 // The structs we're creating all copy their constructor arguments.  Given the way the SkRecords
 // framework works, sometimes they happen to technically be copied twice, which is fine and elided
 // into a single copy unless the class has a non-trivial copy constructor.  For classes with
 // non-trivial copy constructors, we skip the first copy (and its destruction) by wrapping the value
 // with delay_copy(), forcing the argument to be passed by const&.
 //
 // This is used below for SkBitmap, SkPaint, SkPath, and SkRegion, which all have non-trivial copy
 // constructors and destructors.  You'll know you've got a good candidate T if you see ~T() show up
 // unexpectedly on a profile of record time.  Otherwise don't bother.
