If the tablet gets removed/freed while there are pad events in flight,
we leave a dangling pointer from the pad to the tablet, which may
lead to invalid reads/writes when handling the pad event(s).

Once upon a time, there was a function called gdk_event_get_scroll_deltas().
It returned %TRUE when an event had scroll deltas and that was used as the
condition to decide whether to push scroll deltas to the scroll history,
even when the both deltas are 0 for the stop event at the end of scrolling.
When GtkScrolledWindow kinetic scrolling code was adapted for
GtkEventControllerScroll, it was replaced with a (dx != 0 && dy != 0)
check. This prevented the stop event from getting into the history, and
instead allowed non-smooth scrolling to affect the history as they have
synthetic deltas with one of the values being -1 or 1 and the other on 0.
Instead, check the direction as we already have it as a local variable.
To avoid making this mistake again, add a static assertion that the
enum is in sync with gtk_license_info, and use the length of
gtk_license_info for the precondition check.

Reading form the back buffer is not allowed on software renderers,
and this is reported by the buffer age, so reading from GL_BACK
should not be done when the age is 0
Closes#64
On touch, the popup shown shall contain the 'select-all' button
only if a selection is in progress and if the entry is editable.
Let the button be shown always if selectable so that it’s more helpful.
When the code for this was copied from nautilus,
we forgot to adapt it for running in a library
instead of an application - gettext() doesn't work
in a library.

Commit 07beb6dba2 made GtkAppChooserWidget useful with no content-type,
however when used in a GtkAppChooserDialog, this will lead to a confusing
"Opening (null) files" subtitle.
Fix this by omitting the subtitle altogether in that case.
currently when mouse clicking on a column header
to sort it it is grabbing keyboard focus, this
should not happen, keyboard focus should remain
where it was before. This can be seen on the
GtkFileChooser widget, when having the keyboard
focus on the file list items and clicking on a
column header to sort it the keyboard focus is
now on the header.
GtkMenu under X11 cannot handle touch events properly,
so just disable touchscreen grabbing for it, which makes
it fallback to pointer emulation.

menu: Fix grab on other backend
They use powershell instead of cmd.exe, use the tag win32-ps instead of win32,
and run Windows 2016 instead of 2012r2.
The old runners will be switched off in the comming weeks.
This is a possible fix for https://gitlab.gnome.org/GNOME/gtk/-/issues/2657
Use a NULL return from g_file_query_info_finish() to detect cancellation
of the query, and avoid derferencing a stale pointer.
Instead of hardcoding gtk-xft-antialias, use SPI_GETFONTSMOOTHING to
determine whether antialiasing is enabled.
Make gtk-xft-rgba query more complex - try to determine display
orientation, then use that to rotate subpixel structure. This
won't help with monitors that have naturally vertical subpixels,
but should improve things for monitors that are rotated (as long
as Windows display settings are adjusted accordingly).
Partially fixes#1774
This reverts commit fc2008f240.
Turns out, we *don't* have code to maintain Z-order. Restacking
code is not doint that, it just enforces a few weird Z-order-related
behaviours.
