OpenXR CTS 1.1.54.0 (2025-12-18)

-   Conformance Tests
    -   Change: Update C++ standard version used from C++14 to C++17.
        (internal MR 4096)
    -   Fix: Use correct buffer size constant for
        xrStructureTypeToString2KHR test. (internal MR 4093)
    -   Fix: Alpha channel values are to be propagated unchanged, not
        affected by conversion between linear and non-linear sRGB
        representation (internal MR 4109)
    -   Fix: Remove leading newline from generated include file for
        shader. (internal MR 4127)
    -   Improvement: XR_EXT_spatial_marker_tracking: If QR code has
        string data, check that the string ends with a null terminator.
        (internal MR 3913)
    -   Improvement: XR_EXT_spatial_marker_tracking: Replace “REQUIRE”
        with “CHECK” for marker component data because we can still
        continue to render the markers and test the bounded2D component
        even if the marker component data is invalid. (internal MR 3913)
    -   Improvement: XR_EXT_spatial_marker_tracking: Create “update
        snapshot” for discovered markers so that we render them at their
        latest pose. (internal MR 3913)
    -   Improvement: Add checks for
        XrEventDataSessionStateChanged::time. (internal MR 4048)
    -   Improvement: Add additional test instructions for
        XR_EXT_hand_tracking interactive test. (internal MR 4073)
    -   Improvement: Add additional test instructions for
        XR_EXT_spatial_anchor interactive test. (internal MR 4074)
    -   Improvement: Force all tests to be printed in test XML.
        (internal MR 4103)
    -   Improvement: Fix -Wmissing-prototypes compiler warnings.
        (internal MR 4107)
    -   Improvement: Fix -Wdeprecated-literal-operator warnings in CTS.
        (internal MR 4108)
    -   New test: Verify the presence of VK_KHR_image_format_list in the
        Vulkan device extension list when
        XR_KHR_vulkan_swapchain_format_list is enabled if
        XR_KHR_vulkan_enable2 is also enabled in
        XrApiLayer_runtime_conformance. (internal MR 3781)
