This adds a way to get the gtk_widget_set_opacity liike behaviour
of retargeting GdkWindows and exposing every child in ::draw, without
actually having an alpha. This is needed if you're doing more complex things
such as cross fading of widgets.
We do this as a hack by using opacity values that round to 255 yet not
really 1.0 in order to avoid having some magical API call for this
mainly internal call.

Sink the GtkEntry assigned to the private structure of GtkCellRendererText
before signals containing it as an argument are sent out. This keeps
language bindings from sinking the reference and then destroying the entry
when the signal closure is finished.

When calling gtk_widget_draw() on the entry gtk_cairo_should_draw_window()
will return TRUE for all windows. This is used when rendering a widget to
somewhere other than the screen, and its now used for transparent widgets.
This caused the texthandle to always draw itself and terminate the draw
handler for the entry.
Instead we now only draw the markers when really visible, plus we return
FALSE to avoid stopping the entry drawing.

This adds gtk_widget_get/set_opacity, as well as a GtkWidget.opacity
property. Additionally it deprectates gtk_window_get/set_opacity and
removes the GtkWindow.opacity property (in preference for the new
identical inherited property from GtkWidget, which should be ABI/API
compat).
The implementation is using the new gdk_window_set_opacity child
window support for windowed widgets, and cairo_push/pop_group()
bracketing in gtk_widget_draw() for non-window widgets.

This replaces the previously hardcoded calls to gdk_window_set_user_data,
and also lets us track which windows are a part of a widget. Old code
should continue working as is, but new features that require the
windows may not work perfectly.
We need this for the transparent widget support to work, as we need
to specially mark the windows of child widgets.

The "activate" action here did not do anything.
It is possible we actually want to have some actions here,
like "step-up", "step-down", "page-up", "page-down", etc.
For now, just remove the AtkAction implementation.

There's really no reason why we shouldn't automatically create a
GtkViewport when the widget added to GtkScrolledWindow is not a
GtkScrollable, instead of just printing a g_warning.
Copy the viewport special case into the scrolled window implementation
of gtk_container_add().

Saves ~6MB of memory per application in the Adwaita I am using - at
least until the app starts using all the images in the theme, because
the code doesn't discard images yet once they were loaded.

This is essentially a GtkCssImage for a cairo_surface_t and is a pretty
much straight up copy of GtkCssImageUrl. But we want to implement lazy
loading and animations, so GtkCssImageUrl is going to gain new
features...

I'd like to use it when printing the value, but I haven't found a way to
do that sanely yet, as I'd need to be able to print relative paths for
make check to work (otherwise the srcdir would blow things up). And we
use a GString to output to, so there's no way to attach a base dir to
that.
If anyone has an idea how to achieve that, poke me. Having the real
filename in debug prints sounds like a very good idea to me.

Commit ddceddaa84 removed the call to
gtk_style_context_set_background() in favour of always rendering it with
gtk_render_background() during the draw vfunc.
This has the side effect of making the backing window always
transparent, which blocks GTK from applying some optimizations during
the paint cycle. The result is that, especially in clutter-gtk
applications, scrolling performance gets really bad.
This commit partially reverts ddceddaa84
and changes the code so that both gtk_style_context_set_background() and
gtk_render_background() are called

gtk_tree_drag_source_drag_data_get's GtkSelectionData argument should not be
marked as (out) because:
a) GtkSelectionData is semi-private (it's declared in gtkselectionprivate.h),
and thus gobject-introspection has no knowledge of its fields or its size.
There is thus no way for language bindings to allocate GtkSelectionData.
b) Even if it was possible for language bindings to allocate GtkSelectionData,
a zeroed-out instance thus created would not be usable with
gtk_tree_drag_source_drag_data_get. As far as I can tell, you need to
initialize its "target" member to the GdkAtom of "GTK_TREE_MODEL_ROW".
Language bindings have no way of knowing this, of course.
