* This is a bit hacky right now for performance reasons.

* We assume that most footprints will have features aligned to the axes in
* the zero-rotation state. Therefore, if the footprint is rotated, we
* temporarily rotate back to zero, get the bounding box (excluding reference
* and value text) and then rotate the resulting poly back to the correct
* orientation.
*
* This is more accurate than using the AABB when most footprints are rotated
* off of the axes, but less accurate than computing some kind of bounding hull.
* We should consider doing that instead at some point in the future if we can
* use a performant algorithm and cache the result to avoid extra computing.
