The change in 03213b9509 changed the rules
as to when CSD can be enabled, but it also unconditionally enables CSD
with the implicit assumption that client-side shadows were the real
issue, and that we could work around that by drawing our own borders.
This also means that setting a titlebar for a GtkWindow will enable CSD
unconditionally.
In reality, some window managers (like Matchbox) *only* support
server-side decorations, and will ignore all hints to the contrary, to
the point of drawing decorations at random locations on top of the
window.
Since CSD are enabled unconditionally, the GTK_CSD environment variable
is also not a suitable escape hatch.
In the grand tradition of asking ourselves if we should do something
just because we can, we should split the environment checks from the
checks on what the user requested; by doing that, we can also check
when enabling client-side decorations, and ideally bail out if needed.

Text insertion/pasting might trigger scroll, so we'd have to wait
until the text was revalidated and the scrolling truly happened
before we can check the new handle(s) position.
Nowadays (and for quite some years now) we rely on GdkEventGrabBroken
events to be received. This fake button event seems a remnant of
the early Gtk 2.x days, and is currently even inconsistent with our
event delivery model, so just remove it.

When recent files are not supported in gvfs, or turned off by
settings, we should not try to load them even if the startup
mode says so. This prevents inconsistency with the places
sidebar where 'Recent' will not appear in this case.
This applies the proper CSS child ordering semantics using GtkCssNode to
GtkListBox. You can now use :first-child, :last-child, :nth-child(), and
:last-nth-child() selectors.
For example, this allows styling row separators using CSS while ignoring
the separator on the last row.
GtkListBoxRow {
border-bottom: 1px solid @borders;
}
GtkListBoxRow:last-child {
border-bottom: none;
}
When the sort ordering of the listbox changes, we also update the CSS
node ordering.
When interpolating the stack size, we compute the current size by using
the prefered/minimum current size and the last size. We can't use the
last_visible_surface_allocation because that is not available until the
first _draw call and it doesn't include the child's margins.
