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.
