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.
gdkwindow: Allow gdk_window_set_opacity on non-native children
We now store the current opacity for all windows. For native windows
we just call into the native implementation whenever the opacity changes.
However, for non-native windows we implement opacity by pushing a
second implicit paint that "stacks" on the existing one, acting as
an opacity group while rendering the window and its children.
This works well in general, although any native child windows will of
course not be opaque. However, there is no way to implement
implicit paint flushing (i.e. draw the currently drawn double buffer
to the window in order to allow direct drawing to the window).
We can't flush in the stacked implicit paint case because there
is no way to get the right drawing behaviour when drawing directly
to the window. We *must* draw to the opacity group to get the right
behaviour.
We currently flush if:
* A widget disables double buffering
* You call move/resize/scroll a window and it has non-native children
during the expose handler
In case this happens we warn and flush the outermost group, so there may
be drawing errors.

gdkwindow: Do not rely on a previous slave device when updating grab
_gdk_display_device_grab_update does not support passing in NULL for the
source device. If we don't have a slave device (saved in the pointer info)
then do not try and use that NULL pointer for the source_device.
This bug appeared in the Wayland backend where we (currently) only have master
devices exposed and as such no slave device is ever saved.

Remove a no-op AtkAction from GtkRange
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.

It turns out that we just started using AX_PROG_CC_FOR_BUILD, which
for some reason requires AC_CANONICAL_TARGET. That seems wrong to
me, but for now, lets just keep using it.
This autoconf macro should only be used for building compilers
(or compiler tools) for a specific target. The current effect of
it in GTK3 is that it causes various executables like gtk3-demo
to be prefixed with $target- when the --target configure flag
is set or when cross-compiling. When cross-compiling GTK3 on
Linux for the Win32 target this causes the gtk3-demo binary
to be named i686-w64-mingw32-gtk3-demo.exe instead of just
gtk3-demo.exe (like it was before commit 53083ea7b423482b)

scrolledwindow: make gtk_scrolled_window_add() smart
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().

cssimage: Only load image data when needed
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.

css: Split out GtkCssImageSurface
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...

cssimage: Store the URI we're loaded from
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.
