When we are not doing baseline alignment, don't pass
a baseline to the allocated widget. This helps because
a number of widgets (GtkLabel, GtkEntry, etc) always
position their text on the given baseline.

gdk/x11: Invalidate whole surface after size change
The Expose events following a ConfigureNotify may arrive at
a time that we did not resize the surface yet, making these
expose events a no-op. Even though gsk/gtk take care of the
window content itself, this might lead to unrendered portions
of the window shadow.
This may be seen with GSK_RENDERER=cairo and GDK_BACKEND=x11,
attempting to tile a window (e.g. gtk4-demo) left or right.
The window will show black rectangles or other artifacts in
the window shadow areas that correspond to the newly painted
portions (as the window needs to expand vertically).
In order to fix this with a similar behavior to Wayland,
consider ourselves the whole surface invalidated after resize,
in order to ensure everything is painted from scratch.
Drop the section that talked about main and how to update
local checkouts - its been 2 years, people should have gotten
around to it by now. Add some general git hints instead.

wayland: Set EGL swap interval to 0.
There's no need for EGL to do any timing, we do it in GTK already.
This fixes hangs in Mesa when we hide a surface after a SwapBuffers()
but before the frame callback arrives.
If we then reshow the surface and immediately render to it, Mesa would
still have a frame callback from before the hiding and forever poll()
waiting for the compositor to send the callback.
donʼt mention its renamed successor either, as that has its own section
later. We could have another sentence paragraph like ‘In the case of
GtkBox, the pack methods have been renamed to X and lost the trailing
arguments Y’, but that wonʼt help people prepare still on GTK3, which is
the point in the affected section… so just remove the misleading relic.
When adjusting allocations, treat BASELINE more like CENTER
than like FILL. The results are better, in particular for
controls like entries or switches, which we never want to
scale up vertically, but still want to align to the baseline.

gsk: Synchronize when using textures
Pass the GLsync object from texture into our
command queue, and when executing the queue,
wait on the sync object the first time we
use its associated texture.
Add a new function to TextureBuilder that takes a GLsync that
requires internal code to wait on before using the texture.
Somewhat sneakily, we don't take the sync if syncs are not supported by
the current GL context.
As public API has no code to query the sync for the destroy notify, this
is fine and it means we don't have to do the check every time we want to
call gdk_texture_get_sync() internally.

win32: Refactor context creation
This refactor achieves the following:
* check GL version against proper matching context version
In particular, for legacy contexts, we now actually check
* make sure the actual version is set, even for legacy contexts
* make sure set_is_legacy() is set properly

glcontext: assert all contexts set the version on realize()
Now that all contexts do that, insist that they keep doing it.
And because they keep doing it, we can support querying the GL version
from gdk_gl_context_get_version() without requiring the context to be
made current.

egl: Make sure highest possible GL version is created
The EGL spec states:
The context returned must be the specified version, or a later
version which is backwards compatible with that version.
Even if a later version is returned, the specified version
must correspond to a defined version of the client API.
GTK has so far been relying on EGL implementations returning a
later version, because that is what Mesa does.
But ANGLE does not do that and only provides the minimum version, which
means Windows EGL has been forced to use a lower EGL version for no
reason.
So fix this and try versions in order from highest to lowest.

treelistmodel: Delay notifies from TreeListRow
Don't notify during destruction, notify afterwards.
This way we don't call into user code from a half-destructed node.
Note that this changes the order in which those notifies happen when
collapsing a large tree: From parent node before child nodes to child
nodes before parent node.
No actual use case for this, just thought it would be safer.

treelistmodel: Be safer during collapsing
While we are collapsing a subtree, some signal handlers may not be
disconnected while we are doing this. By adding this check and not
giving those nodes no longer access to the model, we can stop it from
modifying it while we are trying to collapse stuff.
