447a9e8921 Document why the primary plane is a special case 
For instance, i915 requires the primary plane to be enabled.

8a971695bd test: introduce liftoff_mock_require_primary_plane 
This allows to mimick i915's requirement of failing all commits
which don't have the primary plane enabled.

We could expand our test matrix to test with the param *and* without
it, but since enabling the param just makes the atomic check more
strict there's no real benefit of doing that. Enabling the param
can only make tests fail more often, not the other way around.

149e149643 Improve alloc debug logging 
Don't increase indent when skipping a plane. Better indent layer
and plane logs.

cc3eec82fd Print alloc debug logs as a tree 
The allocation process explores a tree, let's represent that tree
in the debug logs.

8f8c4d18a5 test: make sure NDEBUG is not defined 
If NDEBUG is defined, then assert() becomes a no-op. Make sure it's
not.

fe76702dfb Log number of candidate planes 
This can be useful to figure out why liftoff_output_apply returns
an empty plane allocation.

9a6a7aaa87 Make fp16_to_double static 
This prevents this internal symbol from being leaked in the
library's symbol table.

7f07d398d1 Improve prop value pretty-printing in output_log_layers 
Always print the sign when logging a signed value. Print the
full floating point value when logging an fp16 prop. SRC_X amd
SRC_Y are fp16 too.

6321e7c5aa Add needs_composition APIs 
Right now, compositors are expected to query liftoff_layer_get_plane_id to
decide whether a layer needs to be composited.

However there are cases where a layer has no plane, but still doesn't need
composition (e.g. when FB_ID is zero or when alpha is zero, in the future when
the layer is out of CRTC bounds etc).

Add a new API to make users' life simpler.

61fd4c099a Make liftoff_output_apply return an int 
Callers may want to get more details about the failure, in
particular EPERM indicates that the user isn't DRM master (can
happen on VT switch).

Also rename importance to priority and func to handler.

    passed to the "libraries" keyword argument of a previous call to generate()
    method instead of first positional argument. Adding liftoff to "Requires"
    field, but this is a deprecated behaviour that will change in a future
    version of Meson. Please report the issue if this warning cannot be avoided
    in your case.

Remove DRM_MODE_PAGE_FLIP_EVENT from commit flags 
It's illegal to request a page-flip event when performing a test-only commit.
The kernel returns EINVAL in this case [1].
