Mateusz Łoskot f613cc4088 Remove re-assignment of functor from for_each_pixel (Trac 7092) ...

The assignment was superfluous in general case and incorrect in specific
case when the algorithm was given a lambda expression.
The copy assignment operator is defined as deleted for lambda
expressions.

Add minimal test for for_each_pixel algorithm to verify it compiles with
lambda expression.
