If the column used for the GtkTreeView:tooltip-column contains NULL
we're already skipping a tooltip; let's ignore empty strings as well,
as an empty tooltip is pretty much pointless.

We're using [a-z] ranges with sed and grep, and POSIX does not specify
their behaviour in non-ASCII locales:
In the POSIX locale, a range expression represents the set of
collating elements that fall between two elements in the collation
sequence, inclusive. In other locales, a range expression has
unspecified behavior
-- IEEE Std 1003.1-2017, § 9.3.5 (7)
This can lead to no results, or invalid replacements, which in turn can
lead to broken builds or broken build artifacts.

When we receive a size from the move-to-rect implementation, force GTK
to continue using that size until reconfigured by move-to-rect, or
when remapped.
Fixes: #1651
On X11, the position of the menu is calculated synchronously by
gdk_window_move_to_rect(). This means that calculating the window size
when showing is too late, as that'd mean the size used when calculating
the position is out-of-date. The first time a menu is mapped, however,
the size is calculated during realization; but a window is only realized
once, so it doesn't work for subsequent maps.
Currently, this is harmless, as a GtkMenu can change its size however it
wants after it has been mapped. This, however, is problematic, as it
means the position calculated by gdk_window_move_to_rect() might no
longer be valid, or constraints made by the same function might no
longer be respected.
Thus, this is a preparation for making GtkMenu popups stay the same size
until they are remapped again at a later point.
Sometimes (read for GtkMenu on X11) it's not enough to resize on show,
and relying on the size to be calculated on realization only works the
first time a menu is popped up, so add an API that GtkMenu can use to
ensure the size of a menu is "refreshed" before passing anything along
to gdk_window_move_to_rect().
This causes window size guessing to always use the remembered size (the
size of the GdkWindow). This will be useful for menus which size is
managed by gdk_window_move_to_rect(), to avoid overriding the size
calculated by the move-to-rect implementation.
We don't need to do it, since g_clear_pointer() will do it for us, and
will also check if the function conforms to a GDestroyNotify. Using an
explicit cast will generate a compiler warning.
Now that we've switched the on and off states to gadgets, we need to
ensure that the widget's clip take into account the clip of every
gadget.
Fixes#1631
Improve overflow arrow buttons drawing on a scrollable dropdown menu:
reduce top button's margin-top to match size of a bottom button, add
margin-top for bottom button to compensate bottom margin (otherwise
button overlaps with menu content).

- it's less busy and still clearer without the label
- It may be right that color alone is a poor differentiator,
but labels do still exist for the accessible theme.
- create more contrast against the headerbar background without lowering
contrast with the label and border.
- top border shaded for extra aid of the state being pressed (in the two button scenatio)
