///\brief Represents any light entity (e.g. light).
///
/// This entity dislays a special 'light' model.
/// The "origin" key directly controls the position of the light model in local space.
/// The "_color" key controls the colour of the light model.
/// The "light" key is visualised with a sphere representing the approximate coverage of the light (except Doom3).
/// Doom3 special behaviour:
/// The entity behaves as a group.
/// The "origin" key is the translation to be applied to all brushes (not patches) grouped under this entity.
/// The "light_center" and "light_radius" keys are visualised with a point and a box when the light is selected.
/// The "rotation" key directly controls the orientation of the light bounding box in local space.
/// The "light_origin" key controls the position of the light independently of the "origin" key if it is specified.
/// The "light_rotation" key duplicates the behaviour of the "rotation" key if it is specified. This appears to be an unfinished feature in Doom3.
