BoundingBox

public BoundingPoly BoundingBox { get; set; }

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:
```
  2----3
  |    |
  1----0
```
and the vertex order will still be (0, 1, 2, 3).
