Based on a patch by Matthias, add an "active-id" property for
GtkComboBox and add some convenience API for GtkComboBoxText.
Also, add a test case to gtk-demo.
It is really bad code, mostly unused and no one stepped up to fix it.
Note that Gtk developers do not object to a ruler widget in priciple,
just to the current implementation. If someone wants to propose a sane
version, please don't hesitate.

It is just too annoying to have to implement these properties in
every scrollable. Instead, we now have ::min-content-height/width
in GtkScrolledWindow.
We also add GtkScrollablePolicy to determine how to size the
scrollable content.
The GtkScrollable interface provides "hadjustment" and "vadjustment"
properties that are used by GtkScrolledWindow. It replaces
the ::set_scroll_adjustment signal. The scrollable interface
also has ::min-display-width/height properties that can be
used to control the minimally visible part inside a scrolled window.
Use input-only windows for capturing input, and just draw onto
the parent window. This allows themes to make entries with rounded
corners. Patch by Boram Park.

GtkComboBox now sports a construct-only "has-entry" property which
decides if it uses a GtkEntry to allow additional user input. Also
it has a new "entry-text-column" to fetch strings for the entry
from the model.
This patch deprecates the GtkComboBoxEntry and updates the rest of GTK+
to use the new semantics on GtkComboBox instead.
GtkComboBoxEntry will be removed altogether before GTK+ 3, in a
later commit.
We remove the resize grip from GtkStatusbar, but keep the code
that makes the content avoid the grip, and adapt it to GtkWindow
grips.
The gtk_status_bar_set/get_has_resize_grip() functions and related
properties are removed.
Allow any window to display a resize grip, in the south-east or
south-west corner, depending on text direction. This is implemented
as a shaped window that gets overlayed on top of whatever content
is there. We add api that allows widgets to avoid the resize grip,
if desired.
The ::has-resize-grip property controls if a window may display
a resize grip. It will only be displayed if the window is resizable
and not maximized.
The size and visual appearance of the resize grip is under theme
control, using the resize-grip-width/height style properties and
the paint_resize_grip style function.
It turns out that the previous handling of just providing a way to set
visuals just on toplevels was not sufficient. In particular it
complicated the various implementations of the tray icon specification.
This patch reintroduces gtk_widget_set_visual() which behaves very
similar to GTK2's gtk_widget_set_colormap().
A future commit will remove the gtk_window_set_visual() function.
The function reverses the transform that GTK does before emitting a draw
event. So we can use it in "old" widgets to revert the coordinate system
properly.
