Commit d64467b334 changed the
code to send GDK_SCROLL_SMOOTH with deltas instead of
GDK_SCROLL_(UP|DOWN|LEFT|RIGHT). Change it again, to send
both the GDK_SCROLL_SMOOTH and the GDK_SCROLL_(UP|DOWN|LEFT|RIGHT)
event separately (with the discrete event marked as emulated),
as this is what other backends (such as wayland) do.
Up until now when allocating the child it only used the natural size
while the measuring also used the minimum size, resulting in a clipped
child when animating if the child had different minimum size and
natural size. This was an obvious case when using labels that had
ellipsization.
This commit gives full allocation to the child by inverting the size
the revealer reduces from its animation progress.

The complexity with model items vs row items is really confusing. Add to
that treelistmodel position vs child model position vs parent position,
and you're so confused, even the best naming can't help.
And once you're there, consider passthrough vs non-passthrough...
When passthrough is enabled, it should return the GType
of the child GListModels; when disabled, it should be
GTK_TYPE_TREE_LIST_ROW.
The conditions are inverted however, causing a few
warnings to trigger.
Fix that by returning the correct GType.
Most of the code creating the two types of dialogs (open file,
choose folder) is the same. This refactors the common code into a
helper method. This also makes it easier to add other chooser types
for this test (e.g. save file).
This is way more complicated than it should be, because it requires
manually limiting the number of open file enumerators.
On the other hand, it exhaustively tests the items-changed emission of
all involved listmodels because those signals come in pretty much
randomly.
It's also 50% slower than the sync version, with the caeat that the sync
version only shows the UI after it's done loading, while this version
shows it right away.
This model just takes an object and a property name and recursively
looks it up. In particular, I want it for:
widget, widget.parent, widget.parent.parent, ...
The code gets rid of the GtkTreeView and replaces it with a GtkListBox.
Most of the logic is now done via GListModel subclasses.
A big change is that this new list is now tracking updates itself and
doesn't need to be manually updated. All code that used to cause rescans
or add forgotten objects to the tree has been removed.
If objects are missing from the object tree, the logic for tracking them
needs to be added.
This patch does multiple things:
1. Add a custom persistent per-row object.
2. Move all per-row API to that object. This means notifications are now
possible.
3. Add a "passthrough" construct-only property to the TreeListModel that
influences if the model returns these new object or passes through
the ones from the model.
This greatly simplifies the code needed to be written for widgetry,
because one can just connect the per-row object to the expanders that
expand and collapse rows.
As an added power feature, these objects can also be passed through
further models (like filter models).
It also adds kind of a hack to Adwaita to make the test look neat.
