* Prepare errorscopes logic in wgpu_thread * remove scope_id from ipc * new GPUErrors per spec * remove cotent timeline error_scope * fixup poperrorscope types * device_scope -> gpu_error and nice errors * Handle errors detection more elegantly * good expectations * new expectations * Make error_scope.errors Vec as per spec
