a5949960bc listbase: Compute rubberband region on-demand
Instead of storing the active items as we go, compute the affected items
whenever the rubberband changes and in particular when the rubberband
ends.
That way, the rubberband is guaranteed to select a rectangle even
after scrolling very far.

This is achieved by having a get_items_in_rect() vfunc that selects all
the items in the rubberbanded rectangle and returns them as a bitset.

ec4a489093 listview: Allocate rubberband at end of size_allocate()
Otherwise the rubberband uses the wrong scroll offsets.

c2b0330c56 listbase: Move a common function from the children into GtkListBase
We want to use it for the rubberband later.

2842030e59 gridview: Don't assert on a condition that can happen
We are currently not robust against model changes or
widget invalidations, so we can actually end up in
situations where we run out of items here. Handle
the failure a bit more gracefully, by returning NULL.

This is good enough to make scrolling work okish most
of the time. We still need a proper fix to handle
other situations.

7c2d21892f gridview: Compute right amount of items to skip
We only want to skip the remaining items in the current row, not since
the start of the widget.

f9287941b4 Change css names of list widget
The new names are

GtkListView - listview row
GtkGridView - gridview child
GtkColumView - columnview header
               columnview listview row

Adwaita css has been updated to preserve
existing styles.

Fixes: #2818

14d11ebcab listbase: Use a widget for the rubberband
We no longer need to juggle manual css nodes. Just create
a widget for the rubberband, and update its allocation
as we rubberband.

f611d55f16 Spread single-click-activate api
This makes sense to have in all the views,

e46fa81927 listbase: Take over anchor handling
With that, pretty much all code but allocating the widgets is gone from
the gridview and listview.

33c6b428f7 listbase: Add vfuncs to convert positions to/from coordinates

With that, all keyboard handling has been moved to GtkListBase.

12331e3376 listbase: Move focus moving keybindings here
The focus tracker is not yet moved because that depends on scroll_to()
support and we don't have that yet.
Whoops.
So we use a hack.

0bd16308d6 listbase: Move item manager here
Nothing really changes, because both ListView and GridView still keep
self->item_manager around, but it's set up to point at the base's item
manager.

This way we can slowly move things to GtkListBase that need the item
manager (like trackers).

cc987b31ae Add GtkListBase
This is a base item for GTK's list widgets so they can share some (read:
hopefully a lot of) code.

affd2737d5 gridview: Implement minimum row height
We only allocate a certain amount of widgets - and we don't want to run
out of them. So we make all widgets high enough for this to never
happen.

ea93e18081 gridview: Actually do something
Implement measuring and allocating items - which makes the items appear
when drawing and allows interacting with the items.

However, the gridview still does not allow any user interaction
(including scrolling).
