it seems like a SkPictureContentInfo and SkPictureContentInfoImpl would help ---
the the onDrawPoitns, etc is stuff thats part of the implementation of the
interface.

class  SkPictureContentInfo {
public:
numOps()
hasText()
suitableFor()

private:
  int fNumBlah.
}

class  SkPictureContentInfoImpl : public SkPictureContentInfo {
 addOperation
  onDraw*
  onAddPaintPtr
}

class SkPictureContent {
   const SkPictureContentInfo& contnt_info();
private:
  SkPictureContentInfoimpl_ info_;
}

+public:
+    SkPictureContentInfo() { this->reset(); }
+    SkPictureContentInfo(const SkPictureContentInfo& src) { this->set(src); }
+
+        bool numOperations() const { return fNumOperations; }
+        bool hasText() const { return fNumTexts > 0; }
+        bool suitableForGpuRasterization(GrContext* context, const char **reason,
+                                     int sampleCount) const;
+
+        void addOperation() { ++fNumOperations; }

+        void onDrawPath(const SkPath& path, const SkPaint& paint);
+        void onAddPaintPtr(const SkPaint* paint);
+        void onDrawText() { ++fNumTexts; }
+
+    void set(const SkPictureContentInfo& src);
+    void reset();
+    void swap(SkPictureContentInfo* other);
