-///\brief Represents any entity which has a fixed size specified in its entity-definition and does not display a model (e.g. info_player_start).
-///
-/// This entity displays an axis-aligned bounding box of the size and colour specified in its entity-definition.
-/// The "origin" key directly controls the entity's local-to-parent transform.
-/// An arrow is drawn to visualise the "angle" key.
