Changes for Windows Mixed Reality VR:

• Added support for temporal post-processing of motion vectors (same algorithm as Windows Mixed Reality for SteamVR). Improves the quality of motion reprojection.
• Added support for Nvidia Optical Flow as a source of motion vectors. Improves the quality of motion reprojection on Nvidia RTX cards only.
• Added option "Prefer frame rate over latency". This option allows an application to render frames faster at the cost of additional latency. It can be used in conjunction with motion reprojection. This is similar to the so-called "Turbo Mode" in the 3rd party application "OpenXR Toolkit".
• Moved motion reprojection rendering to a high-priority command queue to prevent interference from the application.
• Fixed a hang in Digital Combat Simulator when motion reprojection is enabled.
• Fixed a bug with transparency when using motion reprojection.
• Removed "Automatic" motion reprojection mode (which only meant "Enabled only in Flight Simulator 2020").

General changes:

• Fixed miscellaneous issues and OpenXR conformance issues.
