Align with `subsampled_view` overloads accepting `point_t` and `coord_t` Both types are based on `std::ptrdiff_t`. Fixes compilation warnings. Tidy up `subimage_view` and `subsampled_view` with trailing return. Add tests for `subimage_view` in core and dynamic_image extension. (First tests for the dynamic_image, hurray! :)) Add explicit cast to double in division operator for point<T> to fix compilation warnings.
