X3D output optional options arg for flipping coordinates and output bbox

[robe]

This will be similar to the opt argument we have for ST_AsGML. Except for flipping we might need 3 as in many applications I think its the y and Z that are flipped and y is negated or something. I'll have to double-check on that with my X3D expert partners.

The option I'd like to have is output as a constrained bounding box (the geometry envelope) -- which bit 32 for GML.

More useful to me would be an arbitrarily oriented minimum bounding box (as described here --  http://en.wikipedia.org/wiki/Minimum_bounding_box) , but I don't think I'll be getting that in in 2.0 as the algorithm is much more complicated.

okay guess this will have to wait.
