Orientation Example:
====================
Above is a diagram of some (1) English and (2) Chinese text and a (3) photo credit.

Upright Latin characters are represented as A and a. '<' represents a latin character rotated anti-clockwise 90 degrees. Upright Chinese characters are represented C and c.

NOTA BENE: enum values here should match goodoc.proto

If you orient your head so that "up" aligns with Orientation, then the characters will appear "right side up" and readable.

In the example above, both the English and Chinese paragraphs are oriented so their "up" is the top of the page (page up). The photo credit is read with one's head turned leftward ("up" is to page left).

The values of this enum match the convention of Tesseract's osdetect.h
