///\brief Represents any Doom3 entity which does not have a fixed size specified in its entity-definition (e.g. func_static).
///
/// This entity behaves as a group only when the "model" key is empty or is the same as the "name" key. Otherwise it behaves as a model.
/// When behaving as a group, the "origin" key is the translation to be applied to all brushes (not patches) grouped under this entity.
/// When behaving as a model, the "origin", "angle" and "rotation" keys directly control the entity's local-to-parent transform.
/// When either the "curve_Nurbs" or "curve_CatmullRomSpline" keys define a curve, the curve is rendered and can be edited.
