This driver does nothing but set the HMD's resolution option. It defaults to the highest "safe" value without AMDGPU DSC patches.

- Running_OK → tracked 6DoF:
ORIENTATION_TRACKED | POSITION_TRACKED |
ANGULAR_VELOCITY_VALID | LINEAR_VELOCITY_VALID.

- Fallback_RotationOnly and Running_OutOfRange → tracked 3DoF:
ORIENTATION_TRACKED | ANGULAR_VELOCITY_VALID.
(No POSITION_TRACKED; no LINEAR_VELOCITY_VALID.)

- Calibrating_* results are not marked TRACKED.

When poseIsValid, keep ORIENTATION_VALID and POSITION_VALID, but gate
TRACKED and velocity-valid flags on the SteamVR result to avoid treating
inferred poses as actively tracked and to reduce drift/jumps.

Eigen changed from 3.x versioning to semver (3.5 became 5.0) and
dropped FindEigen3.cmake module support (deprecated in prior versions)
for config discovery.

Switch from find_package version constraints to manual version checking
to maintain compatibility with both versioning schemes (>= 3.3 old or
>= 5.0 new).

Vive Pro 2 for some reason has this flipped, so we need to do our own flip to rectify that.

Replaces the individual constructors with one constructor that mimics
the API used by opencv, and takes a distortion_model parameter to
allow use with fisheye distortion models as well.

Depending on the start-up config, when comp_window_peek
is enabled, in some cases the required Vulkan instance
extensions for SDL2 are not being enabled, causing
functions such as SDL_Vulkan_CreateSurface to fail.
