imwayland: Do not defer commit() after set_surrounding_text()
For reasons that only apply to the old serial handling, asking for
the surrounding after IM changes resulted in lazy handling of
commit() afterwards.
With the recent interpretation of serials, this problem became more
apparent, since it is in fact very likely that the last interaction
step after an IM change is notifying of the changed surrounding
text after the IM change was applied.
Make handling of surrounding text similar to caret position changes,
always commit() after the state change, but skip through non-changes.
This makes the compositor state fully up-to-date after an IM change.

imwayland: Connect OSK activating gesture to parent widget on editables
The gesture as connected currently on the child GtkText is easily overridden
by the parent editables (and gently done so in the attempt to consume all
clicks).
Connect this gesture to the parent editable widget in these cases, so the
gesture can cohabit with the click-consuming one. It's not part of the same
group, but it won't be abruptly cancelled.
gdk: always populate GDK_AXIS_{X,Y} in merged event history
Since GdkTimeCoord stores only axis values, prior to this change,
if a device didn't report GDK_AXIS_X or GDK_AXIS_Y, the history
attached to merged motion events wouldn't contain any positional
information.
Commit 6012276093ea10dc0913c38d9123c37b08a20264 already addressed
this issue for devices without tools by storing the event position
in GdkTimeCoord using GDK_AXIS_X and GDK_AXIS_Y and augmenting the
GdkTimeCoord's axis bitmask accordingly.
This change generalizes that workaround to all devices. Note that
if a device DOES report values for GDK_AXIS_X and GDK_AXIS_Y, those
values won't be overwritten.

gsk/gl: Always align offscreen rendering with the pixel grid
This fixes two issues with the offscreen rendering code for nodes with
bounds not aligned with the pixel grid:
1.) When drawing to an offscreen buffer the size of the offscreen buffer
was rounded up, but then later when used as texture the vertices
correspond to the original bounds with the unrounded size. This could
then result in the offscreen texture being drawn onscreen at a slightly
smaller size, which then lead to it being visually shifted and blurry.
This is fixed by adjusting the u/v coordinates to ignore the padding
region in the offscreen texture that got added by the size increase from
rounding.
2.) The viewport used when rendering to the offscreen buffer was not
aligned with the pixel grid for nodes at coordinates not aligned with
the pixel grid. Then because the content of the offscreen buffer is not
aligned with the pixel grid and later when used as textures sampling
from it will result in interpolated values for an onscreen pixel. This
could also result in shifting and blurriness, especially for nested
offscreen rendering at different offsets.
This is fixed by adding similar padding at the beginning of the
texture and also adjusting the u/v coordinates to ignore this region.
macos: Skip running `showAndMakeKey` when a window is minimized by user action
When a window is minimized by user action, the `showAndMakeKey` method is not executed when idle. This prevents the window from being un-minimized immediately.
And allow programmatic minimization of a window by un-minimizing them in `_gdk_macos_toplevel_surface_present`
x11: Check return of gdk_x11_get_xatom_name_for_display
When given an invalid atom, gdk_x11_get_xatom_name_for_display can

Check for NULL.
Why I'm seeing a bad atom there is probably a separate question.

gtkimmulticontext: Handle switches between displays
Currently the GtkIMMultiContext may stick to a delegate GtkIMContext
that no longer applies after the multicontext is dissociated from
any widget.
Handle set_client_widget() so that it can handle changes between
widgets from 2 different display, but also so the delegate is made
NULL whenever the context has a NULL widget.
Doing so, any new client widget results in a new delegate IM context
lookup from the right GdkDisplay and GtkSettings, which avoids any
mix up.

Otherwise a stray scroll controller may prevent others from getting hold

WebKit's GTK 4 port can give us textures with an internal format of
GL_RGBA with GL_UNSIGNED_NORMALIZED and a bit-depth of 8. This fixes
warnings for every GdkGLTexture created/delivered to the GskGLRenderer.
The format is essentially the same as GL_RGBA8 since it is normalized
between 0.0..1.0 for 8-bit components.

surface: Use correct display when destroying a surface for depth switch
When surface depth switches from non-high-depth to high-depth (or vice
versa) the current surface has to be destroyed before a new one can be
created for this window. eglDestroySurface however was getting passed a
GdkDisplay, rather than the EGLDisplay it expects. As a result the old
surface did not get destroyed and the new surface could not be created
causing rendering to freeze.
Default: avoid use of opacity for overlay scrollbars
If using the opacity CSS property the renderer cannot optimize these
handles without the use of offscreens due to the use of both a border
and rgb render node.
Instead, we can apply the alpha to the color values and get the same
effect in a way that the GL renderer can optimize without the use of
offscreen textures for a sizeable reduction in runtime overhead.

gtkscrolledwindow: Change lifetime of kinetic scroll helpers
In order to properly accumulate scroll velocities, we need to keep
the kinetic scroll helpers after we have possibly stopped them
in the process of initiating a further scroll flick.
So, instead of stopping (and destroying) those helpers on scroll-begin,
keep them until the next scroll-end if a scroll was initiated before
kinetic scroll finished. This way we can fetch the last velocity when
calculating the extra kick.
In order to ensure the helpers don't live beyond what it is expected,
we now also remove them after a finished hold event.
Fixes the accumulation of scrolling velocity on consecutive scroll
sequences.
Do not depend on the kinetic scroll helpers existing or not before
exiting the animation, as we may want to keep those a little bit
longer after stopped.

gtkscrolledwindow: Add scroll unit handling
On the "scroll" signal, the widget uses
gtk_event_controller_scroll_get_unit() to get the
scroll unit.
When the unit is GDK_SCROLL_UNIT_WHEEL, the
behavior is unchanged: the widget scrolls a
certain number of pixels at each wheel detent
click. This number of pixels is determined by the
window dimensions in get_wheel_detent_scroll_step().
When the delta unit is GDK_SCROLL_UNIT_SURFACE, the
widget directly adds the delta to the number of
scrolled pixels no matter the window dimensions.

gdk: Add enum to indicate the unit of scroll deltas
Add a new GdkScrollUnit enum that represent the
unit of scroll deltas provided by GdkScrollEvent.
The unit is accessible through
gdk_scroll_event_get_unit().
This moves a lot of the texture atlas control out of the driver and into
the various texture libraries through their base GskGLTextureLibrary class.
Additionally, this gives more control to libraries on allocating which can
be necessary for some tooling such as future Glyphy integration.
As part of this, the 1x1 pixel initialization is moved to the Glyph library
which is the only place where it is actually needed.
The compact vfunc now is responsible for compaction and it allows for us
to iterate the atlas hashtable a single time instead of twice as we were
doing previously.
The init_atlas vfunc is used to do per-library initialization such as
adding a 1x1 pixel in the Glyph cache used for coloring lines.
The allocate vfunc purely allocates but does no upload. This can be useful
for situations where a library wants to reuse the allocator from the
base class but does not want to actually insert a key/value entry. The
glyph library uses this for it's 1x1 pixel.
In the future, we will also likely want to decouple the rectangle packing
implementation from the atlas structure, or at least move it into a union
so that we do not allocate unused memory for alternate allocators.
This removes the sharing of atlases across various texture libraries. Doing
so is necessary so that atlases can have different semantics for how they
allocate within the texture as well as potentially allowing for different
formats of texture data.
For example, in the future we might store non-pixel data in the textures
such as Glyphy or even keep glyphs with color content separate from glyphs
which do not and can use alpha channel only.
This allows the gskglprograms.defs a bit more control over how a shader
will get generated and if it needs to combine sources. Currently, none of
the built-in shaders do that, but upcoming shaders which come from external
libraries will need the ability to inject additional sources in-between
layers.
If the max_entry_size is zero, then assume we can add anything to the
atlas. This allows for situations where we might be uploading an arc list
to the atlas instead of pixel data for GPU font rendering.
