The xrCreateGeometryInstanceFB function is defined as:
// Provided by XR_FB_passthrough XrResult xrCreateGeometryInstanceFB( XrSession session, const XrGeometryInstanceCreateInfoFB* createInfo, XrGeometryInstanceFB* outGeometryInstance);
Creates an XrGeometryInstanceFB handle. Geometry instance functionality requires https://www.khronos.org/registry/OpenXR/specs/1.0/html/xrspec.html#XR_FB_triangle_mesh extension to be enabled. An XrGeometryInstanceFB connects a layer, a mesh, and a transformation, with the semantics that a specific mesh will be instantiated in a specific layer with a specific transformation. A mesh can be instantiated multiple times, in the same or in different layers.
