In GTK4, we are now defaulting to the OpenGL renderer with the Cairo renderer
only used as a fallback, so there is no point keeping the code paths that use
layered windows as layered windows do not work well with OpenGL nor Vulkan.
Commit e6209de962 added some checks on TranslationEntry.valid in
order to figure out whether using the new font settings or the
old g-s-d ones. However that's only set in the non-sandboxed case.
This makes sandboxed applications fallback to the old (and also
non-existing with modern g-s-d) settings, possibly resulting in
ugly defaults being picked.
Fix this by also marking TranslationEntry elements as valid when
using the settings portal, precisely those entries that we are able
to read and match with our own table.
Have an implementation of ->request_layout() and ->compute_size() for the Win32
surface backend so that we can properly display and move and resize the
windows, as we request from the Win32 APIs.
Hxndling Aerosnap properly is mostly done except for snap_up(), which needs to
to be looked at later.
In line with what is done with the Wayland backend, enable the mapped state
independently as needed from the toplevel surface presentation, and also enable
the mapped state if necessary when presenting the popup surface.
The fact that we are using gdk-pixbuf for loading files currrently does not mean we will use it going forward.
Also, "anything gdk-pixbuf can load" does not mean anything, because what gdk-pixbuf can load is a compile-time option.
As new_from_resource() will assert() if it cannot load a resource, we must be very sure that people do not use anything but PNG and JPEG for resources and the docs were not clear on that.
When destroying a wl_surface (e.g. when a window or menu is closed), the
surface may continue to exist in the compositor slightly longer than on
the client side. In that case, the surface can still receive input
events, which need to be ignored gracefully.
In particular, this prevents segfaulting on wl_surface_get_user_data()
in that situation.

In pointer_surface_update_scale(), only rescale the cursor surface when
the scale has actually changed and the cursor is on at least one output.
fixes https://gitlab.gnome.org/GNOME/gtk/-/issues/3350
Right now, this issue is not completely understood, so it might also
involve some questionable handling of cursor surface by sway/wlroots.
However, irrespective of that issue, this patch avoids unnecessary calls to the
compositor, and there should be no drawback: Whenever the pointer enters
a new output, pointer_surface_update_scale() will be called again, such
that correct scaling of the cursor is still ensured.
There is a slight difference: When the cursor leaves the last output,
previously the image was reset to scale factor 1. Now, it keeps whatever
was last. That might be more sensible than the previous behaviour,
assuming that it's likely that when the cursor enter an output again, it
has the same scaling. Alternatively, if one cares about resource usage
at this level, it might make more sense to destroy the surface than
rescaling to 1.
To support Sierra, we need to have access to pasteboard types as a
NSString. Constants are provided in later versions of macOS, but we
can emulate that with an array which is initialized on first access.
On older systems, the availability of some methods seem to be incorrect
based on Apple documentation. This works around the issue by using
the rect conversion on older systems.
On x11 toplevel layout is not created before toplevel
is presented, but GTK tries to update it on idle
which leads to a crash due to accessing property
of undefined object. Treat soon to be created layout
as a layout with default values upon creation (resizable).
These functions were not implemented when the sizing changes
landed before GTK 4 was released. This fixes an issue with non-
resizeable windows not reacting to layout changes.

According to OpenGL spec, a shader object will only be flagged
for deletion unless it has been detached; when a program object
is deleted, those shader objects attached to it will be detached
but not deleted unless they have already been flagged for deletion.
So we shall detach a shader object before it is deleted, and delete
it before the program object is deleted best.
Some GTK based applications such as Qemu UI create and manage
EGLSurfaces associated with the relevant GdkSurfaces. In order to create
an EGLSurface, there needs to be a way to pass the native window
object to eglCreateWindowSurface(). While running in an X environment,
the native window object can be obtained by calling
gdk_x11_surface_get_xid(). Likewise, the native window object can be
obtained by calling gdk_wayland_surface_get_wl_egl_window() while
running in a Wayland environment. Therefore, this API needs to be
exposed to apps.

If set to TRUE, does not call the free func for the removed items.
This can be used to move items between arrays without having to do the
refcounting dance.

Depending on the input driver, we will get XI_Motion based scroll
events for regular mouse wheels. These are intended to be handled
as discrete scroll, so detect smooth scroll events that move by
exactly 1.0 in either direction.

When being fullscreen, and wanting to unfullscreen but not caring about
whether to go unmaximized or maximized (as this information is lost), if
the GdkToplevelLayout represents the full intended state, we won't be
able to do the right thing.
To avoid this issue, make the GdkToplevelLayout API intend based, where
if one e.g. doesn't call gdk_toplevel_set_maximized() with anything, the
backend will not attempt to change the maximized state.
This means we can also remove the old 'initially_maximized' and
'initially_fullscreen' fields from the private GtkWindow struct, as we
only deal with intents now.
This is a more reliable calling point than ::resume-events, and a
good one to schedule things so they happen on a frame clock in no
special phase (Thus still fixing the original issue at 80d4a08e30)
Fixes: https://gitlab.gnome.org/GNOME/gtk/-/issues/3461
Those requests are received while dealing with the ::layout frame
clock phase, this has the unintended side effect of making the
frame clock "rewind" to handle ::flush-events again during this
frame, which delays everything and practically halves the frame
rate.
We do intend to make the motion events dispatches on the next frame,
so do this in an idle at a slightly lower priority than layout/draw,
so the ::flush-events phase is actually requested for the next frame.
Fixes: https://gitlab.gnome.org/GNOME/gtk/-/issues/3264
We don't need to go through the NSOpenGLContext for these.
We can just use the C API directly. It's also clearer what is using
CGLEnable() vs CGLSetParameter().
It was used by all surfaces to track 'is-mapped', but still part of the
GdkToplevelState, and is now replaced with a separate boolean in the
GdkSurface structure.
It also caused issues when a widget was unmapped, and due to that
unmapped a popover which hid its corresponding surface. When this
surface was hidden, it emitted a state change event, which would then go
back into GTK and queue a resize on popover widget, which would travel
back down to the widget that was originally unmapped, causing confusino
when doing future allocations.
To summarize, one should not hide widgets during allocation, and to
avoid this, make this new is-mapped boolean asynchronous when hiding a
surface, meaning the notification event for the changed mapped state
will be emitted in an idle callback. This avoids the above described
reentry issue.
We only called xdg_toplevel.(un)set_maximize() if the toplevel layout
changed, but this misses the case when the compositor had changed the
maximized state. Change it to call the xdg_toplevel request if either
the local layout changed, or if the layout differs from the current
state.
This fixes an issue where one couldn't unmaximize a window by double
clicking the titlebar that, had previously been maximized e.g. using a
keyboard binding.
Do the same for fullscreen.
This will sometimes mean a frame is skipped if a resize was requested
during the update phase of the frame dispatch. Not doing so can cause
trying to allocate a window smaller than the minimum size of the widget.
If compute_size() returns TRUE, the layout will not be propagated to
GTK. This will be used by the X11 backend to queue asynchronous resizes
that shouldn't yet allocate in GTK.
Not doing this means the next time the same surface is shown, if the
shadow size wasn't changed, it wouldn't be sent to the compositor, which
then would result in compositor deriving its own window geometry which
would include the shadow margin.
This fixes an issue where the file chooser dialog would grow each time
it opened.
The allocation of popups are part dependent of the allocation of the
root, which means the root must still be allocated when updates are
frozen, otherwise we'll try to allocate non-laid out popups.
