Allow -1 for the hotspot coordinates in gdk_cursor_new_from_pixbuf,
if the pixbuf contains the x_hot/y_hot options with appropriate values.
Bug #632140.
We build the examples that are included in the 'getting started'
chapter of the docs to prevent them from bitrotting. Also
remove the awk scripts used to extract the old examples from
the tutorial, since the tutorial is gone. I'm still leaving
the examples themeselves in place, for possible inclusion in
'getting started' later on.
We add a "Getting started" chapter that will grow into a
(hopefully) non-outdated, maintained tutorial. For now, it
includes two minimal examples by xincluding them.
We cannot use the GtkButton::clicked signal to override the default
behavior of GtkLinkButton (i.e. call gtk_show_uri()), because
GtkButton::clicked is registered as a RUN_FIRST signal, which obviously
prevents any other signal handler connected to it to stop the
propagation before the class handler has a chance to run.
For this reason we can add a GtkLinkButton::activate-link signal, which
will be emitted by the default GtkButton::clicked signal handler; the
::activate-link signal has a boolean return value, which allows simpler
code for stopping the propagation to the next signal handler.

Removed portion of scrolled-window that observes user-set
size request data (aux_info->width/height) on the child directly
in order to derive it's minimum possible size... if the scrolled
window has (auto/always) scrollbars in a said orientation; only
request enough space for the scrollbars (bug 631976).
The idea is that it is way more common to want to manipulate the
actual list, rather than the headers. Once you Tab into the treeview
(and the list part gets the focus), you can use Shift-Tab to focus
the headers.
This means that some hysteresis is added to the focus chain, but
it makes the treeview a lot more convenient to focus with the keyboard.

Because validate_visible_area() can modify the window size (and thus
the underlying surface), it should not be called from within the draw
method. Given that the presize handler is run with a higher priority
than redraw, and the presize handler will validate the visible area,
there should not be cases wherein the draw method is called and
validate_visible_area() has not been run yet.
However, one such a case was gdk_window_process_updates(), which would
trigger the draw method at some point. We now work around this
by factoring this in a new gtk_tree_view_bin_process_updates() function
that will run the presize handler first if needed.
Note: for other platforms, it might still be the case that the draw
method is called and validate_visible_area() has not been run yet.
(For example the Mac backend calls gdk_window_process_updates() from
the drawRect method, and the redraw-in-idle handling thus works
differently). This does not seem to be a problem now, if
it will be in the future we need to take care of that then.
This test is constructed in such a way that it breaks when you
(currently!) do not trigger a size-request from validate_visible_area.
Especially row expansion appears to have a need for this currently.
Add signal GdkWindow::create-surface which allows to use any
surface type as storage for offscreen windows.
Test the new signal in tests/gdkoffscreenbox.c
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 expand a tab if either tab-expand is set, or the generic widget
expand property in the correct direction is set. And we do not
propagate expand flags from tab labels to the notebook, only
the expand flags from the pages.
We expand a child when it either has the table-specific expand flag
or the generic expand property set. Override compute_expand so that
it also takes the table-specific expand flags of children into
account.

This consists of:
* expand a child if either child->expand || gtk_widget_get_expand(child)
* override compute_expand so that child->expand will cause us to
return TRUE for gtk_widget_get_expand()

There are two colored boxes with toggle buttons nested
inside several GtkBox. Toggling these to expand mode
should automatically propagate expansion up through
the several GtkBox such that resizing the window
results in resizing the colored boxes.

GtkWidget now has flags for horizontal and vertical expand, and
a compute_expand() method. compute_expand() is used by containers
to set a default expand flag. (If a widget has expand set explicitly,
it always overrides the results of compute_expand.)
GtkContainer has a default implementation of compute_expand which
simply walks over all child widgets and sets expand=TRUE
if any child is expanding.
The overall effect is that you only have to set expand on
leaf nodes in the widget tree, while previously you had to
set expand all the way up the tree as you packed every
container. Also, now containers need not have their own child
properties for expand.
For old containers which do have "expand" child properties,
they should override compute_expand and include the child
properties in whether the container is expand=TRUE.
Also, the old container should use
"child_prop_expand || gtk_widget_compute_expand()" everywhere
it previously used simply "child_prop_expand"

Safe space in the private struct, always set the cursor when we
update visibility, since the cursor depends on resizability conditions
too. And don't set the shape needlessly.
