<pre>
Normalized bounding polygon for text (that might not be aligned with axis).
Contains list of the corner points in clockwise order starting from
top-left corner. For example, for a rectangular bounding box:
When the text is horizontal it might look like:
        0----1
        |    |
        3----2

When it's clockwise 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). Note that values can be less
than 0, or greater than 1 due to trignometric calculations for location of
the box.
