Detailed Description
template<typename T>
class DualCoding::Sketch< T >
Smart pointers for referencing.
SketchData<T>
instances
This is the structure that provides safe user-level access to sketches. It's a smart pointer that does reference counting, and overloads operator-> so it can do validity checking. If the validity check succeeds, operator-> dereferences to a SketchData<T> object.

This is a shallow copy: it does not copy the underlying pixels.
Shallow copy constructor used by NEW_SKETCH and NEW_SKETCH_N.
