Well, when you cast it to bool (such as doing "if(pix)") you'll get true
if it points to anything, false otherwise.  I guess if create_from_file
fails it probably returns a clear pointer, so it'd evaluate to false.

But I don't see how that's any easier than just using try/catch --
wouldn't using normal exception handling be generally clearer?
