Todo List
- Class spice::
blend_function:: overlay<T> - this assumes premultiplied alpha. Generalise this to support unpremultiplied data as well.
- Member spice::
blur:: fast_gaussian (image<T> const&source, float sigma, size_t passes=5) - split treatment of channels and horizontal/vertical part into individual threads
- Class spice::
interpolation:: bicubic<T> - implement this
- Member spice::
nd_vector_impl<Dimensions, T, Owner>:: operator= (T const&value) - remove completely?
