@brief Set the "collide" bitfield for the given geom.
The collide bitfield is used by spaces to govern which geoms will
interact with each other. The bitfield is guaranteed to be at least
32 bits wide. The default category values for newly created geoms
have all bits set.
@param geom the geom to set
@param bits the new bitfield value
