Removes
vtkOpenGLRenderWindow.HaveVRDisplayevent. This event is unused internally and was previously left over from WebVR to WebXR integration to avoid API breakage.Under previous behavior the
navigator.xrcheck was called eagerly at construction, which could result in an unhandled exception. This change removes that eager check so thatnavigator.xris referenced only if an XR-related method such asstartXRis called.Applications should query
navigator.xrdirectly to determine whether a given session type may be supported.Resolves #2537
Also removes outdated WebVR-related TypeScript definitions from
vtkOpenGLRenderWindow. Affected method implementations were previously removed in transition from WebVR to WebXR.Context
navigator.xris only available where WebXR is supported, and sometimes appears available but is disabled for security. Queries should be limited to instances where XR is explicitly being used, or at least exceptions should be handled otherwise.Results
