When printing a "compound selector", make sure the name and universal
selectors are printed at the beginning and class, id, etc. selectors are
printed last.
If the svg pixbuf loader is not available, we end up with criticals
from gtk_css_image_icon_theme_draw because gtk_icon_info_load_symbolic
returns NULL without setting an error.
Avoid this by propagating the load error.
gdk_pixbuf_get_from_window() paints the given window onto a new cairo
surface. Create that new surface with the same device scale as the
window so that the result is not scaled down on hidpi screens.

Sadly, interned string properties cannot be handled generically
at all - GObject insists on inserting a strcpy in any attempt
to set a string property with generic api, destroying the
internedness of the string.
Therefore, we have to special-case GtkCssNode in the property
editor code :-(
This changes widget paths for widgets with a CSS name to return that CSS
name, now that we have added API for it.
This means that style properties are now matches using the CSS name.
Also fix the theme to use the correct name when matching style properties.
... and gtk_widget_path_iter_get_object_name(). This allows applications
that still use widget paths to use the new object names to get the
correct styling.
Mutter and webkit-gtk are examples here.
The search window of a tree view was implemented by showing without
making it visible by by positioning it outside the screen edge. This is
not possible on Wayland, so implement another method for being able to
enter text into a non-visible entry.
The new method is implemented by, before showing the window, pass the
key event directly to the IM context backing the entry. If the key
event triggered the context to commit new text or change the preedit
content, the search window is shown, and from that point the key events
are forwarded directly to the entry widget.

If a GtkMenu (or something else that is mapped as a xdg_popup) tries to
use a subsurface window as a parent, it will be terminated by the
compositor due to protocol violation. So to avoid this, if a parent
window is not a xdg_popup or xdg_surface, i.e. a wl_subsurface, then
traverse up the transient parents until we find the right popup parent.

Take into account and compensate for the size of the client side
decorations widgets in gtk_window_move() and gtk_window_get_pos()
including gravity.
Bugzilla: https://bugzilla.gnome.org/show_bug.cgi?id=756618
When client side decoration is used, the size passed to
gtk_window_resize() or retrieved from gtk_window_get_size() for top-
level windows also accounts for the client side decorations widgets
such as the title bar or the shadow borders.
Add up the size of these additional controls to the given size to get
the size expected.
