Comment(by strk):

 More over: we really want a "quick" bounding box here, using caches if
 available.
 So maybe this should not be called "Envelope" as the Geometry equivalent
 (ST_Envelope) does not use the cached bounding box at all.

 Probably what I'm looking for would be a BOX2D cast, but it seems we want
 to get rid of that type completely ? If we could get to whatever bounding
 box is quick to get and use that in bounding-box based operator it'd make
 a lot of sense to me.

 So, what's the plan here ? Adding another indexable type to replace BOX2D
 ? Gbox ?
