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.
read advances the file description offset, and requires the client to
ensure that it is reset appropriately before the next gamma ramp
submission. As there is no event to indicate that wlroots finished
processing the new gamma ramp, this can result in a race between the
client seeking in the file and wlroots reading its content.
Use pread with a fixed offset instead.

According to the protocol text, the popup will be immediately dismissed
when the grab is rejected. Because the grab can't be executed with a
destroyed seat, the popup is dismissed when one is provided.
Many issues here:
- wlr_output_cursor_set_buffer() takes a buffer already scaled for
the output, not a buffer with scale=1.
- wlr_output_cursor.{width,height,hotspot_x,hotspot_y} are in output
buffer coordinates.
- render_cursor_buffer() had hardcoded no-ops for scale and
transform, instead of using the cursor surface's.
Fixes: b64e7e88bf ("output: add output_cursor_set_texture()")
A client might update the cursor with the same wl_surface as
before, but with a different hotspot. Don't ignore such updates.
Fixes: 9c9e3f6263 ("cursor: ignore wlr_cursor_set_surface() with same surface")
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.
If a modeset contains a render format change, use that instead of
the current one stored in wlr_output.render_format.
This fixes render_bit_depth configuration not being applied without
a second modeset in Sway.
Some formats like sub-sampled YCbCr use a block of bytes to
store the color values for more than one pixel. Update our format
table to be able to handle such formats.
According to the spec the compositor should send scanout modifiers in
their respective device tranches, and all other texture modifiers
in the main tranche. Currently wlroots expects all modifiers to be
present in the last (i.e. "fallback") tranche, this removes that assumption
in the feedback compilation stage so that scanout modifiers for secondary
device can be advertised.
"The full-screen feedback parameters have two tranches: one with the
format/modifier pairs supported by the KMS plane, with the scanout flag
set in the tranche_flags event and with tranche_target_device set to the
KMS scan-out device; the other with the rest of the format/modifier
pairs (supported for texturing, but not for scan-out), without the
scanout flag set in the tranche_flags event, an"
The Wayland, X11 and headless backends don't really care about the
cursor size. We were picking a size identical to the texture size
in that case. This is incorrect for LoDPI cursor textures on HiDPI
outputs: in that case, we need to scale up the cursor texture.
Fixes the cursor being chopped off under the Wayland backend with
scale > 1.
Add a src_box state field. Use the SRC_* KMS props in the DRM
backend, reject the layers in the Wayland backend (for now, we can
support it later via viewporter).
This makes seat_client resources inert when seats and/or input devices are
destroyed, rather than destroying the resources.
When the client calls e.g. wl_keyboard_release(), it's not expecting the
keyboard global to be already destroyed, so this results in an error such
as this:
wl_display@1: error 0: invalid object 22
wlr_output is not well-suited to checking whether direct scan-out
is happening or not. Compositors may want to use their own external
swapchains, for instance.
Additionally, ab7eabac84 ("output: leverage
wlr_output_configure_primary_swapchain()") makes it so
output_basic_test() is called before the output swapchain is
initialized, resulting in false positives.

This allows callers to set a destination size different from the
buffer size to scale them.
The DRM backend supports this. The Wayland backend doesn't yet
(we'd need to wire up viewporter).
- Simplifies the backends
- Avoids having two ways to do the same thing: previously one could
disable a layer by either omitting it from wlr_output_state.layers,
or by passing a NULL buffer
- We can change our mind in the future: we can allow users to omit
some layers and define a meaning without breaking the API.

When a new client comes in and tries to create a
zwlr_gamma_control_v1 object for an output which already has one,
we were destroying the old object and early-returning. The early
return causes the new object to not be set up properly: it's not
inserted in the list and doesn't get the gamma_size event.
Fix this by destroying the new object, and leave the old object
intact, which is what was the intent I think.
Closes: https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/3605
Replace our current logic to setup the primary swapchain with
wlr_output_configure_primary_swapchain().
- Removes some code, reducing duplication
- Stop overwriting wlr_output.swapchain with a yet-to-be-tested
swapchain: remove the error_destroy_swapchain label.
We've had this struct for a while. It'd be useful for compositors
if they want to manage the swap chains themselves instead of being
forced to use wlr_output's. Some compositors might also want to use
a swapchain without an output.
