// Extract a set of standard-sized features from Blobs and write them out in
// two formats: baseline normalized and character normalized.
//
// We presume the Blobs are already scaled so that x-height=128 units
//
// Standard Features:
// We take all outline segments longer than 7 units and chop them into
// standard-sized segments of approximately 13 = (64 / 5) units.
// When writing these features out, we output their center and angle as
// measured counterclockwise from the vector <-1, 0>
//
// Baseline Normalized Output:
// We center the grapheme by aligning the x-coordinate of its centroid with
// x=0 and subtracting 128 from the y-coordinate.
//
// Character Normalized Output:
// We align the grapheme's centroid at the origin and scale it asymmetrically
// in x and y so that the result is vaguely square.
//
// Deprecated! Prefer tesseract::Classify::ExtractFeatures instead.
