[3.0.0] - 2019-11-05

Renaming the concept of Reference Points to Anchors. The Unity script updater should convert any references to XRReferencePointSubsystem, XRReferencePoint, and XRReferencePointSubsystemDescriptor the next time the project is loaded into the Editor.

Change TrySetFocusMode to a property called focusMode, enabling providers to implement a getter as well as a setter.
Added classification on BoundedPlane which provides contextual information such as Floor, Wall, Ceiling.

XRCameraImagePlane.ToString() invoked NativeArray.ToString() to build its string, which produced a string with a lot of irrelevant information. Now, it just displays the length of the array, row stride, and pixel stride of the plane.

Added an input device layout for the Input System, for use by individual providers.

Updated the interface for all subsystems to apply a consistent pattern across all subsystems. This affects subsystem implementations (such as ARCore and ARKit) but should not affect consumers of those subsystems.
Removed supported property on the XRFaceSubsystem. Providers (such as ARKit) are expected not to register themselves if they are not supported.
Removed supported property on the XREnvironmentProbeSubsystem. Providers (such as ARKit) are expected not to register themselves if they are not supported.

Updated package version to 3.0.0-preview.2 for consistency with other AR-related packages.

Add support for reference image libraries that are modifiable at runtime. For platforms that support it, this allows you to add new reference images at runtime.

Add support for eye tracking.
Added an XRParticipantSubsystem which can track users in a multi-user collaborative session.
Add support for exposure duration
Add support for exposure offset
Add support for Lightweight Render Pipeline and Universal Render Pipeline.
Add support for height scale estimatation for the 3D human body subsystem.

Add support for NotTrackingReason.
Add support for getting the ambient light intensity in lumens.
Add functionality to the XRSessionSubsystem to enable synchronizing the Unity frame with the AR session update. See XRSessionSubsystem.matchFrameRate and XRSessionSubsystem.frameRate.

Fix CameraFocusMode handling in XRCameraSubsystem. This fixes an issue when running on a provider that does not set the default focus mode to CameraFocusMode.Fixed.

Adding support for ARKit 3 functionality: Human pose estimation, human segmentation images, session collaboration, multiple face tracking, and tracking a face (with front camera) while in world tracking (with rear camera).
