…rendering logic.

    return nullptr;
  }
-  std::vector<std::shared_ptr<ImageFilter>> imageFilters;
+  if (_filters.empty() || FloatNearlyZero(contentScale)) {


这里的contentScales是否等于0是不是应该在更前面的调用源头的地方判断？

+  Recorder shadowRecorder;
+  auto shadowCanvas = shadowRecorder.beginRecording();
+  for (const auto& param : params) {
+    auto filter = createShadowFilter(param, scale);
+    if (!filter) {
+      continue;
+    }
+    Paint paint;
+    paint.setImageFilter(filter);
+    shadowCanvas->drawImage(opaqueImage, bounds.x(), bounds.y(), &paint);
+  }
+  auto shadowPicture = shadowRecorder.finishRecordingAsPicture();


同理投影的Image也不需要Recorder，用makeWithFilter直接创建。
