MacOS provides the NSEventTypeMagnify which is very similar to the
Gtk ZOOM gesture and NSEventTypeRotate which is very similar to the
Gtk Rotate gesture. Those two event sequences are translated to a
sequence of GDK_TOUCHPAD_PINCH events. This sequence is then detected
in the upper gtk layers as Gtk Zoom/Rotate Gestures.

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.
When compressing window state events, we didn't free the discarded
event after removing it from the queue, causing us to leak it. This
commit makes sure to free the discarded event after unqueuing it.

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.
