
hidden. A situation there that breaks is where the popover gets
recursively unmapped/unrealized when its root is destroyed.
In that situation, the popover does however unmap (without being
hidden first), moving the GTK grab from show/hide to map/unmap
will handle the previous situations, plus this one.
Fixes things being unclickable if e.g. a modal dialog got a
popover popped up, then got closed via Alt-F4.

Calling gtk_list_box_remove_all() is a no-op with a bound model; after
the introduction of the remove_all() method in 49e56fc7, we were left
with row widgets after the dispose() call chained up.
We could restore the explicit unparenting inside dispose() instead of
calling remove_all(), but since the bound list model is provided by the
user of GtkListBox, it's more appropriate to unbind it in the dispose()
implementation, to avoid any potential reference cycle (especially in
higher level languages that have no explicit reference acquisition).
We clean up the bound model, and its associated state, if any; and then
we remove all the row widgets that are left.
Basically what GL does, but without any debug or feature flag
to gatekeep it, since the Vulkan backend itself is experimental
already.
Ceil surface sizes, and floor coordinates, to the fractional scale
value.
The rects passed to the clip region are in buffer coordinates, and
must not be scaled. Consider the following scenario: Wayland, with
a 1024x768@2 window. That gives us a 2048x1536 raw image. To setup
the Vulkan render pass code, we'd scale 2048x1536 *again*, to an
unreasonable 4196x3072, which is (1) incorrect and (2) really
incorrect and (3) can lead to crashes at best, full GPU resets
at worst - and a GPU reset is incredibly not fun!
Now that we pass the right clip regions at the right coordinates
at all times, remove the extra scaling from the render pass.
This part of the Vulkan renderer is almost exactly equal to the GL
renderer, and the GL renderer already does that since at least
2a38cecd33. Copy that into the Vulkan renderer.
A nice side effect from this commit is that resizing a window now
actually works again.
Sneak in a trivial cleanup by using a variable to hold the draw
index.
This was a tricky one to figure out, but it's pretty simple to
understand (I hope!).
So, this AMD card I'm using requires buffer memory sizes to be
aligned to 16 bytes. Intel is aligned to 4 bytes I think, but
AMD - or at least this AMD model in particular - uses 16 bytes
for alignment.
When creating a a particular texture (I did not determin which one
specifically!) a buffer of size 1276 bytes is requested.
1276 / 16 = 79.75, which is clearly not aligned to the required
16 bytes.
We request Vulkan to create a buffer of 1276 bytes for us, it
figures out that it's not aligned, and creates a buffer of 1280
bytes, which is aligned. The extra 4 bytes are wasted, but that's
okay. We immediately query this buffer for this exact information,
using vkGetBufferMemoryRequirements(), and proceed to create actual
memory to back this buffer up.
The buffer tells us we must use 1280 bytes, so we pass 1280 bytes
and everyone is happy, right? Of course not. We pass 1276 bytes,
and Vulkan is subtly unhappy at us.
Fix that by passing the value that Vulkan asks us to use, i.e.,
the size returned by vkGetBufferMemoryRequirements().
This is what GL does, and for a reason: it can lead to width or
height for very small glyphs. Also, switch to dividing by a float
(1024.0) instead of an integer (1024).
This doesn't make any difference now, but will allow us to copy
subregions more easily. This is not obvious, but here's a quick
explanation:
Leaving 'bufferRowLength' and 'bufferImageHeight' implies that
Vulkan will assume the size passed in the 'imageExtent' field.
Right now, this assumption is correct - the only user of this
function is the glyph cache, and it only copies and uploads
exact rects. Next commits will change that assumption, so we
must pass 'buffer*' fields, and tell Vulkan, "this part of the
buffer represents an image of width x height, and I want the
subregion (x, y, smallerWidth, smallerHeight) of this image".
When creating an image using gsk_vulkan_image_new_for_framebuffer(),
it passes VK_IMAGE_LAYOUT_COLOR_ATTACHMENT_OPTIMAL.
However, this is a mistake. The spec demands that the initial
layout must be either VK_IMAGE_LAYOUT_UNDEFINED or
VK_IMAGE_LAYOUT_PREINITIALIZED.
Apparently this was an oversight from commit b97fb75146, since the
commit message even documents that, and all other calls pass either
VK_IMAGE_LAYOUT_UNDEFINED or VK_IMAGE_LAYOUT_PREINITIALIZED.
Create framebuffer images using VK_IMAGE_LAYOUT_UNDEFINED, which is
what was originally expected.
Removing all items from containers is a common use case.
Without this applications needed to implement this manually.
It makes senses to handle it here.
Fractional scaling with the GL renderer is
experimental for now, so we disable it unless
GDK_DEBUG=gl-fractional is set.
This will give us time to work out the kinks.
This commit combines changes in the Wayland backend,
the GL context frontend, and the GL renderer to switch
them all to use the fractional scale.
In the Wayland backend, we now use the fractional scale
to size the EGL window.
In the GL frontend code, we use the fractional scale to
scale the damage region and surface in begin/end_frame.
And in the GL renderer, we replace gdk_surface_get_scale_factor()
with gdk_surface_get_scale().
Whenn setting gtk_builder_set_allow_template_parents(), the builder
instance will accept
<template class="GtkWidget">
for a GtkBox instance.
It's going to be used with the new GtkColumnViewCell objects, so that
it's backwards compatible with ui file factories that use GtkListItem.
That way, local scrolling is available and the scrolling isn't random.
Recycling should now involve reordering the recycled widgets instead of
just keeping their order because all of them got recycled.
This allows setting a factory to toggle per-row properties.
Implemented are selectable, focusable and activatable.
These are meant to supercede the per-cell selectable and activatable
properties, which make no sense individually.
The focus property makes it possible to focus rows instead of cells,
which is the default behavior.
There is no way to set it yet, this is just to prove that it works.
It also changes the focus behavior of rows. They are now always
focusable - unless turned off by the factory once that is possible.
This makes the question if a listitem can be focused or not an explicit
decision by application developers.
Previously an item could be focused if it was selectable and no child or
grandchild was focusable - so if you put a label and icon into it, the
item was focusable, but if you put a GtkTreeExpander or a GtkButton into
it, the item wasn't. This needs to be decided explicitly now.
Technically this is an API break, because the previous behavior does not
exist anymore.
But I really don't want to make this a tristate (focusable, not
focusable, automatic), because then binding it to other things gets
hard, and because all the other focusable proeprties are booleans, too,
and working with them gets a lot harder.

Cairo can do that, so just enable it:
* Create surfaces with the correct fractionally scaled size.
* Set the Cairo surface's device scale to that number.
Instead of setting the buffer scale via the buffer-scale command, set it
via the viewport.
This technically allows setting fractional scales, but we're not doing
that.
Instead of tracking a single scale, track x and y scales separately.
Factor out gsk_vulkan_render_pass_new() into a private function that
receives both scales, and pass 'scale_factor' for both.
April fools!
No, really.
The fractional scale protocol is just a way to track the surface scale,
but not a way to draw fractional content.
This commit uses it for that, so tht we don't rely on tracking outputs.
This also allows magnifiers etc to send us a larger (integer) scale if
they would like that, that is not represented by the outputs.
This is mostly a cosmetic change, and the goal is twofold:
1. Make it easier to spot unimplemented render node types; and
2. Prepare for a small rework
The implementation for each node now lives in specific functions,
like the GL renderer; unlike the GL renderer, however, we use a
node type vtable to map GskRenderNodeType → implementation. Render
node without an implementation map to NULL, and use the fallback
implementation. Render nodes that fail any check and return FALSE
also use fallback implementation.
The scrolling code assumes the adjustment values are up to date or
it crashes and before we've run size_allocate() we haven't update them.
Fixes a crash in the gtk-demo scrollinfo that would set the adjustments
with random values (via ScrolledWindow.set_child()) and then scroll in a
tick callback right before the (first) size_allocate().
The Lunarg validation layers seem to have been deprecated in favour
of the Khronos ones. There's no reason not to have both, to accept
loading both - simultaneously, even.
Instead of passing a single, potentially massive rectangle that is
just the extents of the damage rect, collect and pass all damage
rects individually.
Add a new flag to track whether buffer scale is dirty or not,
and centralize calling wl_surface_set_buffer_scale() in a single
place: gdk_wayland_surface_sync_buffer_scale().
gdk_wayland_surface_sync_buffer_scale() is only called by
gdk_wayland_surface_sync(), which itself is called by the GL,
Vulkan, and Cairo contexts, right before submitting a frame.
This ensure that each frame has an up-to-date buffer scale.
This mimics how opaque and input regions are tracked.
According to the at-spi2 docs, for a widget to be considered visible,
it needs both the showing and visible states. Many applications rely on that,
for example the flat review functionality of Orca.

Don't fudge around poking through the listview, trying to get a model
and selecting it directly. Instead, use the proper way and activate the
"listitem.select" action.
Instead of directly calling select_item(), trigger the select-item
action of the focused child.
We do this convoluted calling into the widget because that way
GtkListItem::selectable gets respected, which is what one would expect.
Plus, this code is usually triggered via keybindings, and this way the
ListBase keybindings work identical to the ListItem keybindings.
If we encounter a node or texture the 1st time and they are going
to be used again, give them a name.
Then, when encountering them again, print them by name instead
of duplicating them.
We extend the syntax for nodes from:
<node-type> { ... }
to
<node-type> { ... }
<node-type> <string> { ... }
<string>;
where the first is the same as before, the 2nd defines a named node and
the last references a previously defined node.
Or to give an example:
color "node" {
bounds: 0 0 10 10;
color: red;
}
transform {
bounds: 20 0 10 10;
child: "node";
}
This will draw the red box twice, once at (0,0) and once at
(20,0).
The intended use for this is both shortening generated node files as
well as allowing to write tests that reuse nodes, in particular when
dealing with caches.
We extend the syntax for textures from just:
<url>
to
[<string>] <url>
<string>
where the first defines a named texture while the second references a
texture.
Or to give an example:
texture {
bounds: 0 0 10 10;
texture: "foo" url("foo.png");
}
texture {
bounds: 20 0 10 10;
texture: "foo";
}
This will draw the texture "foo.png" twice, once at (0,0) and once at
(20,0).
The intended use for this is both shortening generated node files as
well as allowing to write tests that reuse textures, in particular when
mixing them in texture and texture-scale nodes.
If we map, reposition, unmap, remap, the reposition feedback from the
last time a popup was mapped might be received while we're dealing with
the new version of the popup. At this point, the old reposition token
has no meating, so lets drop it. Also reset the reposition tokens when
creating new protocol objects, so that the reposition token are as if
we're in the initial state.
This fixes an issue where we'd get stuck if repeatedly smashing a button
that'd create popups that'd immediately get dismissed by the compositor.
Since Wayland 1.15, it is now possible to use absolute paths in
"WAYLAND_DISPLAY".
In that scenario, having a valid "XDG_RUNTIME_DIR" is not a requirement
anymore.
For this reason we remove the "XDG_RUNTIME_DIR" check and we let
`wl_display_connect()` decide if our environment is correct.

An inert gridview is a gridview that does not use the factory. This
allows faster updates because no calls into user code need to happen.
A gridview is inert when either:
- It is not rooted.
- It is not visible.
- No factory is set (that one is obvious)
The gridview does not need to be inert without a model, as that case is
handled by the item manager.
This should allow Nautilus to keep both the gridview and the columnview
around, and just gtk_widget_hide() the unused widget.
The code for now does not disable the item manager, as some
functionality of the item manager is required to allow setting scroll
positions and such.
But that is a place where more gains could be found if profiling showed
that was useful to do.

The widget would teardown the factory on unroot to avoid unnecessary

However, recycling may reposition widgets, and repositioning widgets
does a unroot/root.
We don't want to recycle widgets then.
The implementation lives (as always) in GtkListBase.
This is a feature request from the Nautilus developers, who currently do
some hacks to emulate that behavior and it apparently only breaks
sometimes.
We connect gtk_scrolled_window_update_use_indicators

Just like GdkToplevel::compute-size, the size argument of the signal is
given to the handlers by GDK; it's not an out argument meant to be
allocated by the caller.
The size argument is passed to the signal by the GDK surface machinery,
as is: it's not going to be allocated by the caller (since it's a
signal), and it's not an out argument.
The cursor-theme-size setting is documented as
'0 means the default size'. Make it so by using
size 24 if we see a 0. Its better than crashing.

The function is going away, and the computation
here was wrong anyway. Instead, add a helper that
properly computes the pointing-to rect in surface
coordinates and use it everywhere.
The widget paintable uses the widgets bounds
as intrinsic size, so we need to offset from
that to the allocation, which is what the
coordinates are relative to.
Text handles had the same problem as popovers.
They were interpreting their pointing-to rectangle
relative to the widgets bounds, when it is meant
to be relative to the widgtets allocation.
While we touch this code, rewrite it to use
gtk_widget_compute_point.
When we don't have a pointing-to rectangle, we want to place
the popover wrt to the parents bounds. But if we have a
pointing-to rectangle, it is relative to the widgets allocation,
which is different from the bounds.
We were not handling the second case correctly, leading to context
menus in the text view being mispositioned by the widgets CSS padding.
While we are touching this code, rewrite it to handle transforms.
Fixes: #5695
Since we are making GdkGLContext call the core wgl*() functions directly
instead of via libepoxy, drop the workarounds that we needed for notifying
libepoxy that wglMakeCurrent() outside of GDK/GTK was called.
This way, we clean up the code, and as a result, we can use the GstGL
APIs like the other platforms to query what GL api that is to be used.
For ensuring that things work between different threads, we now call
gdk_gl_context_clear_current() in place of calling wglMakeCurrent(xxx,
NULL), so that we make sure that there is no current GL context on a
thread outside of GstGL's thread, which Windows does not like.
We might be dealing with GL contexts from different threads, which have more
gotchas when we are using libepoxy, so in case the function pointers for
these are invalidated by wglMakeCurrent() calls outside of GTK/GDK, such as
in GstGL, we want to use these functions that are directly linked to
opengl32.dll provided by the system/ICD, by linking to opengl32.lib.
This will ensure that we will indeed call the "correct" wgl* functions that
we need.
This should help fix issue #5685.
When the GL texture already has a mipmap, we don't
have to download and reupload it to generate one.
We differentiate the handling for texture scale nodes,
where we do want to force the mipmap creation even if
it requires us to reupload the GL texture, and plain
texture nodes, where we just take advantage of a
preexisting mipmap to allow trilinear filtering for
downscaling, or create one if we have to upload the
texture anyway.
Make GdkGLTexture determine if the texture has
a mipmap, and provide private API to query this
information.
This check is done in gdkgltexture.c instead of
gskgldriver.c, since we're already binding the
texture here for other reasons, so it is easy
to query a few more things.
- grab_focus() on a row (happens with scroll_to()) keeps the focus
column intact if possible.
- <Tab> and <Shift-Tab> move through the cells in order, and move
to the next row when at the end.
- <Up> an <Down> move to the next/prev row, keeping the same column
focused.
- <Left> and <Right> move to the prev/next cell, if one is available.
If not, they stay where they are.
Make it move focus just like GtkWindow would.
Otherwise the listview will (try to) handle it and move focus between
cells - which doesn't do anything for lists and only works with grids.
This is a split of GtkListItemWidget into the generic parts of factory
using widgets.
On top of it there's GtkListItemWidget, which takes care of GtkListItem.
They're not used outside of GtkListBase, so no use to have them in the
header.
Requires moving one function up in the source now that the forward
declaration is missing.
create_at_context was confused - it stored a reference
to the newly created context in priv->context, but then
also returned a reference, and the caller stored that

Store texture coordinates for each slice

This one exhaustively tests reusing the same model as a child model for
many nodes.
This tracks that multiple items-changed signals emitted at the same time
(or multiple handlers for one such signal) doesn't put the treelistmodel
in an inconsistent state while it is handling all of them.
I'm not sure this (ab)use of treelistmodel should be officially
supported, but it works today, so let's test it to see if we can keep it
working.
If there is no other widget in the group that we can focus, don't focus
and activate ourselves.
Otherwise the arrow keys on checkbuttons toggle the checkbutton.
If a GtkImage is using an icon we use a gtk-icon-filter to se the icon
opacity when in insensitive state, however when using other kinds of
pictures we do not apply the same style leading to an inconsistent
result.
Closes: #5683
Items should be cleared when the node is discarded, not when the node's
children are discarded - which can also happen when a node is collapsed.

In constrast to our other tests, these use
textures that are big enough to force slicing
with setting GSK_MAX_TEXTURE_SIZE, which we
will use in the following commits to improve
test coverage.
It is useless to have node files with references
to external files in the testsuite, so turn such
textures into data urls by doing a serialization
roundtrip.
No user knows that we have an internal function called
gtk_tree_list_row_destroy() that gets called when a row gets removed
from the treelistmodel.
So everyone was probably just making stuff up about what "destroy"
means.
Related: #5646
That way, we can return the item even after the row is removed. This is
particularly relevant in ListItemFactory::unbind callbacks because they
often use gtk_tree_list_row_get_item() and user code never tracks
changes to this property.
A side effect of this is that the item will survive until the row gets
destroyed, but that's what users expect anyway, so we can live with it.

This is a good idea to avoid reentrancy problems when any child model
(or potentially more than one child model) has started emitting
items-changed but the emission hasn't arrived in this model yet.
At tat point, we'd get_item() the wrong item from those models.
We want to avoid such cases of reentrancy.

We cheat and just set the texture parameters instead and hope nothing
explodes.
So far it didn't.
This is only needed to support GLES 2.0 so it's quite a limited set of
hardware these days.
Instead of uploading a texture once per filter, ensure textures are
uploaded as little as possible and use samplers instead to switch
different filters.
Sometimes we have to reupload a texture unfortunately, when it is an
external one and we want to create mipmaps.
When filtering changes for an already-cached
texture, we need to clear the render data
before setting the new one, otherwise it
does not take and we end up reuploading
the texture every frame.
Code above ensures that i is always in [0, n_columns - 1] range, so
the condition was always true, which resulted in filler tile always
being added to the grid. As the result, an empty row appeared at the
end of the grid if the number of columns divided the number of items.
Only add filler tile if last row is not full, i.e. when i > 0.
a11y: Fix the logic in gtk_accessible_get_next_accessible_sibling which decided whether we will use the overridden sibling on the context.
See merge request GNOME/gtk!5659
We were culling children based on the content box, but clipping via
overflow happens on the padding box, so we need to use that one instead.
Fixes issues with items not being visible / disappearing in Nautilus
when they are near the border.
Resolves#5380
The GtkUriLauncher calls into the openuri portal, which distinguishes
between files, directories, and URI. The GtkFileLauncher contains logic
to deal with this, because it can already handle the file and folder
differences.
If we have a file:// URI it's easier to create a GFile out of it, and
use the GtkFileLauncher API, while leaving the GtkUriLauncher API for
every other URI scheme.
Same fix as de3c1d0c73, for GtkLabel.

Otherwise GL surfaces that redraw without changing the hotspot have it
applied on top every frame and quickly slide away.
The cairo path and the X11 backend do not have this bug.
The GL Wayland drag surface code path has a bug where it does not reset
the hotspot, so if a GL-backed draw surface redraws without resizing or
resetting the hotspot, it moves away. The next commit will fix that, but
this commit adds a test for that.
Allow to set max texture size using the
GSK_MAX_TEXTURE_SIZE environment variable.
We only allow to lower the max (for obvious
reasons), and we don't allow values smaller
than 512 (since our atlases use that size).
GdkDragSurface-backed widgets are not parented to an existing widget,
unlike popovers, and like toplevels. This means that there's nobody to
actively call gdk_drag_surface_present() to update the size, and
GdkDragSurface should do it on its own, just like GdkToplevel.
This commit implements this for the Wayland backend.
Compute our size when requested by the backend. This makes GtkDragIcons
actually recompute their size when it changes, instead of getting stuck
with the first size and potentially underallocating.
Similarly to GdkToplevel, GdkDragSurface's compute-size should be called
by backends to query the current surface size, and should be connected
to by widget implementations (like GtkDragIcon) to report the current
size.

When fatal warnings were turned on, the developer would never see which
widgets were left as children to the widget that triggered the warning as
those were printed in separate g_warning calls.
Print a single warning with all the info so runs with fatal warnings
aren't left without any info.
This state is used for visited link-like widgets.
It has no ARIA equivalent, e. g. can not be set programmatically, but it
exists in the browser environment as well.
Showing a destroyed window might cause an application to
behave in an unexpected manner. For example, showing a
dialog after it has been closed by the user might cause the
application to freeze. The warning will help developers to
track down the issue.

GSK render nodes can be serialized and deserialized using APIs such as `gsk_render_node_serialize()` and `gsk_render_node_deserialize()`. The intended use for this is development - primarily the development of GTK - by allowing things such as creating testsuites and benchmarks, exchanging nodes in bug reports. GTK includes the `gtk4-node-editor` application for creating such test files.
The format is a text format that follows the [CSS syntax rules](https://drafts.csswg.org/css-syntax-3/). In particular, this means that every array of bytes will produce a render node when parsed, as there is a defined error recovery method. For more details on error handling, please refer to the documentation of the aprsing APIs.

For more details on error handling, please refer to the documentation of the parsing APIs.
The grammar of a node text representation using [the CSS value definition syntax](https://drafts.csswg.org/css-values-3/#value-defs) looks like this:
Each node has its own `<node-name>` and supports a custom set of properties, each with their own `<property-name>` and syntax. The following paragraphs document each of the nodes and their properties.
Each node has its own `<node-type>` and supports a custom set of properties, each with their own `<property-name>` and syntax. The following paragraphs document each of the nodes and their properties.
When serializing and the value of a property equals the default value, this value will not be serialized. Serialization aims to produce an output as small as possible.
To embed newlines in strings, use \A. To break a long string into multiple lines, escape the newline with a \.
# Names
### Nodes
Nodes can be given a name by adding a string after the `<node-type>` in their definition. That same node can then be used further down in the document by specifying just the name identifying the node.
### Textures
Just like nodes, textures can be referenced by name. When defining a named texture, the name has to be placed in front of the URL.
