I posit that this code didn't compile before.

[jvanverth1, 2016/05/06 18:27:55]

Probably not.

     void inval() override;
 
     void paintIfNeeded();
 
     bool scaleContentToFit() const override { return true; }
     bool supportsContentRect() const override { return true; }
     SkRect getContentRect() override { return mContentRect; }
     void setContentRect(int l, int t, int r, int b) { mContentRect.set(l,t,r,b); }
 
 private:
     android_app* mApp = nullptr;
     SkRect mContentRect;
     int mSampleCount = 0;
+    bool mSRGB;

This should be fSRGB (despite what the other members say).
