we now use gdk_offscreen_window_set_embedder() instead of a signal
to get the parent. This also replaces set_has_offscreen_changes.
Rename "parent" in all embedding related names to "embedder" to make it
more obviously different than the normal parent.
Rename gdk_window_get_offscreen_pixmap to gdk_offscreen_window_get_pixmap
to match the other offscreen calls.
Rename gdk_window_offscreen_children_changed to gdk_window_geometry_changed
as this is more descriptive.
You can call this if you have offscreen children and the geometry of
them changed. This will cause re-picking of the active window sending
enter and leave events as needed.
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.
3 signals are for offscreen windows
get-offscreen-parent: Get the parent window an offscreen is embedded in
to-parent: Convert coordinates from offscreen to parent
from-parent: Convert coordinates from parent to offscreen
1 signal is for the window embedding offscreens:
pick-offscreen-child: This picks what (if any) offscreen is at a specific position
The last signal is only used if you call gdk_window_set_has_offscreen_children
to tell gdk that the window has embedded offscreen children.
Add get-pointer signal for offscreen window pointer getting
Apps using offscreen windows can connect to get-pointer on offscreen
windows in order to make gdk_window_get_pointer() return correct
values.
Add get-offscreen-parent signal
Add signals for from-parent and to-parent coordinate mapping
Add pick-offscreen-child signal
Unfortunately the old GdkWindowObject is public and accessed
from macros, etc. So, we publish a limited copy of GdkWindowObject
and use the full one internally when building gdk.
In the new world offscreen windows are not put in the hierarchy, but are
rather toplevels for themselves. Offscreen hooks don't make any sense
in this model.
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.

Change all references of GIMP Toolkit (and variations of it)
to GTK+ Toolkit, showing no mercy at all to our beloved

* gdk/gdk.h: define __GDK_H_INSIDE__ around including all other
headers.
* gdk/gdkenumtypes.h.template
* gdk/gdk*.h: add single-include guards that #error out if
GTK_DISABLE_SINGLE_INCLUDES is defined and any of these files is
included individually. Also removed some redundant includes and
did some tiny trailing whitespace removal that's not worth to
commit separately.
* gdk/gdkprivate.h: include <gdk/gdk.h> instead of individual
files.
* gdk/win32/gdkwin32.h
* gdk/x11/gdkx.h: only include <gdk/gdkprivate.h> and remove all

* Applied pixmap redirection patch by Alexander Larsson with
various updates from:
Bug 318807 – Offscreen windows and window redirection.
Updates:
* updated docs to mention "Since 2.16".
* tests/testgtk.c: fixed snapshooting pixmap leak.
convert pixmap to pixbuf after snapshooting, to compensate for different
bit depths (occurs when snapshooting ARGB visuals and displaying the
pixmap in an RGB visual).
* gdk/gdkwindow.[hc]: made GdkWindowRedirect private.
* gdk/gdkwindow.c: removed damage idle handler, there's no aparent
need for it. enqueue damage notification as GDK_DAMAGE events
for each painting redirection at the start of the event queue.
consider windows with a redirection fully visible when invalidating,
and when updating from backing store. cleaned up stale variables.
* gdk/gdkevents.c: added _gdk_event_queue_prepend().
* gtk/gtkwidget.c: fixed coordinates for !NO_WINDOW widgets in
gtk_widget_get_snapshot; this fixes garbage snap offsets for gammacurve,
tree, drawingarea, text, handlebox, etc.
clip the redirected window hierarchy to window sizes, the visible
rectangles don't need to be taken into account here.
extended snapshooting docs to recommend gdk_pixbuf_get_from_drawable()
in case pixmap visuals could mismatch.
* gdk/x11/gdkwindow-x11.c: removed _gdk_windowing_window_get_visible_rect().
Base patch:
* tests/testgtk.c: add a "Snapshot" test to demonstrate snapshooting
of possibly obscured widgets into an offscreen pixmap.
* gtk/gtkwidget.[hc]: add GtkWidget::damage-event signal, add
gtk_widget_get_snapshot() to render a widget's contents to a GdkPixmap.
* gtk/gtkmain.c: dispatch GDK_DAMAGE events.
* gdk/gdkwindow.c: moved outer gdk_window_new() and gdk_window_reparent()
implementations here, adapted them to propagate redirects to child windows.
gdk_window_end_paint(): copy repainted window contents to redirection pixmap,
clipped to visible region. queue GDK_DAMAGE event delivery.
gdk_window_redirect_to_drawable(): install window painting redirection.
gdk_window_remove_redirection(): remove previously installed redirection.
* gdk/x11/gdkwindow-x11.c: added _gdk_windowing_window_get_visible_rect(),
renamed _gdk_window_new() and _gdk_window_reparent().
* gdk/gdkwindow.h: added GdkWindowRedirect* to GdkWindowObject, export
gdk_window_redirect_to_drawable() and gdk_window_remove_redirection().
* gdk/gdkevents.h: added GDK_DAMAGE event type.
* gdk/gdkevents.c: extract time and state from GDK_DAMAGE events.
* gdk/gdkinternals.h: added internal prototypes.
