Since setting a clip is mandatory for almost all widgets, we can as well
change the size-allocate signature to include a out_clip parameter, just
like GtkCssGadget did. And since we now always propagate baselines, we
might as well pass that one on to size-allocate.
This way we can also make sure to transform the clip returned from
size-allocate to parent-coordinates, i.e. the same coordinate space
priv->allocation is in.
Instead of hopping through 7 different functions to do that, just
remove all rows directly. This also mean we'll only remove rows and not
other children that've been added like placeholders.
Drop the in_widget flag since motion events the listbox receives are
always inside the listbox. Also drop the manual coordinate translation
code using GdkWindows.
We now rely on toplevels receiving and forwarding all the events
the windowing should be able to handle. Event masks are no longer a
way to determine whether an event is deliverable ot a widget.
Events will always be delivered in the three captured/target/bubbled
phases, widgets can now just attach GtkEventControllers and let those
handle the events.
Turns out that the destination is the last parameter, not the first one.
This fixes the flickering in the first page of the widget-factory when
using the expander on page 2.
GtkListBox is not a windowed widget anymore so we can't use
gtk_widget_get_window. Just directly access priv->view_window instead to
get the right window.
These complicate a lot of GdkWindow internals to implement features
that not a lot of apps use, and will be better achieved using gsk.
So, we just drop it all.
Add a new ::measure vfunc similar to GtkCssGadget's that widget
implementations have to override instead of the old get_preferred_width,
get_preferred_height, get_preferred_width_for_height,
get_preferred_height_for_width and
get_preferred_height_and_baseline_for_width.
The code always assumed that getting a row at a certain 'y' was
possible but if the list box has more empty space than rows then a
valid row may not be retrieved.

do_sort will crash if sort_func is not defined. Instead of adding a check
there in the hot path, just check for sort_func before invalidating the
sort of the underlying GSequence.
When the current cursor_row is taller than the page_size we get from the
GtkAdjustment, the previous code would not actually cause any scrolling,
so make sure we just take the row after or before the cursor_row in that
case.

Always have Since: annotations at the very bottom, use the correct
ClassName::signal-name/ClassName:property-name syntax, fix a few typos
in type names, wrong function names, non-existing type names, etc.
