I think that if you make this a plain interface, CircularRegion can implement
it. That way you don't need WebCircularRegion.cpp at all.

+public:
+    WebCircularRegion() { }
+    WebCircularRegion(const WebCircularRegion& other) { assign(other); }
+    WebCircularRegion& operator=(const WebCircularRegion& other)
+    {
+        assign(other);
+        return *this;
+    }
+
+    BLINK_EXPORT double latitude() const;
+    BLINK_EXPORT double longitude() const;
+    BLINK_EXPORT double radius() const;
+
+#if BLINK_IMPLEMENTATION
+    WebCircularRegion(WebCore::CircularRegion*);

This constructor should be marked as explicit.

+    operator WebCore::CircularRegion*() const;
+#endif
+};
+
+} // namespace blink
+
+#endif // WebCircularRegion_h
