#5

Avoid using deprecated gdk_pixbuf_new_from_inline()

See merge request !2

Bug-Debian: https://bugs.debian.org/908745
Closes: https://bugzilla.gnome.org/show_bug.cgi?id=797137

As reported by Simon McVittie <smcv@debian.org>:

"
[…] gdk_pixbuf_new_from_inline() is deprecated.

A gdk-pixbuf maintainer recommends[1] using GBytes and new_from_bytes(), which
is also what pygobject does in its own overrides

[…]

[1] on gdk-pixbuf!17
"

This code is based by the one @smcv suggested, edited by myself to support the
case when $data is an array ref that contains unpacked bytes, like the previous
implementation did.

Use a temporary, writable directory as $HOME while running tests.

See merge request !1

Otherwise, t/overrides.t and t/zz-GtkRecentChooserDialog.t fail in a Debian
sbuild build environment, with errors such as:

  Gtk-CRITICAL **: Unable to create user data directory  '/sbuild-nonexistent/.local/share' for storing the recently used files list:  Permission denied  **  Gtk:ERROR:/tmp/buildd/gtk+3.0-3.8.4/./gtk/gtkrecentmanager.c:622:gtk_recent_manager_set_filename:  assertion failed: (priv->filename != NULL)

In gdk-pixbuf 2.38.0, the GdkPixdata introspection data was split out into its
own file.

- Tests in _Gtk3_ now require _Glib::Object::Introspection_ version
  0.043 or newer, due to the new functions that were added in that
  version; closes RT#122761

Apparently, the default main loop's event queue might sometimes already
contain events even though we did not put any in there (for example, a
settings change notification).  This caused test failures.  To avoid
this, clear the event queue before relying on its contents.

Gtk3::Container::add_with_properties, Gtk3::Container::child_get and
Gtk3::Container::child_set.

Currently, this applies to Gtk3::ListStore::insert_with_values,
Gtk3::ListStore::set, Gtk3::TreeStore::insert_with_values,
Gtk3::TreeStore::set and Gtk3::Gdk::Pixbuf::save*.
