This commit contains:

- A fix for filename_list() function in filename_list.cxx . On GNU/Linux sort should be casted to proper type.
- Fix for image_transform.cxx demo application which makes it ready fro successfull build - after Bill's change, as he suggested, I had to cast object of Widget type in order to get value.
