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.
Backends that support native window background setting (and that clears
new window areas to this color/pixmap) should set this to true.
Currently only X11 supports this.
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().
Last commit was bad, as it didn't clip against client side
children. This implements such clipping first and then
only clears the rectangles that need to be cleared.
We want to be able to map any window coordinate to a root coordinate, not
just the origin, because you can't rely anymore on a simple translation
from window coordinates to parent with offscreen windows. This lets
us e.g. pop up menus in the right place even if they are popped up from
a no-window widget.
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:
* gdk/x11/gdkwindow-x11.c:
* gdk/x11/gdkwindow-x11.h: Update the X11 backend to implement
the GdkWindowImpl interface.
