Description
Add an opt option similar to what ST_AsGML has to allow outputting coordinates in a different orientation and also just the bounding box of the geometry.
Ideally would have an option to output a true mimimum bounding box (arbitrarily orientated minimum bounding box) not just an axis aligned one. As described here:
http://en.wikipedia.org/wiki/Minimum_bounding_box
Once I figure out how compute that.

This would be quite useful, as X3D has a y-up coordinate-system, while postgis is z-up. So currently all exported objects are rotated by 90°. I would even go as far as calling this a bug, since it violates the X3D specifications.

Hmm looks like I did put in an axis ordering (though looks to just flip x,y) rather than the Z which is the common case you mention.

I'll try to accomplish this for 2.5

renaming the subject since axis ordering was implemented in 2.2
