OpenXR SDK 1.1.37 (2024-05-23)

This release primarily adds new defines for easier use of both OpenXR
1.0 and 1.1 with up-to-date headers, some documentation improvements,
and improvements for Android, including support for using the “API Dump”
and “Validation” API layers in your own APK during the development
process.

-   Registry
    -   Addition: New XR_API_VERSION_1_0 and XR_API_VERSION_1_1 defines
        to allow applications to easily specify OpenXR “major” and
        “minor” version while passing through the “patch” version.

    -   Addition: Register Razer vendor ID. (internal MR 3340)
    -   Fix: Add “palm_pose” to “touch_controller_pro” and
        “touch_controller_plus” in XML. (internal MR 3363)
    -   Improvement: Add Schematron rule to avoid triggering edge cases
        of vendor tags ending with X. (internal MR 3341)
    -   Reservation: Reserve extension numbers for a few new EXT
        extensions. (internal MR 3285, internal MR 3292)
