Isn't this comment wrong now?

Done.

     void setTexture(GrTexture* texture, const GrIRect16& rect) {
-        if (NULL != fTexture) {
-            fTexture->unref();
-        }
-
-        fTexture = texture; // just take over caller's ref
+        SkRefCnt_SafeAssign(fTexture, texture);
         fRect = rect;
     }
     GrTexture* texture() { return fTexture; }
