We currently invalidate the whole tree every time the style state
changes in the tree view. The primary reason for this is to catch
default font changes as that may affect text cell renderers. But
cell renderers could *potentially* also read other style properties
(although that seems weird and unlikely).
We handle this by invalidating only when some state that affects sizes
is changed. This includes all the font properties.
Render a background with gtk_render_background() in draw() instead.
Note that we still use gtk_style_context_set_background() for the header
window.

Currently the GdkWindow used for dragging is created once when
the first drag starts, and the reused identical each time.
Instead, just recreate it for each drag, with the correct size.
Deprecate public API where appropriate and make it no-ops.
Remove all calls to it.
Get rid of the 'transition' css property.
For now, this means spinners don't animate anymore.
Style properties should not be cached, they should be queried live.
Also, this fixes the case where the expander size wasn't set when
constructing the widget which caused expanders to go missing.
This can cause lagging when scrolling as it causes us to repaint
on every scroll event. This wasn't historically a great problem,
but with smooth scrolling we get a lot more events, so this
now creates visible lagging on slower machines.
Don't handle mouse button events greater than 5 so
they can bubble up to be used by the application.
This was causing nautilus list view to not go forward
and backwards when pressing the extra mouse buttons
designated for that.

Since we check for !list->next (and !list->prev for RTL) to set the
GTK_REGION_LAST flag, we have to filter out invisible columns before
looping; if we don't do that we might end up assigning GTK_REGION_LAST
to an invisible column.

In particular gtksettings.h and gtkstylecontext.h needed to be included
in lots of places now.
Also, I order the includes alphabetically in a bunch of headers.
The widget window is usually covered by the bin_window.
Its background color will become relevant when we introduce
kinetic scrolling with overshooting.
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.
Otherwise, we could sometimes fail to update the cursor node when the
right row was deleted.
Also, I'd like to file a formal complaint that this node/tree
differentiation makes writing comparisons too complicated.

Instead, focus nothing and wait until we get focus before doing so. This
restores previous behaviour but still emits proper cursor-changed
events.
Fixes a bunch of bugs in the filechooser which populates the treeview
asynchronously.

No more signal handler is needed, therefore the code can also get rid of
tracking the treemodel. And we use a faster approach for iterating the
changed cellrenderers: We just iterate all columns instead of over all
cell accessibles, as that number is likely quite a bit smaller.
