57a0313779 wlr_scene: Don't recompute node location during rendering
We already compute it during the render list creation, we should cache
it and re-use the value.

48f2a7a3a1 wlr_scene: Simplify direct scanout handling
By adding a sent_feedback bool into the list entry that we can mutate
we no longer need to maintain this `sent_direct_scanout_feedback` variable.

sent_feedback will also be useful for output layers.

ea3c6fde3a wlr_scene: Add opaque region blend mode optimization

be05097968 output: add wlr_output_state_init()
This changes the semantics of wlr_output_state. Instead of having
fields with uninitialized memory when missing from the committed
bitflag, all fields are always initialized (and maybe NULL/empty),
just like we do in wlr_surface_state. This reduces the chances of
footguns when reading a field, and removes the need to check for
the committed bitfield everywhere.

A new wlr_output_state_init() function takes care of initializing
the Pixman region.

9e8947e4d5 add render timer API
Based on five calls:
wlr_render_timer_create - creates a timer which can be reused across
  frames on the same renderer
wlr_renderer_begin_buffer_pass - now takes a timer so that backends can
  record when the rendering starts and finishes
wlr_render_timer_get_time - should be called as late as possible so that
  queries can make their way back from the GPU
wlr_render_timer_destroy - self-explanatory

The timer is exposed as an opaque `struct wlr_render_timer` so that
backends can store whatever they want in there.

88f80c4a7c wlr_scene: Make scene_tree_from_node public
This is to allow for compositors that want to be more implicit about
how their scene is organized. Such a compositor may want to walk up
at a certain scene node to find something such as a surface to focus on.

8e80432a72 scene/layer_shell_v1.c: set exclusive zone correctly
...when only one edge is anchored.

The layer-shell protocol specifies that a positive exclusive-zone value is
'meaningful' if the surface is anchored to either:

1. one edge
2. one edge and both perpendicular edges.

For example, if you wish to position a layer-shell client along the top
edge and make it exclusive, you should be able to either set anchor=TOP or
anchor=TOP|LEFT|RIGHT. It appears that many panels/bars use the latter
approach (anchor to an edge and also both perpendicular edges) which is
probably why this has not been reported previously.

This patch adds support for the first case and thereby makes exclusive
zone behaviour consistent with the protocol and also with sway's extant
layer-shell implementation.

35a0d9c85d scene: set output damage during direct scan-out
This allows the backend to have access to the frame damage, as
reported by the scanned-out client. Some KMS drivers can make use
of it (e.g. for PSR, or optimized USB transfers in the GUD driver),
and the Wayland/X11 backends forward it to the parent compositor.

258bf9be1e compositor: drop wlr_surface.{sx,sy}
The concept of a persistent accumulated surface offset is wrong
from a protocol point-of-view. wl_surface.offset is tied to a
commit, its interpretation depends on the surface role.

For example, with the following sequence:

    wl_surface@1.offset(1, 1)
    wl_surface@1.commit()
    wl_pointer@2.set_cursor(wl_surface@1, 42, 42)

The final cursor hotspot is (42, 42): the commit which happened
before the set_cursor request has no impact on the hotspot
computation.

The wlr_output_cursor logic already uses wlr_surface.current.{dx,dy}.
wlr_scene's drag icon doesn't, update it accordingly.
