Overrides the automatic, volume based, computation of the prim's center of gravity. All rotations will instead be made around the given point. This includes llSetRot, llSetLocalRot, llTargetOmega as well as physics evaluation. In addition, the handles in edit mode will be positioned at the specified point.
||position of the prim's center of gravity
||boolean, if TRUE cog is relative to the local coordinate system, if FALSE cog is relative to the parent coordinate system. If the prim is a single prim or the root prim in a linked set, that means the region coordinate system.
