Clicking on steppers does different things depending on which
button you use. We used to scroll to the end on secondary click
and use high-speed autoscrolling on middle-click. Switch these
two around, since the scroll-to-end functionality is less likely
to be useful, and the seconary button makes the autoscrolling
more easily available.
Even if we only ever hit the code with a singleton selection,
calling gtk_tree_selection_get_selected is not ok if the tree
selection mode allows multi-selection. Replace all calls to
gtk_tree_selection_get_selected in the file chooser code with
callback loops iterating over the selection. This problem
was introduced with the recently added rename and delete
menuitems.
Whenever we change directories, we unset the model, and then
we set a new model. This causes several emissions of
GtkTreeSelection::changed, for each of which we do a bunch
of work to update the path bar, the location entry, etc.
We can savely ignore some of these signals, and do less work.
There is no need to animate things when we are just setting up
the startup mode, so disable transitions in the revealer and
the stack. Pointed out by Carlos Soriano
There was some code that lead to the places sidebar loosing track
of the row being dragged if a motion event came in between letting
go of the button and the drag snap-back animation ending. This would
cause us to not show the row again, giving the appearance that it
was 'lost'.

The current widget lookup code bails out on insensitive widgets, there's
however legit cases where we want DnD handled by a parent of the insensitive
widget, so just keep going upwards in that case.
We also use now the widget state flags, because get_sensitive() doesn't
propagate across hierarchies, so we could conceivably find a drop site
inside an insensitive widget.

This behavior has been made optional on add_popover() time, text handles
will keep being able to overflow the window, in order to allow text
selection on views too close to the window edge.
Regular GtkPopovers are reinstaurated to the previous size positioning
logic though, that is, limited by the visible area of the window.
For now assume that if those flags change for a node, they also changed
for all sibling nodes. This is not strictly true but simplifies
invalidation.
The reason it simplifies invalidation is that when removing or adding a
node, we can just invalidate the first node (for NTH_LAST_CHILD) and the
new node (for NTH_CHILD) and all the other nodes will be invalidated
automatically.
Instead of GTK_CSS_CHANGE_POSITION we now have 4 values:
GTK_CSS_CHANGE_FIRST_CHILD, GTK_CSS_CHANGE_LAST_CHILD,
GTK_CSS_CHANGE_NTH_CHILD and GTK_CSS_CHANGE_NTH_LAST_CHILD
Nobody is using them directly yet.
