f0e31e806f wlr_scene: Fix not updating the scene node when setting a new buffer
If a new buffer is set for a buffer node, we must update the entire
node unconditionally if the buffer size changes, or the buffer is given
a buffer where it was previously NULL.

While we're here, let's avoid calling scene_node_update on just damage
updates. If the caller hasn't given us a damage region we just assume
the whole buffer.

dd9cfd3e2f wlr_scene: Be resilient against overflow conditions
If the area calculations for output overlap overflow a signed int, we
may not consider it to be a primary output. Turn this into an unsigned
type so this happens less frequently.
Additionally, it is possible the overflow would produce 0, we can handle
this by simply changing the comparison to more than or equal.

While we're here, let's assert that we always assign a primary output
if there are any intersecting outputs.

fa7d2cb8d6 wlr_scene: Only consider visible parts of the node when culling background
Originally, I thought that we could safely subtract opaque regions
from the background even if the black rect optimization was kicking in.
This is wrong because a scene node that isn't fully occluded will still
appear in the render list even if its partially under a black rect. We
need to make sure that while culling the background, we only consider
opaque regions that are also visible. This will fix the black rect
optimization with the background.

9bba4284e4 wlr_scene: Cull background
We don't need to worry about the black rect optimization here (that
always assumes that there will be a black background) because the
background is culled based on the render list. That means if a black rect
is removed, the visibility will reach all the way to the bottom forcing
the renderer to clear the area not breaking the assumption.

6d1b8b376d wlr_scene: Only enable black rect optimization if culling is enabled
If culling is not enabled, there is no longer any guarantee that the
elements behind the rect won't be rendered. We must render the black rect
in all circumstances to cover up anything rendered.

This fixes the WLR_SCENE_DISABLE_VISIBILTY option.

ce57485e6a wlr_scene: Calculate output intersections based on node visibility
This has a few benefits one of them crucial for proper operation:
 - The primary output will be based on the largest area that is actually
 visible to the user. Presentation and frame done events are based on
 this state. This is important to do since we cull frame done events.
 If we happen to be in a situation where a surface sits mostly on output
 A and some on output B but is completely obstructed by for instance a
 fullscreen surface on output A we will erroneously send frame_done
 events based on output A. If we base things as they are in reality
 (visibility) the primary output will instead be output B and things will
 work properly.
 - The primary output will be NULL if the surface is completely hidden.
 Due to quirks with wayland, on a surface commit, frame done events are
 required to be sent. Therefore, a new frame will be submitted for rendering
 on the primary output. We can improve adaptive sync on completely hidden
 but enabled surfaces if we null out the primary output in this state.
 - The client will be more likely to choose better metadata to use
 for rendering to an output's optimal rendering characteristics.

14f4cfffba wlr_scene: Don't render non visible parts of textures/rects
We can also get rid of the intersection checks in the rendering functions
because we are guaranteed to already be in the node do to the prior
intersection checking of the node visibility.

c6246272fd wlr_scene: Rework damage handling
Simplify damage handling by using our cached visibility state.
Damaging can happen in one step because since we can use the old visibility
state which represent what portions of the screen the scene node was. This
way we can damage everything in one step after the fact.

3baf2a6bcf scene/layer_shell: Ignore unmapped exclusion zone
Only the exclusion zone for mapped layer shell surfaces should be respected. In
particular, a layer shell surface that was mapped with an exclusion zone but is
now unmapped should not adjust the usable area.

d57d2e0e36 scene/layer_shell_v1.c: fix bug in width/height calculations
...in wlr_scene_layer_surface_v1_configure()

Reproduce bug with waybar by setting `"margin": 5,`
in ~/.config/waybar/config. It will result in the right edge of the panel
extending outside the edge of the output.

The bug can also be reproduced with gtk-layer-demo by anchoring
left/right/top/bottom and setting respective margins

0c2eed533e scene/output-layout: improve ownership logic
This commit ensures that outputs that weren't created by the output
layout helper aren't destroyed on the output layout change.

Consider the following piece of logic:

// struct wlr_output *o1, *o2;
// struct wlr_scene *scene;
// struct wlr_output_layout *layout;
wlr_scene_attach_output_layout(scene, layout);
wlr_output_layout_add_auto(layout, o1);
struct wlr_scene_output *so2 = wlr_scene_output_create(scene, o2);
wlr_output_layout_move(layout, o1, 100, 200);
// so2 is invalid now
