Don't make the popup follow the slider while it is open; that
makes interaction with it unnecessarily hard. Also move all the
popups inwards a little bit, so they are not flush with the
scales, which looks untidy.

We were not taking the scrollable borders into account when
requesting size for the scrolled window, which could lead
to underallocating the scrollbars at size allocation time
when we *did* take the borders into account.
This is most notable with treeviews, where we have the
headers as borders, and was causing the treeview-crash-too-wide
reftest to fail.
The tree walk holds a tree iter, which will become invalid
when we either remove the row that it points to or remove
all rows.
Reset the tree walk in those cases to avoid a crash that
was pointed out by Bastien Nocera.
This widget is a bit unusual in that it is a box that acts as
the drop target, while the visible content is a child of the box.
Propagate :drop(active) to the child to make the highlight visible.
We previously considered any click inside the trough if it
hit an area that the slider might cover. Bring this behavior
back; the trough of scales is otherwise just too narrow to
hit easily with a click.
Consider this bug:
1. Open a file chooser; switch it to $HOME
2. Start typing "~/Dow" with some file that *does* exist in your $HOME
3. Delete the inline-completion selection (e.g. the "nloads" after "~/Down").
4. While you are at "~/Dow_" hit Tab. No completion will occur.
This happens because of the following.
Say the GtkFileChooserEntry is in the process of loading $HOME,
because _set_base_folder() was called. If the entry contains no text,
then the FULL_PATH_COLUMN of the file system model will be set to
unprefixed filenames from $HOME, like
.ssh/
Documents/
Downloads/
somefile.txt
Later we avoid reloading the folder if g_file_equal(old_folder, new_folder).
However, the FULL_PATH_COLUMN gets populated in completion_store_set()
out of the actual filenames that GIO returned, plus the chooser_entry->dir_part.
If the user starts typing "~/Dow" then dir_part changes to "~/", *but*
the folder won't be reloaded since it is also $HOME. However, the completion
machinery assumes that FULL_PATH_COLUMN will contain prefixed entries like
~/.ssh/
~/Documents/
~/Downloads/
~/somefile.txt
So, we add an invariant that chooser_entry->dir_part and
chooser_entry->current_folder_file must change at the same time, and
must not get out of sync: If any of them changes, then the
completions are regenerated.
The adjustment double properties allow values from -G_MAXDOUBLE
to G_MAXDOUBLE, which leads to overflow when calculating
max - min / 10. To avoid that, simply use a fixed page_size of 1.0.
The contents node was not getting state updates at all, and the
trough node was missing some state updates as well, because we
were not calling update_trough_state() in all the places where
it is needed.
...hopefully when needed.
By default I assume a left hand side placement on ltr languages
and the opposite in rtl, for other placements left/right style
classes can be used.
Under Wayland, popovers use subsurfaces, and we end up getting
configure events for these delivered to the toplevel they're in.
To avoid triggering resize loops, ignore configure events that
are not for the toplevel window itself.
