Sets position and orientation of entity

physinterface.h

bool bEntGridUseOBB;

whether or not to use part OBBs rather than object AABB when registering in the entity grid

int bRecalcBounds;

tells to recompute the bounding boxes

int iSimClass;

see the sim_class enum

Matrix33 * pMtx3x3;

optional orientation via 3x3 matrix

Matrix34 * pMtx3x4;

optional position+orientation

Vec3 pos;

quaternionf q;

float scale;

note that since there's no per-entity scale, it gets 'baked' into individual parts' scales
