The bounding box for the block.
The vertices are in the order of top-left, top-right, bottom-right,
bottom-left. When a rotation of the bounding box is detected the rotation
is represented as around the top-left corner as defined when the text is
read in the 'natural' orientation.
For example:
when the text is horizontal it might look like:
0----1
| |
3----2
when it's rotated 180 degrees around the top-left corner it becomes:
