enables an ordered chain of full-screen post processing effects

In some case, Discrete Fourier Transform in computeSaliencyImpl() returns
magnitude matrix which contains zero values.
Then, log() returns -inf values and normalization with blur() returns -nan.
When computeBinaryMap() is called double free or corruption exception occurs
because kmeans() fails to compute distance.

Added if condition, whether faces are detected or not, will help to keep program running for some images.

* remove bug when src is vector Point2i in FourierDescriptors

* remove unused code and comments

`near` is an illegal variable name on Windows (if `windef.h` is included),
because a macro with the same name is defined.

Someone else already put your rage into words, see
