From: chris yeoh <yeohc@au1.ibm.com> 

Attached is a patch for LLGround which was just plain broken and could
cause a runtime error. It now returns valid data with valid input (ie
the offset does not take the position off the edge of the sim), but a
runtime error will occur if invalid data is given.

On invalid data the LL servers return the ground height based on a
valid point closest to the effective position calculated using the
supplied offset. Is the OpenSim convention to replicate the LL servers
as closely as possible? If so I can submit an additional patch to
replicate the LL behaviour.
