/// The STAGE reference space is a runtime-defined flat, rectangular space that is empty and can be walked around on. The origin is on the floor at the center of the rectangle, with +Y up, and the X and Z axes aligned with the rectangle edges. The runtime may not be able to locate spaces relative to the STAGE reference space if the user has not yet defined one within the runtime-specific UI. Applications can use <see cref="xrGetReferenceSpaceBoundsRect">xrGetReferenceSpaceBoundsRect</see> to determine the extents of the STAGE reference space’s XZ bounds rectangle, if defined.
///
/// STAGE space is useful when an application needs to render standing-scale content (no bounds) or room-scale content (with bounds) that is relative to the physical floor.
///
/// When the user redefines the origin or bounds of the current STAGE space, or the runtime otherwise switches to a new STAGE definition, the runtime must queue the <see cref="XrEventDataReferenceSpaceChangePending">XrEventDataReferenceSpaceChangePending</see> event, with the new STAGE space origin only taking effect for <see cref="xrLocateSpace">xrLocateSpace</see> or <see cref="xrLocateViews">xrLocateViews</see> calls whose <see cref="XrTime">XrTime</see> parameter is greater than or equal to the changeTime provided in that event.
///
/// When views, controllers or other spaces experience tracking loss relative to the STAGE space, runtimes should continue to provide inferred or last-known position and orientation values. These inferred poses can, for example, be based on neck model updates, inertial dead reckoning, or a last-known position, so long as it is still reasonable for the application to use that pose. While a runtime is providing position data, it must continue to set XR_SPACE_LOCATION_POSITION_VALID_BIT and XR_VIEW_STATE_POSITION_VALID_BIT but it can clear XR_SPACE_LOCATION_POSITION_TRACKED_BIT and XR_VIEW_STATE_POSITION_TRACKED_BIT to indicate that the position is inferred or last-known in this way.

/// Across both virtual reality and augmented reality, XR applications have a core need to map the location of virtual objects to the corresponding real-world locations where they will be rendered. Spaces allow applications to explicitly create and specify the frames of reference in which they choose to track the real world, and then determine how those frames of reference move relative to one another over time.
///
/// Spaces are represented by XrSpace handles, which the application creates and then uses in API calls. Whenever an application calls a function that returns coordinates, it provides an XrSpace to specify the frame of reference in which those coordinates will be expressed. Similarly, when providing coordinates to a function, the application specifies which XrSpace the runtime should use to interpret those coordinates.
///
/// OpenXR defines a set of well-known reference spaces that applications use to bootstrap their spatial reasoning. These reference spaces are: VIEW, LOCAL and STAGE. Each reference space has a well-defined meaning, which establishes where its origin is positioned and how its axes are oriented.
///
/// Runtimes whose tracking systems improve their understanding of the world over time may track spaces independently. For example, even though a LOCAL space and a STAGE space each map their origin to a static position in the world, a runtime with an inside-out tracking system may introduce slight adjustments to the origin of each space on a continuous basis to keep each origin in place.
///
/// Beyond well-known reference spaces, runtimes expose other independently-tracked spaces, such as a pose action space that tracks the pose of a motion controller over time.
///
/// When one or both spaces are tracking a dynamic object, passing in an updated time to <see cref="xrLocateSpace">xrLocateSpace</see> each frame will result in an updated relative pose. For example, the location of the left hand’s pose action space in the STAGE reference space will change each frame as the user’s hand moves relative to the stage’s predefined origin on the floor. In other XR APIs, it is common to report the "pose" of an object relative to some presumed underlying global space. This API is careful to not explicitly define such an underlying global space, because it does not apply to all systems. Some systems will support no STAGE space, while others may support a STAGE space that switches between various physical stages with dynamic availability. To satisfy this wide variability, "poses" are always described as the relationship between two spaces.
///
/// Some devices improve their understanding of the world as the device is used. The location returned by <see cref="xrLocateSpace">xrLocateSpace</see> in later frames may change over time, even for spaces that track static objects, as either the target space or base space adjusts its origin.

/// <summary>
/// The XrPath is an atom that connects an application with a single path, within the context of a single instance. There is a bijective mapping between well-formed path strings and atoms in use. This atom is used — in place of the path name string it corresponds to — to retrieve state and perform other operations.
///
/// As an XrPath is only shorthand for a well-formed path string, they have no explicit life cycle.
///
/// Lifetime is implicitly managed by the XrInstance.An XrPath must not be used unless it is received at execution time from the runtime in the context of a particular XrInstance. Therefore, with the exception of <see cref="OpenXRHelper.XR_NULL_PATH">XR_NULL_PATH</see>, XrPath values must not be specified as constant values in applications: the corresponding path string should be used instead.During the lifetime of a given XrInstance, the XrPath associated with that instance with any given well-formed path must not vary, and similarly the well-formed path string that corresponds to a given XrPath in that instance must not vary.An XrPath that is received from one XrInstance may not be used with another. Such an invalid use may be detected and result in an error being returned, or it may result in undefined behavior.
///
/// Well-written applications should typically use a small, bounded set of paths in practice.However, the runtime should support looking up the XrPath for a large number of path strings for maximum compatibility. Runtime implementers should keep in mind that applications supporting diverse systems may look up path strings in a quantity exceeding the number of non-empty entities predicted or provided by any one runtime’s own path tree model, and this is not inherently an error. However, system resources are finite and thus runtimes may signal exhaustion of resources dedicated to these associations under certain conditions.
///
/// When discussing the behavior of runtimes at these limits, a new XrPath refers to an XrPath value that, as of some point in time, has neither been received by the application nor tracked internally by the runtime.In this case, since an application has not yet received the value of such an XrPath, the runtime has not yet made any assertions about its association with any path string. In this context, new only refers to the fact that the mapping has not necessarily been made constant for a given value/path string pair for the remaining life of the associated instance by being revealed to the application.It does not necessarily imply creation of the entity, if any, referred to by such a path.Similarly, it does not imply the absence of such an entity prior to that point. Entities in the path tree have varied lifetime that is independent from the duration of the mapping from path string to XrPath.
///
/// For flexibility, the runtime may internally track or otherwise make constant, in instance or larger scope, any mapping of a path string to an XrPath value even before an application would otherwise receive that value, thus making it no longer new by the above definition.
///
/// When the runtime’s resources to track the path string-XrPath mapping are exhausted, and the application makes an API call that would have otherwise retrieved a new XrPath as defined above, the runtime must return XR_ERROR_PATH_COUNT_EXCEEDED.This includes both explicit calls to xrStringToPath as well as other calls that retrieve an XrPath in any other way.
