An empty container has the same effect as transparency
with the cairo renderer, but creates black with Vulkan.
To avoid this, explicitly use a transparent color node.
This fixes the css blendmode example in gtk4-demo with
the Vulkan renderer.
As Timm Baedert pointed out, the previous fix made the
menubar go on top of popovers, which is just wrong. Instead,
make gtk_window_snapshot handle all direct children of the
window, taking care to stack popovers correctly.
This is important since _push_state returns a pointer into a GArray
which could be invalidated and point to garbage after the subsequent
push_state call.
This is used for example in the source tab of gtk4-demo.
It broke because GtkScrollbar no longer is a GtkRange,
but rather has one. So we need to forward the signal.
It was selecting paned separator, which means any separator at any level
of descent within a paned, including the toplevel container in GEdit.
We need to be more specific and only select the relevant separator that
is the direct child of the paned. This is what Adwaita does.

Nulling priv->button in _unset_tree_view() is asymmetrical: we create
it via init(), not _set_tree_view(), so we shouldn’t null in the latter.
Worse, doing so manifests in criticals + a SEGV easily with basic use of
testtreecolumns, removing the TVC from a TV then trying to add it to one
Finally, the wrong null-out meant dispose() failed to unref the button,
so it leaked.

This patch makes that work using 1 of 2 options:
1. Add all missing enums to the switch statement
or
2. Cast the switch argument to a uint to avoid having to do that (mostly
for GdkEventType).
I even found a bug while doing that: clearing a GtkImage with a surface
did not notify thae surface property.
The reason for enabling this flag even though it is tedious at times is
that it is very useful when adding values to an enum, because it makes
GTK immediately warn about all the switch statements where this enum is
relevant.
And I expect changes to enums to be frequent during the GTK4 development
cycle.
GtkCellArea uses event coordinates (thus in treeview relative
coordinates), but calculations used to happen in bin window coords.
We can just offset the cell area by the bin window, fixes cell
renderer activation and edition.
If the column is not clickable, it may make some sense to stop
event propagation here for button events. However motion events
should be left alone.
Fixes treeview column resize pointer cursors, since that's
implemented up the bubbling phase in the treeview.
The operations rely there on bin window relative coordinates, but we
are receiving GtkTreeView relative coordinates there. Fixes clicking
on treeview expanders, which was offset by visible headers.
-Wint-conversion is important because it checks casts from ints to
pointers.
-Wdiscarded-qualifiers is important to catch cases where we don't
strings when we should.
The border and icon highlight are useful feedback that was defeated by
CSS precedence. It worked for .titlebuttons due to their implementation,
but the same was not true for custom .flat buttons. This makes it so.

When the window was backdropped, they suddenly regained their border.
This was clearly not intentional or of any practical use to anyone.
Shuffle around some selectors so that the backdrop ones do not override
the flat ones and make the borders magically reappear when backdropped.
Note that, whereas standard titlebuttons get the border on :hover, other
.flat buttons in the headerbar do not. That should probably be fixed too

They were hard-coded to a transparent black, but that is our bg colour
in HC Inverse, so windows stacked on top of each other or a dark
background blended together into a mush.
Fix this by making the $_wm_border* colours relative to the fg colour,
so that HighContrastInverse gets borders that are transparentised white.

A missing decoration selector meant that we got a solid black background
behind the rounded corners of the dialog.
Copy the equivalent code from Adwaita, including nicely rounding the
focus outline too (& sorry, but this needs more newlines to be readable)
There were various problems, like only selecting on .tooltip and not the
widget node tooltip, not being specific enough for tooltip.csd, etc. So,
specific theming was absent, and default popup window styles got applied
This commit copies in the better working tooltip CSS from Adwaita, but
applies a couple of changes to make it work better in the HC themes:
• Reduce the transparency of the tooltip, so we achieve higher contrast
• Drop the black text-shadow, as it is not useful on this more black bg
Note: we may then need to re-add some of this to the .tooltip class. But
it is unclear what needs done there. While Adwaita is not doing it, we
are better not to confuse by keeping it in HC only; we should try to be
as close as possible, to make it easier for HC to keep up with Adwaita.
