It turns out that i3 does not have a `class` key in the json description
of a view, but provides it through `window_properties.class`. Since
`window_properties` has been added by 8fc9328, we can remove `class`
altogether.

In i3, when a child of a tabbed or stacked container has no siblings,
its border settings are respected.
This patch achieves the same effect by rendering a lone tabbed/stacked
child as if it's a linear container. This makes the border settings be
respected.
Over in view_autoconfigure, we compensate for this by only adjusting
`y_offset` if there's multiple children.
The code being changed is responsible for updating the focus stack when
a container is destroyed in a different part of the tree to where the
real focus is. It's attempting to set focus_inactive to a sibling (or
parent if no siblings) of the container that is being destroyed, then
put our real focus back on the end of the focus stack.
The problem occurs when the container being destroyed is in a different
workspace. For example:
* Have a focused view on workspace 1
* Have workspace 2 not visible with a single view that is unmapping
* The first call to seat_set_raw_focus sets focus to workspace 2 because
it's the parent
* Prior to this patch, the second call to seat_set_raw_focus would set
focus to the view on workspace 1
* Later, when using output_get_active_workspace, this function would
return workspace 2 because it's the first workspace it finds in the
focus stack.
To fix this, workspace 1 must be placed on the focus stack between
workspace 2 and the focused view. That's what this patch does.
Lastly, it also uses seat_get_focus_inactive to choose the focus. This
fixes a crash when a view unmaps while a non-container is focused (eg.
swaylock), because focus is NULL.
When a floating container is tiled (e.g.: 'floating toggle' or
'floating disable'), it should be placed after/below the inactive
focused container from the tiling layout.
This approaches cursor rebasing from a different angle. Rather than
littering the codebase with cursor_rebase calls and using transaction
callbacks, this just runs cursor_rebase after applying every transaction
- but only if there's outputs connected, because otherwise it causes a
crash during shutdown.
There is one known case where we still need to call cursor_rebase
directly, and that's when running `seat seat0 cursor move ...`. This
command doesn't set anything as dirty so no transaction occurs.
This fixes a regression introduced by
662466e8db. When adding a container to the
scratchpad, setting container->scratchpad = true before
container_set_floating made container_set_floating believe that the
container was already floating. This fixes it by setting the property
afterwards instead.
For example, create layout H[view T[view view view]], focus the view in
the hsplit and scroll the mouse wheel over the tab title bars. Prior to
this patch, focus would be given to a descendant of the tabbed
container. This patch keeps the focus on the hsplit view.
This also renames some of the variables used in this part of the code to
make it be easier to follow.
I originally put the rebase at the end of view_map, but at this point
the view is still at its native size and will ignore the motion event if
it falls outside of its native size. The only way to do this properly is
to rebase the cursor later - either after sending the configure, after
the view commits with the new size, or after applying the transaction. I
chose to do it after applying the transaction for simplicity.
I then attempted to just call cursor_rebase after applying every
transaction, but this causes crashes when exiting sway (and possibly
other places) because cursor_rebase assumes the tree is in a valid
state.
So my chosen solution introduces transaction_commit_dirty_with_callback
which allows handle_map to register a callback which will run when the
transaction is applied.
Prior to this patch, creating a tabbed container with two views,
switching tab and then scrolling without motion would cause the scroll
events to be sent to the old focus. To fix this, rebasing the cursor is
needed after changing focus.
