The mapping is shared between all users of the stage span, so it should
always map the whole thing and apply the allocation offset to the mapped
pointer.
The use of stage spans for 3dluts was missed when the new cached
mappings were introduced, meaning that it would try to map and unmap
memory that might already have a cached mapping.
Vulkan does not support mapping memory multiple times, so make sure the
3dlut code also uses the cached mapping to avoid segfaults after unmap.
Limiting the position to (x + width - 1, y + height - 1) created a 1px
"dead zone" at monitor edges, noticeable with high-resolution mice with
motion deltas of <1px.
See: https://github.com/swaywm/sway/issues/8110
Using (x + width - 1/65536, y + height - 1/65536) instead should make
the "dead zone" small enough to be unobservable, while the value 1/65536
is still large enough to avoid rounding to zero (due to loss of
significant digits) in simple floating-point calculations.
This does expose a client-side bug in Qt layer-shell applications,
noticeable in right/bottom panels which do not accept positions beyond
(x + width - 1, x + height - 1) as valid - thus driving the cursor
to the bottom/right of the screen to click on the panel does not work.
I don't have a good workaround for this, and probably it needs to be
fixed in Qt itself.

This will let compositors know if changing adaptive_sync state has any
chance of working. When false, then the current state is the only
supported state, including if adaptive_sync is currently enabled as is
the case for Wayland and X11 backends.
When true, changing state might succeed, but no guarantee is made. It
just indicates that the backend does not already know it to be
impossible.
We don't need to process all events, only those that come from the host
compositor. This also avoids running user event handlers while in the
middle of committing an output.

Some DRM devices are not KMS-capable. DRM card nodes (also
known as DRM primary nodes) are created for render-only devices
as well. Let's just use "KMS" everywhere instead of "DRM" and
"DRM card".
This commit fixes the following interaction:
1) The host compositor sends a configure sequence for an output.
2) Before handling it, the guest compositor disables and immediately
re-enables the output.
3) The guest compositor tries to ack the configure event from step 1
which isn't relevant anymore after unmapping and re-initialization.
Instead, ignore all configure events after unmapping until we're sure
the host compositor has processed the unmapping.

https://gitlab.freedesktop.org/wayland/wayland-protocols/-/issues/108.
- Reset all variables representing an initialized xdg_toplevel's state
on unmap.
- Send an initial commit only when an output is about to be enabled.
- If an output isn't configured yet, don't commit a buffer.
If the guest compositor disabled an output and then immediately
committed another state, we would perform a commit with a null buffer,
which is against the protocol, as the host compositor expects an
initial commit with no buffer at all.
This makes it possible for GCC to print more warnings. For instance,
the docs for -Wmaybe-uninitialized state [1]:
> These warnings are only possible in optimizing compilation, because
> otherwise GCC does not keep track of the state of variables.
Other warning options have similar requirements as well.

It's cumbersome for compositors to guard every
wlr_color_transform_ref() or wlr_color_transform_unref() call
behind a #if WLR_HAS_COLOR_MANAGEMENT. Moreover, none of the LCMS2
types are used in our public API.
Instead, always install the color.h header, and add a stub for
wlr_color_transform_init_linear_to_icc().
