If you set GDK_SCALE=2 in the environment then all windows will be
scaled by 2. Its not an ideal solution as it doesn't handle
multi-monitors at different scales, and only affects gtk apps.
But it is a good starting points and will help a lot on HiDPI
laptops.
This code is a relic from GTK2 days and should not be necessary anymore,
as code now makes sure to only copy those parts of the window that are
not overlapped by parent windows.
By deleting it we fix potential issues with composited and translucent
windows copying the wrong data.

Moving the direct-access redefinitions of various macros
to gdkprivate-x11.h and use that header throughout in x11/.
Also remove a workaround for a long-fixed X server bug.
The window move code needs special attention for multiple reasons:
- invalid areas for expose events need to be modified
- self-copy is not supported by Cairo
- in X11, copying from an overlapped Window might cause unexposed areas
to be copied in, spo expose events for those need to be generated.
This was all special cased in various parts of the code. By making it an
explicit vfunc, we can work around it.
Includes fixing all callers to use the cairo region API instead. This is
usually just replacing the function names, the only difference is
gdk_region_get_rectangles() being replaced by
cairo_region_num_rectangles() and cairo_region_get_rectangle() which
required a bit more work.

The X11 queue_translation operation uses NextRequest to get the serial
of the XCopyArea operation where the translation should end. However,
if the gc passed to gdk_draw_drawable has a non-flushed clip region
(which it commonly has now for the window clipping) then the next
operation will be the GC flush, not the XCopyArea.
To handle this right we now pass in the GC to be used to
queue_translation and ensure that it is flushed before calling
NextRequest().
To avoid drawing the window background of other windows in the area
where the window was we set the bg to none recursively. However, this
is quite costly it the moved window has many siblings. Furthermore, it
is uncommon that siblings overlap, so this cost has little gain.
So, we only set bg None on the parent, which means that there will
be some more flicker in the uncommon case of overlapping siblings.
All the calls that unset private->parent failed if that was
not a native window (impl), instead we need to find the impl window
for the parent. Add some helper functions for this and use them.
For move/resize of child windows, we really need to recursively unset
on the parent, because moving the window could expose other native
children of the parent.
In do_shape_combine_region, only unset background if we're changing
the bounding shape (i.e. not the input shape)
move_region_on_impl() - doesn't need to copy anything if dx/dy == 0
Ensure that we queue an update when invalidating an empty area but we have outstanding moves
Temporarily unset background when moving native child windows
The history before this was kind of twisted as several different
approaches were tested, so that was all squashed into this initial
commit to hide the uninteresting changes and files that were later
removed.

Abstract some GdkWindow API into an interface that the backends
must implement. (based on a patch by Alex Larsson)
* gdk/Makefile.am: Add gdkwindowimpl.[ch]
* gdk/gdk.symbols: Move symbols around.
* gdk/gdkinternals.h:
* gdk/gdkwindowimpl.[ch]: Move some of the GdkWindow API we require
from the backends to a GInterface that the backends should implement
instead.
* gdk/gdkwindow.c: Provide some of the GdkWindow public API as a
wrapper call around the GdkWindowImpl interface vtable.
* gdk/x11/gdkevents-x11.c:
* gdk/x11/gdkgeometry-x11.c:
* gdk/x11/gdkprivate-x11.h:

* gtk/gtklayout.c (gtk_layout_realize),
* gtk/gtkiconview.c (gtk_icon_view_realize),
* gtk/gtktreeview.c (gtk_tree_view_realize): Set the background of
the clip windows to NULL, since they are generally invisible and
don't have EXPOSURE set, which means they temp-unvlicker code
doesn't apply to them.
* gdk/x11/gdkgeometry-x11.c (_gdk_window_move_resize_child): Unset
the background of the parent window during resizing. Invalidate
the uncoered area of the parent window. Bug 341332.

function which can be used to implement scrolling in
non-window widgets. (#135165, Søren Sandmann)

Make PLT-reduction work with gcc4, and don't include
everything in gdkalias.h:
* gdk/gdk.symbols: Group symbols by header and source file.
* gdk/makegdkalias.pl: Protect definitions by the same
preprocessor symbols used to guard the headers. Move
the alias declarations to a separate file which is
produced when calling makegdkalias.pl -def
* gdk/Makefile.am (gdkaliasdef.c): Add a rule to generate this
file.
* gdk/*.c, gdk/x11/*.c: Include gdkalias.h after the other
headers, include gdkaliasdef.c at the bottom.

Add hidden aliases for exported symbols which are
used internally in order to get rid of many PLT
entries. (#145519, Arjan van de Ven)
* gdk/Makefile.am: Add rules to generate gdk.def and
gdkalias.h from gdk.symbols, and make make check check
the abi with abicheck.sh.
* gdk/gdk.symbols: New file. Definition of the GDK ABI.
The file can be processed by cpp to filter out certain
subsets of symbols.
* gdk/abicheck.sh: New file. Script to check the actually
symbols exported from libgdk-x11.2.0.so against the symbols
found in gdk.symbols.
* gdk/makegdkalias.pl: New file. Perl script to generate the
header containing the alias definitions for internally used
exported symbols from a list of symbols.
* gdk/*.c, gdk/x11/*.c: Include gdkalias.h
