  2. Remove API that relies on our rendering 

    This is a preparation for switching to the wlroots scene-graph. There is
no replacement planned for output:redraw() because it will no longer be
necessary (as far as i can tell), while scene-compatible replacements
for the view pre_render/post_render events are planned.

  3. Introduce kiwmi_strata 

    With the migration to wlr_scene, some objects (desktop, output etc)
will no longer have any reason to care about individual shells and
similar; handling each one on its own would introduce code that is,
from their perspective, over-complicated.

Strata (sg. stratum; this name was chosen to avoid confusion with the
over-used 'layer') represent logical layers of surfaces on the desktop,
such as every layer shell layer, one for xdg shell, another for popups.

  4. Keep an up-to-date wlr scene-graph 

    At the moment it isn't used at all and a lot of data is duplicated. This
is a temporary state introduced for nicer diff separation into several
commits.

  5. Render using wlr_scene 

    Apart from removing a lot of code, this commit also introduces (thanks
to wlr_scene) fine-grained damage tracking.

The lack of our own rendering code will only be an issue if the need for
custom effects (such as blur) arises; however, that's very unlikely and
it would probably require a lot of changes anyway.

  6. Prefer wlr_scene as the source of truth 

    Use it for getting the surface under cursor, position of surfaces, etc.
