OpenXR SDK (Source) 1.0.29

OpenXR SDK 1.0.29 (2023-08-25)

This release contains several fixes to the specification registry, improvements
to the loader, layers, and loader test, as well as enhancements to the loader
documentation/specification to support architecture and ABI specific active
runtime manifest names on Linux and Android.

• Registry
  • Change PFNEGLGETPROCADDRESSPROC (for eglGetProcAddress) to a locally
    defined type to avoid compiler errors.
    (internal MR 2468)
  • Extension reservation: Register author ID and reserve vendor extensions for
    YVR.
    (internal MR 2832)
  • New vendor extension: XR_META_passthrough_preferences
    (internal MR 2694)
  • XR_HTCX_vive_tracker_interaction: Added new role paths for wrists and ankles.
    (internal MR 2728)
• SDK
  • Changes also included in 1.0.28.1 SDK hotfix release
    • layers: Build with /bigobj or equivalent on Windows due to increased number
      of generated functions with spec growth.
      (internal MR 2837,
      internal issue 2051,
      OpenXR-SDK-Source PR 414)
  • Changes also included in 1.0.28.2 SDK hotfix release
    • Android AAR artifacts (loader) and hello_xr: Fix <queries> element contents.
      (internal MR 2840,
      internal issue 2053)
    • Android AAR artifacts: Fix C++ standard library selection for Android artifacts
      in build-aar.sh
      (internal MR 2836,
      internal issue 2052)
    • Android AAR artifacts: Use jar instead of 7-zip to perform archiving, and
      document requirements in build-aar.sh
      (internal MR 2836,
      OpenXR-SDK-Source issue 303,
      internal issue 1711)
    • build system: Support SDK hotfix versions (fourth version component).
      (internal MR 2836)

    (internal MR 2876)
  • Add build.gradle files for list_json, c_compile_test.
    (internal MR 2908)
  • Change PFNEGLGETPROCADDRESSPROC (for eglGetProcAddress) to a locally

    (internal MR 2468)

    (internal MR 2790)
  • Fix building hello_xr with mingw compiler.

    (internal MR 2810,
    internal MR 2842)
  • Maintenance script updates.
    (internal MR 2900)

    Linux, macOS, and Android.

    internal issue 2066,
    internal MR 2871)
  • loader: refactor to use jnipp on Android
    (internal MR 2812)

    (internal MR 2843)

    (internal MR 2865)
