.. as a replacement for _gtk_rbtree_node_find_parity(). Instead of 1 or
0, the function now returns the index of node in the complete tree
(counting from the root). And this is of course identical to the row
number.
Track the RBNode/RBTree instead of keeping a TreeRowReference. This is a
whole lot faster and less error-prone.
Also, notify the accessible of removal of rows before actually removing
them, so we have a chance to clean up.
The default (out) transfer mode is "full", but the passed "model" pointer gets
set to gtk_tree_view_get_model() which is "transfer none". This caused Python
programs to free the model after calling this, causing crashes.
in gtkimcontextsimple and gtktreeview, which are the easy places,

which are SHIFT and MOD2 on the Mac, and SHIFT and CONTROL otherwise.
Use the new define all over the place and rename variables and
members to not say "shift" or "control".
This commit introduces a new setting, gtk-visible-focus, backed
by the Gtk/VisibleFocus X setting. Its three values control how
focus rectangles are displayed.
'always' is equivalent to the traditional GTK+ behaviour of always
rendering focus rectangles.
'never' does what it says, and is intended for keyboardless
situations, e.g. tablets.
'automatic' hides focus rectangles initially, until the user
interacts with the keyboard, at which point focus rectangles
become visible.

Now that we are not allocating treeview column buttons anymore
with invisible headers, we can't rely on their allocations for
other things like cell area computations anymore. Use x-offset
and width of the column directly, instead.
Include the child widget path in the returned path now. This allows
customizing the path of the current widgets - like adding flags to child
widgets (and maybe siblings in the future).
Patches by Benjamin Otte.
The "invalidate last column" hack is removed. It is now of no use since
the entire widget will be redrawn when a single column changes.
We have to redraw if we are below a couple of rows that changed height
in do_validate_rows(). This will still require a redraw for a large
amount of cases, can we do better? You would expect that a redraw of
the tree view is not required when the dy changes with the same delta
as the delta of the height accrued when validating the nodes. This
further optimization will likely require changes to the top_row/dy
synchronization code.
It turns out that the gtk_grab_remove() can trigger a do_prelight()
call, which may end up changing prelight_node, and then the state
gets messed up. Moving the grab removal until after we're done with
button_pressed_node and prlight_node makes expanders work reliably.
One thing that is still not right is that the expander doesn't get
prelight again after the animation is done, if you manage to release
without any additional motion events.

Expander animation has been replaced by implicit animations
from the style context.
Column headers are also properly themed, GtkContainer::get_path_for_child()
is implemented and the treeview resets column buttons style on columns
being reordered.
The default CSS has changed to theme treeviews sensibly.
