OpenXR SDK (Source) 1.0.17

OpenXR SDK 1.0.17 (2021-06-08)

This release features an important fix to the loader for an invalid-iterator bug
introduced in 1.0.16. All developers shipping the loader are strongly encouraged
to upgrade. It also includes a variety of new vendor extensions.

• Registry
  • Add XR_MSFT_scene_understanding vendor extension.
    (internal MR 2032)
  • Add XR_MSFT_scene_understanding_serialization vendor extension.
    (internal MR 2032)
  • Add XR_MSFT_composition_layer_reprojection vendor extension.
    (internal MR 2033)
  • Add XR_OCULUS_audio_device_guid vendor extension.
    (internal MR 2053)
  • Add version 3 of XR_FB_swapchain_update_state vendor extension, which splits
    platform and graphics API specific structs into separate extensions.
    (internal MR 2059)
  • Apply formatting to registry XML by selectively committing changes made by
    https://github.com/rpavlik/PrettyRegistryXml.
    (internal MR 2070,
    OpenXR-SDK-Source/#256)
  • Enforce that all xrCreate functions must be able to return
    XR_ERROR_LIMIT_REACHED and XR_ERROR_OUT_OF_MEMORY, and adjust lists of
    error codes accordingly.
    (internal MR 2064)
  • Fix a usage of > without escaping as an XML entity.
    (internal MR 2064)
  • Fix all cases of a success code (most often XR_SESSION_LOSS_PENDING)
    appearing in the errorcodes attribute of a command.
    (internal MR 2064,
    internal issue 1566)
  • Improve comments for several enum values.
    (internal MR 1982)
  • Perform some script clean-up and refactoring, including selective type
    annotation and moving the Conventions abstract base class to spec_tools.
    (internal MR 2064)
  • Sort return codes, with some general, popular codes made to be early. Script
    sort_codes.py can be used to maintain this, though it mangles other XML
    formatting, so use it with care. https://github.com/rpavlik/PrettyRegistryXml
    can format, and eventually sort return codes (currently sort order does not
    match).
    (internal MR 2064,
    OpenXR-SDK-Source/#256)
• SDK
  • Loader: Fix iteration over explicit layer manifests.
    (OpenXR-SDK-Source/#256)
  • validation layer: Don't try to apply strlen to wchar_t-based output
    buffers.
