The custom colors are now pushed over to the right as new ones
are added, and everything beyond the 9th row gets dropped.
Customized colors are added to the custom colors array.
There's no reason this should be a focus ring rather than an actual
frame. In the past this was probably used to get a dashed effect, but
now we even support that natively for borders.
This fixes issues where the new default bg of transparent
didn't work, making offscreen windows black.
I don't think this is a practical performance problem.
Offscreen windows are rarely used and generally used for
graphics tricks like alpha anyway.
use direct access to the RBTree instead of fiddling with the path.
Removes the lat caller of get_index() and with it count_rows(), so those
are gone now.
Refcounting behavior kinda requires that we track of accessibles until
the row goes away. This is necessary for reference handling and for some
assumptions that atk-bridge does.
When moving a page around, all children changing their position
need to be notified.
There are still other places where proper notification is missing
(drag 'n drop, etc.)

Unsetting the widget causes events to get emitted and we want to
(a) really emit that event to our signal handlers
(b) still be recognized as a real GObject while doing that

Otherwise we fail to link, seeing this:
/usr/bin/ld: gtk3_widget_factory-widget-factory.o: undefined reference
to symbol 'gdk_pixbuf_new_from_resource'
This implements the following part of the EWMH spec:
"The special value _NET_WM_MOVERESIZE_CANCEL also allows clients to cancel the
operation by sending such message if they detect the release themselves
(clients should send it if they get the button release after sending the move
resize message, indicating that the WM did not get a grab in time to get the
release)."
In particular, it fixes the case of clicking widgets that use
gdk_window_begin_[resize|move]_drag*() and the click "sticking", i.e. the
mouse button getting released but the resize or move operation remaining in
effect.
