 Current implementation for for_each_pixel is somehow re-assigning the
 functor to its own variable. [[BR]]

 This becomes a serious problem '''when using a C++11 lambda-expression'''
 for the functor. [[BR]]

 Since the copy assignment operator for lambda-expressions is declared
 ''deleted'' by the standards, this makes it unable to pass lambda-
 expression for the functor of for_each_pixel. Obviously this is a serious
 problem for writing C++11 style codes.[[BR]]

 See attached patch for suggested workaround.
