Tabular output support for Text/OCR

[28mm]

Of the supported API providers, only Microsoft and Google have OCR functionality. Google reports the text it finds, along with associated bounding boxes. Microsoft probably does something similar. Perhaps two tabular output modes make sense:

1. a mode that prints recovered text in top->bottom and left->right order
2. another modes that prints the associated nesting bounding boxes.

Have yet to give this a close look.
