The ini was just to showcase what you've got and point out that the initial
object orientation might not yield the tightest bounding box possible.
As a tool, I'd probably do some sort of iteration with loops, first fixing one
axis, then another, then another, and then checking to see if there's any
improvement on a second go-'round. If there is, repeat, if not, all done.

Great job Thomas - those results are surprising, given the absolute mathematical
nature of those shapes.
I would have imagined that with something like a parametric, you'd be able to
cycle through u and v real quick, and get a min and max value for each axis to
use for the AABB dimensions. I'm also still completely mystified as to why the
parametric is such a slow-to-render object, and why the triangle approximation
isn't a source-coded native primitive.
