*TEST this will affect inworld sittargets by +-0.1m, so may be very BAD *. Changed the sign of the sitoffset dependent on avatar size in SP.cs. Removed that offset correction from SET/GET..primitiveParams in LSL api. If the sign needs to be the previus one, then all references to avatar positions on LSL api need to be fixed with that correction, not only SET/GETprimitiveParams.
