[postgis-devel] ST_AddBox ST_DropBox

Do we still use these?  I thought these automatically happen?  
I'm tempted to just drop them from the docs, but not sure if there is a
reason to keep them.

ST_AddBBOX(geometry)

    Add bounding box to the geometry. This would make bounding box based
queries faster, but will increase the size of the geometry.

ST_DropBBOX(geometry)

    Drop the bounding box cache from the geometry. This reduces geometry
size, but makes bounding-box based queries slower.

Thanks,
Regina
