The root window is a fairly X-centric concept, and it
really has no place in the GtkWidget API. Plus, this
is a rarely-used one-line convenience function with
poor documentation.
Put dialogs and utility windows in the same level as normal and
toolbar windows so that Gtk can control their stacking instead of
forcing them, rather unnaturally, to be on top of all other windows,
even other application windows, even when another application has
focus.
Instead of setting "use-header-bar" from gtk_about_dialog_new(),
override its default value by inspecting the properties at constructor()
time. This makes it work from bindings as well, since they don't use the
convenience C constructor.

GtkWindow has 4 (!) APIs for setting window icons, and we
have to try them all in the right order to find the right
icon. This commit makes it so, and keeps the icon list
manipulation inside gtkwindow.c by adding a private API
for getting a single icon at the right size.

This is needed to show the gtk3-demo icon and is needed for the "Multiple
Views" demo to work. Hmm, why couldn't I do a for loop for a batch in a
property sheet ? :|
It was only done so the background would connect visually to the popover
tail, but then it brings aliasing issues when the border is drawn over the
background. Instead, overdraw the tail, so it also fills the gap left by
the border.
If pointing_to starts falling outside of the parent scrollable allocation,
the popover will be automatically hidden, and shown back again when
pointing_to scrolls back to visibility.
If the rect a handle points to starts falling outside of the parent
scrollable allocation, the handle will be automatically hidden, and
shown again when the rectangle is visible too.
When all popovers are removed on destroy(), if a popover is nested into
(eg. with relative_to within) another popover, the removal of one can
lead to the other being removed while the hashtable is being iterated,
which would lead to undefined behavior in further iterations.
Then, use a GList to store popovers, iterating can be made more resilient
on these situations, and unless on pathological cases there's not going
to be as many of those popovers as to cause performance decreases at the
times those are iterated.
