Simon Ser 697a1cd0f5 output: add wlr_output_get_primary_formats
This allows compositors to get primary formats without manually
calling wlr_output_impl.get_primary_formats.

For example, the Sway patch for linux-dmabuf feedback [1] needs
this.

Simon Ser e93435016e output: fix typo in wlr_output_impl.get_primary_formats docs

Simon Ser 2540de494e output: don't leave dangling cursor_front_buffer
Sometimes we were calling wlr_output_impl.set_cursor with a NULL
buffer, but we weren't clearing wlr_output.cursor_front_buffer.
Avoid leaving a dangling buffer behind.

Introduce a helper function output_set_hardware_cursor which calls
wlr_output_impl.set_cursor and keeps cursor_front_buffer in sync.

Rouven Czerwinski 6bfb930aa7 linux-dmabuf-v1: fix implicit check
The implicit check to filter out LINEAR for dmabuf checked for INVALID
twice instead of checking for INVALID & LINEAR. Fix this.

Simon Ser fbaefd90fc backend/drm: poison buffers which cannot be scanned out
Rather than repeatedly trying to import DMA-BUFs which cannot be
scanned out, mark the failed ones with a special "poison" marker.

Rouven Czerwinski d37eb5c2ea linux-dmabuf-v1: filter out LINEAR if implicit
If only INVALID and LINEAR are valid modifiers, we need to filter out
LINEAR since Xwayland won't be able to allocate a BO with the explicit
linear modifier on hardware that does not support explicit modifiers.
The addition of LINEAR is an internal implementation detail which
simplifies the wlroots architecture for now.

Evntually Xwayland should be fixed to filter out modifiers that are not
supported by the GBM implementation, see [1]. This could be done by
querying EGL for the supported modifiers.

Simon Ser 585a908a01 scene: add wlr_scene_xdg_surface_create
This allows compositors to easily add an xdg_surface to the

and decide their final position.

Compositors can handle new popups with the wlr_xdg_shell.new_surface
event, get the parent scene-graph node via wlr_xdg_popup.parent.data,
create a new scene-graph node via wlr_scene_xdg_surface_tree_create,
and unconstraint the popup if they want to.

The headless backend no longer needs a parent renderer: it no longer

need to return its DRM FD in wlr_backend_impl.get_drm_fd. Drop this
function altogether since it now behaves exactly like
wlr_headless_backend_create.

Simon Ser f29abe4c77 backend/headless: stop picking a DRM FD
Sometimes the headless backend is used standalone with the Pixman
renderer, sometimes it's used together with another backend which
has already picked a DRM FD. In both of these cases it doesn't make
sense to pick a DRM FD.

Broadly speaking the headless backend doesn't really care which DRM
device is used for the buffers it receives. So it doesn't really
make sense to tie it to a particular DRM device.

Let the backend users (e.g. wlr_renderer_autocreate) open an arbitrary
DRM FD as needed instead.

The above output was based on just shoving it in ShaderPlayground -- I was not able to use pipeline feedback as I was unable to get RenderDoc working due to the EXT_physical_device_drm requirement.

I additionally considered using >> 1 instead of * 0.5, but AMD has dedicated modifiers to merge a * 0.5, * 2.0, etc in a single instruction. (Albeit, not taken advantage of in the code above, but might with ACO)

Manuel Stoeckl d0bb7df630 output: remove XRGB8888 cursor fallback format
All graphics drivers supporting cursor planes support ARGB8888,
the default cursor format, so this fallback is almost certainly
unused.

Essentially all cursor themes use alpha transparency to make it
clearer where relative to the screen content the cursor hotspot is.
It is better to fall back to a slightly slower software cursor than
it is to fall back to the opaque square that is a hardware cursor
without an alpha channel.

Manuel Stoeckl e879d566bb output: Add function to set preferred render format
This change introduces new double buffered state to the wlr_output,
corresponding to the buffer format to render to.

The format being rendered to does not control the bit depth of colors
being sent to the display; it does generally determine the format with
which screenshot data is provided. The DRM backend _may_ sent higher
bit depths if the render format depth is increased, but hardware and
other limitations may apply.

Manuel Stoeckl 3d7d6ec06f output: use XRGB8888 format instead of ARGB8888
Most (and possibly all) compositors using wlroots only ever render
fully opaque content. To provide better performance, this change
switches the default format used by wlr_output buffers from
ARGB8888 to the opaque XRGB8888.

Compositors like mutter, kwin, and weston already default to
XRGB8888, so this change is unlikely to expose any new bugs in
underlying drivers and hardware.

This does not affect the hardware cursor's buffer format, which is
still ARGB8888 by default.

As part of this change, the X11 backend (which does not support
changing format at runtime) now picks a true color, 24 bit depth
visual (i.e. XRGB8888) instead of a 32 bit depth (ARGB8888) one.

Simon Ser 33eba9080c output: fix renderer buffer cap sanity check in wlr_output_init_render
The backend and renderer don't directly interact together, so there's
no point in checking that their buffer caps intersect. What we want to
check is that:

- The backend and allocator buffer caps are compatible, because the
  backend consumes buffers to display them.
- The renderer and allocator buffer caps are compatible, because the
  renderer imports buffers to sample them or render to them.

For instance, when running with the DRM backend and the Pixman renderer,
the (backend & renderer) check will fail because backend = DMABUF and
renderer = DATA_PTR.
