DOMFloat32Array can be forward declared here.

Unfortunately not, as it's a typedef

+#include "modules/sensor/Sensor.h"
+
+namespace blink {
+
+class OrientationSensor : public Sensor {
+  DEFINE_WRAPPERTYPEINFO();
+
+ public:
+  Vector<double> quaternion(bool& isNull);
+  void populateMatrix(DOMFloat32Array*, ExceptionState&);
+
+  bool isReadingDirty() const;
+
+  DECLARE_VIRTUAL_TRACE();
+
+ protected:
+  OrientationSensor(ExecutionContext*,
+                    const SensorOptions&,
+                    ExceptionState&,
+                    device::mojom::blink::SensorType);
+
+ private:
+  // SensorProxy override.
