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.

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`

macos: prohibit fullscreen transition if in transtion
This prevents performing additional fullscreen transitions while
a transition is already in progress.

When given an invalid atom, gdk_x11_get_xatom_name_for_display can
return NULL and trigger a seg in gdk_x11_clipboard_formats_from_atoms.
Check for NULL.
Why I'm seeing a bad atom there is probably a separate question.

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.

The call to gdk_win32_clipboard_request_contentformats() can return NULL even
without an error condition being hit (such as when the system clipboard is
empty), so check whether the returned GdkContentFormat pointer is not NULL
before calling gdk_clipboard_claim_remote(), which expects it to be not NULL,
otherwise we face a warning from that funtion and the subsequent
g_object_unref().
This at least partially fixes issue #4796.
We may well be using an EGL context that does not support Desktop (W)GL on
Windows, such as in the case of using libANGLE. So, check whether WGL is
supported for this running instance before trying to query WGL extensions.
This will get rid of warning messages from libepoxy.
Otherwise a stray scroll controller may prevent others from getting hold
events, even if it always propagates scroll events and does absolutely
nothing.
We only need a C compiler and not the whole toolchain,
and gst-plugins-bad was split into libraries and plugins.
pkg-config -> pkgconf.
This should speed the CI setup up a bit.
As documented:
> Overlay children whose alignments cause them to be positioned

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.
Fixes#4783
