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.

_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.

The following patch added a dependency on a new API first available in that

Add accessibility for GtkLevelBar and value test
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.

This reverts commit cd98eb15cb.
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 53083ea7b4)
