We don't want to be responsible for duplicating the effort of the hash
table, we just want to speed up subsequent lookups. Otherwise, we risk
not marking glyph usage when tracking usage for compaction.
This required finishing up the begin_frame/end_frame semantics for
GskNglTextureLibraryw which was apparently overlooked.
The driver was changed to provide more information to the library when
beginning frames. We do not need to use end_frame so that was removed.
The frame age is the same as GL (60) but I do wonder if that is based
on seconds if we should be using something longer for situations where
we have higher frame rates.
Fixes#3771
Respect the debug settings for disabling Vulkan or GL,
and do not try to initialize those contexts. This can
be necessary to work around crashes.
Fixes: #3748
As long as we can create a GL context, pass one to
gstreamer. This at least gets us GL textures with
the ngl renderer, the previous code was arbitrarily
refusing that.
Setting up check or toggle button group relationships
in a cycle will lead to lockups. Add a warning about
this, and catch the simplest case with a precondition
check.
Fixes: #3763
Apparently, by comparing with the other backends, we should not call
_gdk_win32_append_event() after calling gdk_scroll_event_new() but we should
call it after calling gdk_scroll_event_new_discrete(), which was why we didn't
restore the cursor after we scroll using the mouse wheel and didn't manage to
remove the shade that appears after we scrolled to the very top or very bottom.
Also, as suggested by the reporter, use IDC_SIZEALL for the system cursor that
we fall back to if no cursor theme is installed, as with other Windows
programs.
This should really fix issue #3581.
If cairo is a subproject, it's not necessarily installed when gtk
is built. In the build tree, libcairo-script-interpreter is not stored
in the same directory as other cairo libraries.
If cairo is a subproject, it's not necessarily installed when gtk

a directory called 'cairo'.
GTK traditionally lets you activate keyboard shortcuts
even if they are for a non-active layout. But it is meant
to only activate with a keysym from a non-active layout
when that symbol is not present in the current layout.
That last condition was lost when key event handling
was redone for GTK4. Bring it back.
This makes sure that we don't have cursors disappearing on Windows upon
scrolling because we can't find a cursor that exists on the system during
a scroll, and unlike GTK-3.x, we do not default to the arrow pointer on GTK4.
Just mimic what we have on X11 and Wayland: the trusty standard arrow pointer.
Fixes issue #3581.
We were calling _gdk_surface_update_size() every frame, even if the
window size didn't change. This would cause us to discard all cached
buffers and redraw the whole screen.
This was BAD.
