// Face attribute bits, used in first part of string preceding each shape
// array (before file name) in shape file e.g. "0020 B0002_01.pgm" means
// that the face in image B0002_01.pgm is wearing glasses.
//
// The same defines are used to specify attributes of individual landmarks
// in landmarks.hpp:gLandTabAll e.g. FA_Glasses means that this landmark is
// obscured if the subject is wearing glasses
//
// FA_BadImage marking is subjective and not entirely consistent.  I just
// wanted to weed out images that seemed likely to confuse the classifier
// during training.  Certainly all _really_ bad images are marked
// FA_BadImage; marking is inconsistent only on marginally bad images.
//
// FA_NnFailed means that the Rowley neural net detector did not find one
// face and two eyes in the image.  Typically this means that the face is
// of poor quality or is wearing glasses. ("Nn" stands for "neural net").
