OpenXR SDK 1.1.40 (2024-08-22)

This release features a new ratified graphics API binding extension, XR_KHR_metal_enable, including support in hello_xr. The loader test has had substantial improvements as well. There are also an assortment of smaller fixes and improvements. - Registry - Add: New ratified Khronos extension: XR_KHR_metal_enable. (internal MR 2721) - Chore: Reserve 15 extension id numbers for ByteDance. (internal MR 3409) - Fix: Clarified that views in XR_VARJO_quad_views needs to have identical poses for each eye. (internal MR 3396) - Fix: Add missing interaction profile extensions for OpenXR 1.1 promoted Meta interaction profiles. (internal MR 3398) - Fix: Correctly mark the Magic Leap home button as a system button in the XML. (internal MR 3405) - Fix: Add XR_ERROR_VALIDATION_FAILURE to all functions from XR_EXT_conformance_automation. (internal MR 3417) - SDK - API dump layer: Improvement: Move a non-generated function out of the Python- generated source file. (internal MR 3336) - API dump layer: Improvement: Clean up usage of RAII mutex lock guards. (internal MR 3336) - Layers and loader: Improvement: Disambiguate XrGeneratedDispatchTable between loader and API layers. (internal MR 3406) - Loader test: Improvement: Migrate to use Catch2 (matching the CTS) instead of an ad-hoc test framework. (internal MR 3337) - hello_xr: Add: Metal graphics plugin (use -g Metal) for running it on macOS with XR_KHR_metal_enable extension. (internal MR 3009, internal MR 3456) - hello_xr: Improvement: Use XrMatrix4x4f_CreateFromRigidTransform in place of XrMatrix4x4f_CreateTranslationRotationScale for known rigid transforms. (internal MR 3349) Note: There is no 1.1.39 release: it was skipped to keep the monthly patch version increment cadence given the lack of a release in July.
