We used to special handle gradient, but we want to be able to store
other sources (that will eventually resolve to cairo patterns).
For instance, this is needed to handle win32 theme part sources.
In gtk_tree_view_state_flags_changed() we were setting the background on
the bin_window without the necessary "view" style class, making the
treeview render with the wrong color in some circumstances (such as when
adding an empty treeview in a window, as spotted by Brian Smith).
We used to explicitly map and unmap the child GtkRecentChooserWidget when
mapping and unmapping the dialog, respectively. Now that GtkContainer actually
unmaps child widgets (instead of avoiding that), we can assume that the
child GtkRecentChooserWidget will be unmapped when we want it to be.
This fixes a warning from gtk_widget_verify_invariants(), as we were mapping
our child widget before calling our parent class' ::map() handler. Bug #659257.
Try to find keycodes for keysyms at level-0 in the keymap, but don't
fail to parse if we can find those in level-1. This fixes the
parsing of numerical keys on the keypad, which require a shift level
through Num-Lock.

This way, the a11y code knows if a column was reordered, added or
removed and can do the right things instead of trying to guess and
getting it wrong.
Also, this patch finalizes the changes so that only visible columns
exist to the accessibility interface.
In fact, invent our own function get_n_columns() which actually only
counts the visible functions, because that's the only ones we care
about.
The places where it's not used yet will be changed in the coming
patches.
.. 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.
This function returns the accessible if it already exists. This way we
can call functions on the accessible from the widget itself instead of
having to rely on signals.
Instead of requiring a special functio to be called before just removing
from the hash table. This simplifies code a lot that used to remove from
the hash table.
- Name it properly
- Make it just a set of cell_infos
Currently it's using direct hash, but as long as we don't actually
lookup stuff from it, who cares...
